jokerchief462 The U bolts are a fixed assembly and deserve the torque. But once the lift is installed with the shackles snug the suspension needs to be cycled to settle in place. The stock shackles on mine did not move after the install at the recommended torque. I replaced them with some boomerang shackles and nylon lock nuts. Cycled and torqued to 45 ft/lbs. they cycle and move at a touch. Just bump the Jeep and they move for a smoother ride.

My specs say 65 for the shackles and 70-85 for the u-bolts

WGHyrum Common mistake that can make an awesome lift turn rock hard. Never torque a suspension when it's not under load.
Glad we could be of assistance.

c5wagner Sweet that worked out really well, I didn't realize the u-bolts could make it smoother. I should've put the kit on myself instead of trusting the idiots who installed it. Everything was torqued to around 60 ft lbs. Now I wish I did the soa lift instead but hey. Thanks a ton

I can look up the specs if you need them. I have them around here somewhere.

bigtoysforbigboys Try loosening your shackles while its sitting on the ground and re torque them

c5wagner Still a rough ride, and I've pulled out the track bars and sway bar already.

Take them out. It'll also save wear on your shackles and leafs. Leaf springs aren't meant to move sideways and track bars force them sideways a little bit.

Any ideas how to fix a very rough suspension

I have a 1989 wrangler with a 2.5" rancho lift, and well my car has a very rough/stiff ride. Is there anyway to smooth out the ride or is this a common problem I'm stuck with?
