Truck rides like a brick.

the truck bounces like crazy.
I loosened my torsion keys all the way and that helped?

So you're riding directly on the bump stops, fully crushing them. And completely collapsing the shocks into their "control zone"...

The 8-lug RPO was C6P; from there it's broken apart into two sets if you want to be super specific, 350 trucks typically got the 14-Bolt SF 8-lug, and 454/6.5L trucks got the 14-Bolt FF 8-lug.
On the ride of the truck, it's a 3/4 ton truck from the 90s, not a caddy; but you can still make them ride decently.
Start with all the bushings, 20+ years is way past the life span for the rubber bushings in anything, small things like GMT800 cab mounts can help but at the end of the day it's still a 3/4 ton Chevy.

The 1500 in my sig, ECSB, has 1 ton torsion bars and 8600gvw leaves out back, same as you OP. It rides shittier than the dually in my sig, a CCLB. I have 2 CCLB duallies and they ride the same. Better than my 1500.

Thanks for all the replies. I just figured it was HD because of the gvwr. Thanks for clarification. I could tell the torsion bars were slightly cranked so I lowered them all the way. I guess I didn't even think about the bump stops. Ill screw in the keys up today and see how it does. I am still thinking about a tuff country lift. I know their rear leafs are considerably better. I have the same leafs in my 1980 K30 and its amazingly better than stock was.

As far as tire pressure I think I'm st 50 in the front and 80 in the rear which is what the door tag says to have them at. They are retread k02s. I wish I had falken wildpeak at3s on. They are a much better tire.

If you are thinking about a lift, I just installed WFO shackle reversal kit on my k2500, ecsb and it made a big difference in ride quality and that’s with the basic RC shocks that came with my lift kit. No blocks and it nets about 4 inches lift with 5 inch shackles. I also installed a u bolt flip kit at same time/ kept overload leaf.

Air pressure plays big role. One of the tahoes I had, I put Goodyear wrangler authority’s on it, 235/85/16 on stock wheels. First had 34-35lbs I think, road like it was on a cloud. Pumped em up to 45-50, road like a tank and were louder than hell. Try air pressure n see what it does....

Good info. I think I may try that.

I'll play around with it and see what happens.

I dropped air pressure to 50 in the rear. Huge change. It rides like my heavy half did!
