I doubt it is the shocks causing the problem , Bilstein build some of the best shocks & usually give a great ride , so it is more likely the spring rates are to high .
So the other question is what size tires & wheels are you using & what pressure are you running in the tires ?

If you're running 32 psi in those tires that is definitely too much pressure! I only run 20 psi in the 275/60-15s on the rear of my Cuda and 28 psi in the 235/70-15s on the front and I get a great wear pattern.

Back in the day it was running mid 13's @ about 102 MPH with an old Chrysler 392 Hemi. I swapped in a Gen III 5.7 Hemi later on and I have not had a chance to put it on the track to see what that engine will do. The 392 had so much torque off the line it would blow off any kind of street tires So I got the MT's to solve that issue. The first time I launched with those tires was an eye opener, instant hook!😁

If your Bilstien shocks are stock height for an ebody, there's a good chance they are bottoming out due to the lower height of the Hotchkis leafs. This is exactly what was happening with mine, the stock shocks (and the stock ebody height QA1's I replaced them with) only had about 2 inches of travel left at the lower ride hight and it didn't take much of a dip or bump to compress them totally which will deliver the ride you're feeling. I measured the distance between the center of the upper and lower shock bolts and called QA1 for a better fitment. Based on my measurements, they recommended part number TS709 which is a single adjustable shock spec'd for 67-72 Chevy C10 pickups. It's a shorter shock and now my rear suspension has full travel without coming close to fully compressing the shock, which gave me a much better ride. Doesn't have to be QA1 but that's the direction I went to solve the issue I was having.

A not uncommon problem with many E body owners especially when the car is lowered, @73Dodge is all over this issue. You need to do some research and measuring before throwing parts at it.

If memory serves, the Hotchkis hangers have two positions. The lower hole corresponds to the stock hanger position and the upper will give you an additional 1 inch drop on top of the -1 inch drop the leaves themselves are advertised for. The previous owner of my 73 left the stock hangers in as well and I was still sitting lower. The QA1 shocks are excellent, if I could do it again I would buy once, cry once and get double adjustables on all four corners. Being able to dial in the compression and rebound separately is a great benefit that you can feel on a day at the strip or cruising around.

73 dodge nailed it shocks are too low in the travel the shocks don;t rebound as fast as they compress and going over all those expansion joints on that concrete road made it squat a little thanks for everyones help
