Sumo comes in different durometer ratings(hardness). I think they are designated for easy identification by color. If you have installed the wrong one it will RUIN your ride. If hard enough, the suspension won't compress.
We once installed the wrong offroad shocks (Rough Country brand shocks on the Bravada wasn't the best choice) and barely made it home. Absolutely ruined the vehicle.
When having 31's installed on an 800lb chenwoth sand rail, the shop put 40psi in a tire that would use 8psi for that particular vehicle... We didn't make it a mile down the road before it damn near killed us. It was hopping down the road and the slightest bump made it go airborne.
So... We've experienced the wrong choices you might have made. You haven't supplied enough information for anyone to help you with your question.
Which sumo kit, what sway bar, bilstein rating, tire psi front and back, are the minimum info needed.
