Strut Data
Info to correct
Hi, i want to relive this post just to correct the info on the OP, i have an JDM 1999.09.2 iO, so it has the MR519093 front strut, according to KYB the replace for this part is the KYB 334405 (already mesured the distance discussed in this thread and obtained 267mm). here is the KYB equivalents from the KYB catalog (MR519093 OEM equivalent is KYB 334405).
The data of the OP should be corrected to this:
1998.05.1 - 1998.09.2 - MR319792 - Tokico B3311 - KYB 334442 - or in Europe KYB 334813
1998.09.3 - 1999.07.3 - MR455401 - Tokico B3311 - KYB 334442 - or in Europe KYB 334813
1999.08.1 - 1999.09.3 - MR519093 - Tokico B3312 - KYB 334405
1999.10.1 - 2000.04.3 - MR519092 - Tokico B3312 - KYB 334405
2000.05.1 - 2001.09.1 - MR554614 - Tokico B3312 - KYB 334405
2001.09.2 - 2007.06.3 - MR992092 - Tokico B3312 - KYB 334405

Are you saying that your strut ref KYB 519093 is 267 mm
Interesting....
Happy io
Exclusions
Yeah, and that explains why the other brands excludes the MR319792 & MR455401.
an example:
Notes: Front: for original APA-KYB struts only - excl. KYB OEM no. MR319792 & MR455401
well, then KYB 334405 is
well, then KYB 334405 is around 20mm more hight than KYB334442(in Europe 334813), its raise the Io around 20mm, right??
But what about shocks travel? is 20mm more travel in extension?
i need to know it, i have ironman spring around +35mm and with lower pan struts(334442) i have problems whit the travel in extension,that comes to the limit very fast, I need more travel.
KYB 334405 will fix my problem?
No

No - the only difference between the two struts is the position of the spring perch.

No - the KYB334405 will make the situation worse - assuming you want to keep the Ironman springs, the solution is a strut extender - this moves the top of the strut down by 50mm - folks have made them or had them made by a machine shop, from the tops of old struts, cut, drilled & tapped. This allows more droop, but be warned, too much droop can cause problems with the CV angles.
I am very serious.
Read the sticky thread on lifts at the top of the forum and then read this same thread a second time - look closely at the pictures.
The difference between the two struts is the position of the spring seat - the pan on which the bottom of the spring sits - when you change from the 334442 strut to the 334405 strut you're moving the bottom of the spring further away from the road, that moves the top of the spring and the entire vehicle further away from the road which is in effect lifting it.
There are two different struts and two different springs - pick a strut, match it with the correct spring and there is no change in ride height, use the 334405 strut with the spring for the 334442 strut and there will be a small lift.
The travel on the struts are the same - so as the vehicle is lifted there is less droop and that is what is causing your problem.
thanks Fordem
I have the iron man performance +40mm springs Reference MITS0034B front and MITS0035B for IO. one week ago.
Now my Io is more comfortable on road, but i dont understand why in a typical hole of water puddle on the mountain way, its looks like the shocks absorber hit on the extender limit. or maybe this is the sensation and the problem is to this springs are very hard and my 3doors io havent weight enough... i dont know.
Has anyone used these springs?
Ironman springs
Most of the guys here who have used lift springs seem to have used King springs, and seem to be happy with them - a few guys have used Dobinsons springs, only one person seemed to be happy with them - that person was running a five door, there were a couple of guys who tried them in the three door and found them too hard - perhaps similar to what you are experiencing - I believe you are the first user on here with the Ironman springs.
Over the weekend I started a "spring data" thread to gather as much data on the springs as I could - the spring rates are in there.
Try measuring the eyebrow height (from the bottom edge of the rim to the arch) with the weight on the wheels and then measure again with the wheel off the ground - this way you can determine how much down travel or droop your suspension has - if it's less than 30~40mm - your problem is the limit of the strut extension.
ok. i will do it tomorrow and
ok. i will do it tomorrow and comment here.
For example, if my io was the 5 door version ( more heavy car) i probably lose a little lift, but what about the travel with the same springs/strut?
Im thinking to buy this skid plates in steel 2mm...

Hello Lamping, have a bit of
Hello Lamping, have a bit of read here http://pajerio.com/forum/kingspring-and-kyb-mix I think that your spring doesn't match your strut, similar problem as described in that thread. Measure your droop as Fordem said, that will confirm the problem or give us more info.
Happy io
Hi again, it is 20-25 mm
Hi again, it is 20-25 mm travel ... im so sad of course this is the problem.
- What happend if i install the steel skid plates and i get more heavy car? it can fix my problem?
-And what if i mount this ironman springs on 334405? more hard suspension and less strut travel?worst?
i think this hit on max extension strut is dangerous for me/my car offroad
Unfortunately - this is "unexplored" territory.
Because no one else has used the Ironman springs, you have to find the answers yourself - we can only make suggestions - adding weight to the front will help, but I really don't think that skidplate will make a big difference, as for the 334405 struts - definitely a step in the wrong direction.
My suggestion - if you can return the ironman springs is to go with the King springs - all of the guys on here who have used them are happy with them - if you can't return them, consider a strut extender like I showed you.
This is like if we are
This is like if we are starting to flog a dead horse when it comes to suspension on front and rear so I will start with the front.
Now taking into account I had the low pan front strut and not he high and fitting 225/75/16 tyres were a pain in the arse because the hit the bottom of the pan.
When I 1st bought my 99mod io is was all stock so I started looking for options to raise it and in my reseach with what was on this forum and personal searching I haveI found that king springs do give lift. But i wanted more travel when in the bush and that's when my reseach started (6.5hrs) at the wreckers). I found that the Nissan X-trail 2005mod was the same as the iO compressed but extended gave an extra 50mm (2inch) more travel and because the lower spring pan was 35mm higher than the iO it gave an instant lift but saying that there are a couple of things needed to be done to make them fit properly and I have had them in for over 12mths and still no problelms except for when I added a 25mm spacer on top of the strut and the drivers side inner cv popped so without the spacer they are fine and at their limit unless you do a diff drop to compinsate then you are fine.
Getting to the rear I put the ford laser/mazda front spring on the rear and again instant lift, I think I got them out of a 1996 ford laser and then added the standard hilux shocks on the rear but you need to take the brake line out of the last bracket before it goes to the rubber hose and it gained me 65mm more travel in the rear which also comes in handy when in the bush and you barely lift wheels as it walks thru the rutts and at that stage I didn't think about the pan hard rod and ended up snapping mine in half because of the extra travel in the diff.So I tried the commodore adjustable one and ended up bending it so made my own heavy duty adjustable and it's perfect.
Warning if you put the king springs on the rear with the Hilux shocks they sound like they are falling out because they don't extend long enough like the laser/mazda springs do even tho the Kings do give lift.
I have 2 iO's, a 99 and a 01mod and would not put the king springs in if you combine them with the hilux shocks in the rear and also have noticed that the king springs in the front make more noise than what the laser/mazda springs do as they don't make any noise when extended fully..
I really hope this helps some of you guys out and help set-up your car the way you want it.
Happy Motoring.
Already i cant return my iron
Already i cant return my iron man, and i like how they raise my car 
Keith65 , Nissan X-trail 2005mod what is the product code? can you send a link? and you said ""there are a couple of things needed to be done to make them fit properly"" i need to know all of it.
Fordem, i have found a used homemade part (35$).photos.
40mm, what do you think how it can work in 334442 (low)? with this piece my travel will be 20mm + 40mm??
And what if i use the strut 334405(high) + this piece + the ironman springs? works good too? ( in a future i want to buy 225/70/16 BFG a/t KO2)
Thanks for all guys, iam learning a lot about the car and english!!
Let,s not confuse the issue unnecessarily.
Foredem not all the guys, I wouldn't use the king springs as they don't extend far enough especialy on the rear.
Keith - I don't believe there is anywhere in the forum where you mention having tried the King springs, and I don't believe I have seen you publicly state that you're unhappy with the King springs - within the last week or so I have extensively reviewed many of the threads on lifts and do not recall seeing anyone complain about the King springs once the correct spring has been paired with the correct strut - I've seen complaints about King springs when used with the wrong strut, and Dobinsons when used on SWB vehicles - I believe you have presented the Xtrail struts as an alternative way of acheiving longer travel on the front.
Feel free to assist Lamping with the details of the Xtrails struts and let him make his decision - I've looked at the modifications required to keep the vehicle usable and personally, I'm not prepared to go that route - and whilst I'm about it, let me ask you this - I believe you're in Australia - if your car, with those modifications went in for an inspection - what's the probability of it being "defected" and your being told to return it to stock?
When I'm through lifting my car, it will pass local inspection.
Lamping
Based on those pictures, and measurements that I took when making strut extenders those extenders may not be long enough to screw "completely" on to the struts you have - you'll have to try them - when screwed on they should fit all the way down so that they look like a part of the strut.
Yes - they will give you an additional 40mm of droop or down travel with the 334442 struts - if used with the 334405 struts you will have about of 35mm of droop which I think is marginal.
wow Fordem! You are the best
wow Fordem! You are the best !!
The "seller" told me about i must cut a little milimeters in the thread strut. i think this is not a big problem, what do you think??
I have thought long time...
- I think that if I want to keep the springs(ironman), the best will be 334442 + this extender + 215/70/16 BFG A/T ( biggest possible as i read here)
-The other possible solucion: 334405+old original spring+225/70/16 BFG A/T
Please master, guide me!
One of the first "rules" for me...
is that modifications should, as far as possible, be reversible - cutting a perfectly good strut can only be reversed by buying a new one.
Having said that - I am not sure that shortening the threaded portion of the strut is safe - it will depend on how much it needs to be shortened and also I believe that the D shaped portion of the strut is longer - you will have to try it and see for yourself.
My iO is currently fitted with 334442 struts, the rod from the original Mitsubishi struts were cut to make strut extenders - just in case they are needed - and those are at the machine shop right now - I discussed it with the machinist (who thinks the idea is crazy - but he will make them for me because I have explained that other people have done it) and we agreed that 50mm is perhaps the shortest "safe" length, but that is based on not cutting the working strut.
I am in pretty much the same position as you are - about to purchase lift springs - Dobinsons in my case - and then explore my options - I'm planning to use the 334405 struts, hopefully I won't need the extenders, but if I do, they will be on hand.
Which direction you take will really depend on your situation - I want to use a larger tire (I'm already running 215/70R16) so the 334405 struts are a necessity, I would prefer a stiffer spring that the original spring - the Dobinsons are both shorter and stiffer, and are supposedly designed for what I'm doing - and if all else fails, I will still have the option of putting everything back to stock.
I am not sure of having
I am not sure of having understood everything... you remember I'm from Spain and I was not the best student...
During this time, any problem with 334442 + 215/70? there is any rubbing problem?
About the extender, you could get one perfect for my? where are you? I would pay the amount of the work and the shipment without doubt it.
Stiff?? I cant imagine one more stiff than the ironman!! the wear for the use and the time it will more soft?
agreed
Agreed with Fordem, just adding some info, concern.
The spring will not get softer or very very little.
The 215/70/16 should be fine with the 334442...I think that is what Fordem have now ? (used to have 215/65/16 ?)
You clearly understood the fact that we have 2 strut, one low spring pan, one high spring pan. You also understood that getting the high spring pan strut with the spring from the low spring pan will give you a lift. The problem we had with the kingspring was that they were making only one lift spring (for the low spring pan) and that we only could get the high spring pan as a new strut, both didn't match together and gave no droop. With your spring it is similar problem, no or not enough droop BUT you do have the low spring pan strut. This does make me think that your spring are even longer, probably too long, and may give you too much lift at the front. Sorry if it is a bit confusing !!
Fitting the strut extender will work and will give you the extra droop you need but you may then have too much travel for your CV. I mean that the wheel travel can be modified but if your wheel gets to low at full extension it will create problem with your CV and ball joint, I think it will be the case here.
It is hard for us to tell you at 100% to say do this or that, as it is a unkown area ! it is a little bit like a puzzle, just have to find the correct fitting.
Are you strut extender machined to be fitted ? How much lift gave your new spring ?
If your strut extender can be fitted, and if you can do the work yourself, try them on without cutting your strut, or driving with the car....just a try fit. This will able you to test if that set up will work. Let us know if you can do that before going further.
Happy io
Claude you have a phenomenal memory!
Yes - I am currently running 215/70R16, which is the OEM size for my car, and yes, I was running 215/65R16 at one time - before I got my front suspension sorted.
Back to the strut extenders - a 50mm strut extender will allow an additional 50mm of droop, and the general consensus seems to be that an additional 50mm of droop won't be too much for the CVs, anything more than that and you need to start looking at diff drops or some form of limiting - the guys running the Xtrail struts would/should be able to provide more detail on this.
Lamping - I'm down in South America - shipping strut extenders from here would cost a small fortune - let me check with my machinist to find out if he can make these from scratch, what he's doing for me is tapping & drilling a pair of cut down strut piston rods - I'll also check to see if the Suzuki strut extenders will fit these struts, those can be sourced out of the UK, which should make them a lot more feasible for you.
xtrail strut
KEITH65 I hope that you may have a little free time to continue the conversation. I am really interested in all the options. also which will help to others in the future.
What Keith have done is already mentioned several time, above included, and very well know already, just type "Xtrail strut" in the search and you will find his modification.
Happy io
Thanks for all your comments
Thanks for all your comments Claude, and sorry for my late answer but your english is hard for me 
At this moment i dont have the strut extender on my hands. this is just a possible solution what i found in Spain from a man whit the same problem as i have, and right now he is on inserts koni and sell this homemade piece.
iron man thinkness, i promise post it as fast possible in the other thread.
Now the xtrail struts, i see this thread and i need know few things about it, and i need the Keith65 experience.
we can continue it here? or in the other thread?
Lamping, I have given
Lamping, I have given detailed info on the X-trail struts several times as Claude iO has mentioned and apart from the inner drivers side CV popping out it only did that because I added and extra 25mm spacer on the top of the strut and like I said as soon as it happened i removed the spacer.
The differance between the iO's low pan, high pan and the X-trail is the X-trail pan is higher than both iO struts and i have the low pan iO spring on the X-trail strut which give a automatic lift of around 40-45mm and an extra 50mm more droop which is so much better when in the bush 4wdriving and so far I have no problems with cv's breaking or any other problems but another bonus with the X-trail strut is that you can put a much larger tyre on but then you will probaly have them rubbing on the inside at full lock.
But to make them fit there are a couple of things that need to be done which is noted in previous comments on other pages and how to do it.
As Claude said type in X-trail struts and you will find what you are looking for.
Over here in Australia we use
Over here in Australia we use the Toyota Hilux shock on the rear, they are around 65mm longer and give more flex in the rear diff but not sure what part number they are now. Also there is a extended Hilux shock which is around 110mm longer than the iO shocks which I am yet to try.
Claude io knows the part number for the hilux shocks.
nice. I hope Claude can tell
Nice. I hope Claude can tell the reference.
But +65mm can be too long and be a problem with my +35mm ironman springs?
Someone know the OME-018?
rear shock
Nice. I hope Claude can tell the reference.
But +65mm can be too long and be a problem with my +35mm ironman springs?
Someone know the OME-018?
The longer shock don't match with the ironman spring, that spring is too short and will fall on full extension of the shock. The Mazda astina spring is longer and work well with the longer shock, not the kingspring or the ironman.
Happy io
Claude is right about the
Claude is right about the springs, I have 2 iO's. 99mod with the mazda/laser springs and hiliux shocks and have no problem but the 2001mod with king springs and standard iO shocks you can hear the spring falling out of the top cup so if you go with the longer hilux shocks you will need the longer mazda/ford laser front springs to put in the rear and they give lift also and I personally think with the combo of rear X-trail struts on the front and the mazda/laser springs on the rear the car handles better on the road and way better off-road because of the extra flex front and rear.
It feels like a totally different car when set-up in this way. But i am keen to try the extra long Hilux shocks one day to see how the car performs off road.
Sorry I can't give part numbers for the rear X-trail struts all I know is I got them off a 2005mod.

I looked up front dampers on
I looked up front dampers on a parts-dealer site I trust and it came up with the part number so I just googled it on bing, but I guess it could be wrong, it definetaly sounds wrong.
I went out and meassured, mine was 28 CM, kinda ruined my day but I got a new project for the summer at least :)
I'm #1 so why try harder.
