Suspension still stiff and jumpy after overhaul

[CTUBS8732]

Recently overhauled my suspension and steering. Used a TRQ kit from 1A Auto and also just put new bilsteins 5100s front and rear. Replaced sway bar bushings as well. Only bushings not replaced are the lower control arm bushings and lower control arm shock absorber mount bushings.

Truck still rides rough and when I hit bumps in the road it feels like my truck is taking a beating.

Well, 5100s do deliver a stiffer ride than stock. I would suggest finishing the replacement of the other bushings. However, I cannot imagine that the quality is that of OE for that price for all of those parts. While mine is a different generation, rebuilding my front end with all OE parts last year cost over $3K in parts, I reckon it's much higher this year. It rides like an old Cadillac and handles the turns like a Monte Carlo!

Everything I replaced was shot and worn. I wanted to go with everything oem but in my current situation I don’t have the funds to purchase ac delco which I wish I could. Got the shocks at a steal from a buddy who recently sold his Tahoe. (Brand new)
But as for a Cadillac ride I did not get lol. I got a super stiff ride and when hitting bumps it still feels like I have bad shocks. I don’t have the boat effect going on it’s more like my wheels and jumping when hitting bumps.

Have you checked Z-angle on your control arms? Did you level the truck? What load rating tires are you running?

I rebuilt my 2001 with energy suspension bushings, and 5100's. It has leveling keys but I cranked them down so 1" higher in back. I have Load Range E tires (10 ply). My truck is VERY comfortable but no Cadillac to ride in.

Do your RPO codes include G65 and ZW7? If so, that's Premium Smooth Ride. If those PSR rear shocks are changed to conventional shocks, the springs should be changed, too.

Yup g65 and zw7 @Fless

Also, how do you do a z check? Never heard of it.
And I didn’t level the truck.

I'm wondering what the rear shocks look like -- the ones you replaced. Were they substantially larger in diameter than a typical shock? They may have been the Nivomat self-adjusting shocks.

The shocks on the front were about the same size. New ones were a bit longer.

New Rear shock were noticeably smaller in diameter.
Old ones were real fat.
