Right now I have a 6" Pro Comp Lift Stage 1 on a Double Cab SR5 (TSS edition). I have 305/55/20 Nitto Trail Grapplers on the TSS wheels. When I bought the truck new in 2006, the ride was marginal. You feel every bump on a concrete road. Black top is alot smoother. After I lifted it, it is still bumpy. Would the 5100's fix this and do they ride better than the base model shocks? If not , maybe someone can give me some input on the Pro comp coilovers or Rad flo's.
