question regarding RC lift

I added a RC lift 3" to my 2000 XJ. The rear is over an inch higher than the front. I was told by RC that the the new leafs would settle in 10-14 days. Its been 6 weeks. Anyone have had this issue?

thanks

Re: question regarding RC lift

Did you torque the leaf spring bolts with the tires on flat ground ? What have you done to promote leaf spring break-in ? Ideally you would disconnect the sway bar if present, load up with several hundred pounds of cargo, and then flex the springs repeatedly over some obstacles.

Re: question regarding RC lift

RC isn't the best Cherokee lift kit available, but since you own it, give it a try.

New leaf springs can be stiff and can result in taller than expected lift. The break-in period can accelerated. A day on the 4x4 trails would be the ideal break in.

thanks Tim, does the rear sway bar have any effect on the hight of the leafs? I am also running stock rear shackles.

Re: question regarding RC lift

The sway bars will reduce flex on the 4x4 trails, lengthening the break-in period. Most people remove the rear sway bar when installing lift kit leaf springs. The shackles should be fine as is.

I should add that with a lifted Cherokee, the bump stops must be longer than stock, because over compressing leaf springs and/or bottoming out shocks is not good for them and can cause permanent damage.

Tim, I live on the Gulf Coast in Mississippi. I will be doing tail riding/overnight camping with some light hills. We have generally flat ground. The norm around here is to go muddin. I will not be muddin. What can i do to a 2000 4.0L 3" RC lift kit 31"s, 231TC to improve performance? I plan on upgrading the steering with the ZJ V8 set up. Rear end is just a stock Dana 33. Looking for small upgrades that i would benefit from.

Thanks Buddy

I see you from the twin cities, I work for a large company based in the Twin Cities.

Re: question regarding RC lift

The steering is fine as-is, the Dana 35 not so much. The Dana 35 is the least desirable XJ axle because it has the potential to snap axle shafts even with an open differential and small tires.

If you have all the necessary on trail repair tools, self-recovery gear, skid plates and tow hooks, commonly needed spare parts, extra fluids, survival gear and food, your best upgrade would be a much more durable 29 spline Chrysler 8.25 rear axle from a 97-01 XJ Cherokee. Swaybar disconnects are beneficial. If the budget allows, a LockRight type locker in the Chrysler 8.25 rear axle will add to the off-road capabilities of your XJ.
