I installed a tuff country 4inch lift with toyo MT 287/75/R16 load range E set at 60psi front and back. I also have a ranch hand bumper on the front and back. I was wondering what could cause my ride to be so rough? I had to get a new cross member and torsion bars and keys for my truck and i hope the torsion bars are in the stock setting since i didn't get to mark them. My axle's are flat and everything looks good, but when you hit a bump you almost blast through the roof. any ideas? Also how do you know if the torsion bars are right?

maybe drop your PSI's a tad?

post a pic of ow much travel you have on the UCA bump stop.

Crank them bars up a little and should help with your ride. Also will level out the cvs instead of being angles upwards

Thanks i will try that today

i had the same issue and switched to bilstien 5100's and it was a night and day difference. you can run lower psi also. i ride around unloaded with 55psi on mine
