Outer Limits 4x4 Board

does it matter if i use an ifs spring for the back off my lux off say a new model lux or an older one? are there any differences in length or anything else or are they all the same as long as its off an ifs truck? any ones better than others?
cheers sam

There all average, if thats your truck in your avator you wont get them to flex any better if as good as that.

better off spending a few more dollars and getting some custom mains made to IFS length so they work well.

hey mate.
thats my old truck.
what would be the difference between getting some made up to ifs length and using a standard ifs spring modified using my old sparing pack leafs?
my new truck has standard rears and the shackles stand nearly straight up and down.
this is the rear end flex at the moment with standard spring. flex is pretty good but i thought adding ifs rears and giving the shackle some more angle it might give it that bit extra without having to spend big on full custom packs?

anyway back to my original question is there any difference between ifs rears over the years if soo which ones are best?
cheers sam

Standard rears: 530mm front half, 670mm rear half

IFS rears: 560mm front half, 740mm rear half

Coil Front: 610mm front half, 690mm rear half


I've heard the earlier IFS rears have more arch.

But in the end, you only really need to use the top one or two to get the length, and just make a pack up to suit your height and stiffness.

Soo really the only difference between Ifs rears is how long I want my wheel base. Looking at it from that info my best bet would be early model ifs rears? Made into a custom pack from my old rears?
Would that be the best idea without spending massive amounts on custom made packs?
Any input is appreciated.
