Bumpy ride after Thuren upgrades

[Kr0ss]

Tire psi? The rears should be significantly less than the front to get it to work right……unless you’re towing or loaded heavy then tire psi needs to come up.

Thanks - I'm currently running 34-36lbs all around (the reading changes daily). Should I go up in the rear or down in the front?

Did the 37’s go on simultaneously with the suspension, or were they on there before?

The 37s were on with stock springs & shocks before this upgrade.

Are you running air bags or timbrens. Honestly Don is the man to answer instead of the internet peeps. He’s a bit backed up but usually will respond within the week. Or reach out to Andrew at Thuren as well.

No, suspension is stock minus front and rear Thuren shocks/springs + front trackbar.

its been hashed out before. your driving over roads with expansion joints every 8' or so. 800lb axles going up and down several times a second sends those forces through the springs to the frame and the shocks arent able to control it

The rear tires should have considerably less air than the front…unless towing or loaded down.

put sidewalk chalk on the treads. front end is about 1000k heavier but i wouldnt go considerable higher pressure. chalk will tell you what to do

I'm running Thuren rears springs, proper length Bilstein 5100 series, 50 psi in 35's, airbags with daystar cradles (2-10 psi used as bump stops depending on load). Mine is floaty, not bouncy. Front's done the same (with no airbags of course). Best bang for the buck upgrade I've done to any truck. I can blitz speed bumps at Home Depot with a cup of coffee in my hand and the truck gobbles up washboard dirt roads here in the SoCal desert which is what I needed. Shocks will get hot and fade but good for several miles of "Baja 1000 practice" which is a treat as opposed to stock which felt like the dash was going to rattle out of the truck.

I'm having all 4 tires rebalanced just to confirm that's not the issue.
Thanks for the advice, I'll try the chalk method after the rebalance is complete.

Is it more of a floaty feeling or is it more of sharp small bounces....

Bounces, so rapid that it almost feels like a vibration. It's not constant, but its frequent at certain speeds, so I'm trying a tire balance just to rule that out.
