Real bad tire hop?
 

my car STILL tire hops real bad after a set of relocation brackets. any ideas? ive tried the LCA's in both positions.

adj. panhard bar?

Bad shocks or springs or pinion angle

I agree. Could be shocks, LCA bushings could be shot, pinion angle or better torque arm. I think one of those will fix the issue. You didn't waste money on your relo brackets though. They def help in putting power down.

PHB shouldn't make much of a difference. That is keeping the lateral movement stable. You want to keep the suspension travel and forward/backward movement stable.

My car only does with street tires on it i am guessing cause the diameter and rubber difference

i have new pan hard bar, lca's and torque arm w/ bushing for relocation crossmember. im gunna fuck around with the pinion angle but its tough with out a drive on lift. i have New shocks but they are just GM replacement DeCarbons. just funny that the car never hopped with all the same suspension shit except the 9 inch. i think its geometry and not the parts them selves. But thanx for all the ideas. now i have to spend more money! Fucking Fuck!

Were you ever able to actually use a gauge to check the pinion angle on a lift? I watched a video once on how to check and set pinion angle with the gauge, it was definitely a precision operation, seems like if it was off even a little it could cause problems.

pinion angle. maaaaaybe shocks, but more likely P/A

Your shit is adjustable why more money? stfu lol

If I need better shocks! Well see. I'm pretty sure don got the angle right. But ill go threw the whole setup again. It also hopped with the 9inch and the stock torque arm as well.
