Revtek and Daystar both make 2-inch lift kits that aren't too difficult to install, but the rock climbers around here typically lift 4", and many to 6" or more. A rock-climbing neighbor of mine drives both a 2001 Jeep Wrangler (4" lift) and a 2005 Jeep Liberty (3" lift); he deals mostly with a company named Rocky Road Outfitters (I use their strut install kit, it makes strut removal, servicing, and re-installation a comparatively easy, quick job). Rocky Road presently campaigns a 2008 Jeep Liberty (KK, same in most respects as the KA Dodge Nitro) and you can get specifics here (Jeep Liberty parts and accessories, KJ (also known as the Cherokee still outside of the USA)). They do not recommend a lift over 3" because of CV joint reliability issues, but they offer everything you can imagine for a permanent, reliable, safe modification.I seen a pic of a silver one that someone had put a lift on and larger tires does anyone know what all is involved with this?I think it looks cool myself and thought about lifting mine but wanted more details before I proceed
Surprisingly, unless you're interested in cutting or eliminating the fender well liners, even with a 3" lift you're limited to a overall wheel+tire diameter of no more than 30.5 inches...the same diameter you can use with no lift at all!
