You have a couple of options. First off what shocks are you running? Duals? I don't recommend dual shocks on anything that doesn't get a lot of abuse or pre-running. I've always been a big fan of Bilstein 5100 series shocks and just put a set of 5125's on my K-20 removing the dual Rancho setup it came with which were all bad, and that significantly helped the ride. Just make sure and spec out the correct lengths. The 5100's are slightly softer than the 5125's I believe.

Secondly, if you have a 6 inch all leaf spring lift, you could try and pull a couple leafs out of the spring packs which will lower you down some and soften it up a bit. This will be at a cost of load capacity so consider that when doing it. This can be fixed with an air bag overload setup or some Timbren bump stops fairly easily.

Poly bushings on your shackles will transfer bumps a lot more so you may want to try and stick with rubber at the cost of longevity.

All that aside, Superlift has always made a good product and I'm sure the Skyjacker Softride kits are built well and ride decent. Again, stay away from the dual shock setups and blocks under the leafs. You could also try and call up Deaver Spring Co. and have them walk you through a custom set of leafs.
