[Art64]

Give it some time for the suspension to settle down or "break-in." I don't know exactly what term to use here for the suspension. But after a few months of use, the suspension will soften. I have an 06 V6 reg cab and that thing bounces off like there's no suspension at all. Super hard, the suspension won't give or compress when I'm driving over speed bumps and dips. My stock battery's acid is spilling from the vents because of too much bouncing. Hard to keep the truck to run straight on the freeway. Always wandering. SO I put 150 Lbs of gravel in the back next to the cab. I drove it like that for a few months and now the suspension is normal. It compresses when I go over speed bumps and dips. Much more stable on the freeway even at high speed or windy conditions. Now , Don't need the extra weight on the back and removed it. Go off roading on some uneven terrain. Work out that suspension. You don't have to go fast off road. Just make sure the suspension gets a work out. Put some weight on the bed. Do this often. If it doesn't soften the suspension, then go back to Chevy.
