I have a SRW Denali 2500HD that had squat and bounce issues. Changing the shocks to Ranch 9000s helped. Installing the Sumo Solo 1500 totally fixed the problem. Running on the edge of weight on this truck. Ordered a 2020 3500HD AT4. First thing I did was order Sumo Solo for it.

They are currently just under $150 on Amazon.
The Chevy/GMC install is simple, pop or the standard bump stop insert with a screw driver and twist/press in the Sumo’s.
I believe this is the same part for the DRW, but you can check their site to be sure.
