Just wondering why no IFS lift companys push the front tires forward an inch or so to allow bigger tires to be run, by no hitting the back of the fender under compression.

Seems to me with the CV shafts they could handle an inch or 2 offset of the tires.

Seems it would be easy by making a offset spindle. If you pushed the tire forward a bit you could fit much larger tires with a smaller lift. And its much easier to trim the plastic front bumper rather than the fender

Im sure im gonna get shit for this question but i was just thinking about it

yes makes sense but the guys who build our trucks put ifs on them...ifs is not the strongest setup out there...therefore, they might not have wanted us to run bigger tires cause we could break shit...so, they didnt think it was necessary to try to make it so we could run bigger tires.

just my thoughts on it.

I was always under the impression that the 2500 IFS was beefy enough to handle up to a 40 with out to much problems. At least i thought i read that in the solid axle/IFS debate thread that i started

I ran 37's very hard for 93k and every had to replace anything other than a wheel bearing

Even the OEM brakes had 40% left when i sold it with 93k on it

It just seems that since the lift companys are always trying to get the upper hand on the market, that it would appeal to alot of us here on DP, cause everyone wants bigger tires. I mean come on. thats like asking if we want to roll more smoke, or have more power

o believe me...im right there with ya. i ran an 8'' lift and 37s on my last dmax and it didnt really like it.

no offense at all but from the look of your truck it doesnt seem like it goes off road often so you should be able to live with big tires on ifs for a good while. i beat the hell out of my trucks and i have had some problems running huge tires on the ifs. upgraded they live just fine but stock doesnt cut it. im running cognito steering upgrades and 33s on my 03 and havent had any problems...stainless tie rod sleeves going on this next week.

the fact is that ifs was not made for big time off road or huge tires...it was made to ride nice. with the right mods it can be just as reliable as a solid axle and ride much better.

Yea i do not take my truck offroad much, at the most it would go in the snow or a logging road. But im not wheeling the 50K duramax. they suck offroad anyways. there like a big anchor.

IFS was not meant to wheel by any means. excpet for like a toyota IFS with the downey kit. I had that on my 89 sr5 and i could jump it like 5 feet in the dunes it was great.

I just want 40's!! stupid fenders

haha yeah. great looking truck you have there. i do miss the solid axle for wheeling purposes as i hunt and wheel my truck pretty hard but with some pretty reasonable mods it takes the abuse fine and rides so much nicer doing it.

Ya, i would love to have a long travel IFS kit on my Dmax that moved the front tire 1.5 inches forward and increased the front travel to about 14"

that would be sick, even if it was a street queen.......... I bet it would not be that hard to do, im getting ideas............ideas cost money. better stop thinking.

Holy crap, i just realized i have spent about 8 hours on thedieselplace today, thats pathedic

actually i have a buddy that does fab work for a living and i have been tossing around ideas with him about doing a long travel kit for my truck that will keep the 4wd. still in the planning stages but being the guinea pig truck i will get the homie discount. hopefully i can pull the funds together by the time he wants to build...an 8000lb truck doing 120 through the desert blowing smoke is about as badass as it gets. all it takes is money...haha.

The hardest part to making it work is getting the CV axles to slide in and out, You have to build new front axles that are splined so they can go in and out a few inches, where CV's dont move that much, Making the control arms would be the easy part. and the steering can be achived with hiems and highmisalignment spacers

The Superlift bracket system moves the entire front end forward. Just some FYI.

I don't get this guys, how was an IFS not designed to go off road? I have taken my truck on trails and such. Never had a problem, if your talking about extreme wheeling ok yeah IFS has limitations but for most off road use IFS is fine.

40's might be OK for a pavement princess, but it just won't work offroad without a big lift, and then it jeopardizes stability. Got a few around town here with bigger tires, and honestly, I just don't get it. They never see a dirt road, much less real offroading, and a few are even 1/2 tons just waiting for the axle to snap. As for the 2500's and 40's, you can stuff whatever you want in the fenders with some modifications, but you'll find the weak link soon enough. I wouldn't do it w/o a SFA, personally.

You would also need a longer driveshaft.

I mean it can handle some things yes. No im not trying to advocate wheeling a 2500hd hardcore. I just think it would be cool to have a Long travel beefed up IFS, up front. Cause no one has them.

And yes for just light trails and tooling around IFS is just fine. However if you start jumping it or pouding it hard you will Unspring your torsion bars and have to recrank them tighter just to get back to normal ride hieght. (ask me how i know, I did it on my SR5 in the dunes) Or bend your subframe and never get it aligned properly

The major issue i have with IFS is the inability to keep both rear tires on the ground at all times due to the front not flexing at all, and the rear does all the work, when flexing. Drives me nuts

How are you correlating the inability of flexing an IFS with the inability to keep the rear on the ground? Are you referring to keeping all 4 on the ground from articulating?

I think it's worth mentioning that it's not that IFS in general sucks off road, it's just OUR IFS sucks.....:D They do use it on trophy trucks, and baja vehicles.

I think the problem you guys are going to find with your long travel kit is that all of our travel is in droop relative to the center line of the CV's, we have probably 4-5" of travel wasted in compression because the bump stops keep the suspension from ever going much past level.

That leaves you with two option, first is drop the center section and leave the A-arms where they are at, this will let you use more of the travel of the current CV's. Problem with that is you can't go far without hanging the diff below the cross member. The other option is to lengthen the CV's by either stretching out the track width or narrowing the center section, if you lengthen the half shafts by 1" you can gain about 3/4" of travel assuming a 30 degree max angle on the CV's. If you can get 45 degrees out of the CV's then it's almost a 1" to 1" ratio.

I've got a little suspension fab experience if you want any help. Granted it was on a Mini Baja racer, it still had 10" of travel out of honda four wheeler CV's.

Yes, I was talking about articulation and pulling a rear tire prematurly due to the front having limited flex and the rear drooping out faster than if you had equal droop front and rear. If that makes sense

and yes ifs can be bad ass. Like a baja bugs or throphy truck

but ours lacks a little to be desired

Bumper clearance for sure would be an issue. Also 2" would add at least 15 degrees of angle to the cv which would not be good. The solution would be to move the a arm mounts and the diff forward along with a longer driveshaft and probably a moved sway bar as well. That is a lot of work and a lot of cost which i bet couldnt be packaged easily in to a kit.

I think what you'll find is that you're not going to get much better than what's available on the market right now......without resorting to a full "cut and past" of the entire front end forward of the firewall. Once you're to this point it WILL be custom and expensive.
