I've been scouring the web for a budget friendly, yet solid 3.5 inch lift for my '97 ZJ. I always hear good stuff about IRO and their 3.5" benchmark kit is just the right price. However, I don't understand how it works that the OEM front springs get moved to the rear, and new springs are put into the front. Wouldn't that make the Jeep unlevel? More stiff in the front than the back? Blablabla...I just figured that the OEM springs would be the same length front and rear. Can anybody clarify how it is possible to get a 3.5" lift and level ride by moving front springs back?
