Hi Trevor ,the gas shocks normally hav a nob on the bottom of the shocker to adjust the rebound you will here it click as you turn it ,but to be honest I think the springs extreme use were quite hard so not sure just how soft you will get it without changing the springs ,they are normally adjustable platforms too,which means you can adjust the spring height up and down ,adjusting it down ie lowering the car will also soften the ride providing the shocker has enough travel left , hope this helps jd ,ps the spanner for adjusting the platform is called a c spanner ,
