Hey MO...question	Permalink

Was looking on the web site at this: http://motionoffroad.com/catalog/index.php?main_page=product_info&cPath=12_52&products_id=87 However, I have read that putting much over 2" of lift on an IFS stresses the axles because of the alignment they are placed into after the lift. I am not very knowledgeable on Rock Krawler itself, or the lift and I know you put a lot of time into looking into products. Can you shed any light on any of this for me by chance. __________________ 2008 4Dr. JK Sahara Air Assault!! Http://www.militaryjeepers.com

The main problem lifting a vehicle with IFS is the increase in the angles of the CV joints. Too much and they will bind up. They might last for awhile, but they will fail sooner or later. Most likely sooner.

I have ZERO knowledge on how much a Liberty can be lifted before this might happen. Rock Crawler might have figured all this in when they came out with their 3.5" lift though. So MO will have more info on this than I.

Thats a sweet kit, I'm gonna have to show it to a buddy,

anyway-full size chevy trucks and s10's I guess have a "budget" lift that gos up to 3-3.5" with out any problems (kinda the same deal as your KJ). 4" and up is when u have to do a full on suspension upgrade with all the "bs" involved. Don't know too much about the KJ's but yours would look good with some 31's under it biggrin

Yeah I agree, it would look a ton better with some 31s setting comfortably underneath it. I don't want them to look stuffed under there and I would think the 3.5 would give plenty of space as 3 on an XJ is more than enough for 31s. Like I have stated I really want to make this trail worthy and I know I will at least need 31s to come close.

We sell a ton of the Rock Krawler lifts and components. Rock Krawler has a lifetime abuse-proof warranty on all it's "hard" parts. You break/bend/destroy a hard part it'll be replaced with no questions asked.

We do sell a lot of this specific kit for the KJ's and we've never had a complaint about them. The forks are super beefy. Rock Krawler used to sell a larger lift for the KJ (7") but when Jeremy and Heather bought Rock Krawler a few years back they disconnected that lift and also totally redesigned the 3.5" lift to eliminate any of the problems that they had in the past.

As Kim stated, when lifting a IFS Jeep you have to deal with the CV shaft angles. The new forks with the RK help this a lot. If you were to just throw a lift coil in there like a lot of the other KJ kits on the market you do not solve the issue of the angles. The RK kit does this by having replacement forks in their kit.

You'll have no issues with 31" tires on this lift. We've got customers running 32x11.5" Maxxis Bighorns even.

Let us know if we can be of any further help.
