Any of the 2.0 body OE shocks from Fox, Icon etc should give you a better ride than stock. Check with Carli or Thuren as they can give you custom valved 2.0 shocks from King, Fox etc and theyre not much more expensive than conventional shocks either. I think cheapest set from Carli are Fox 2.0 custom valved for your 2500 and they start at $624 for all 4 shocks. It starts getting expensive as you add lift stuff,coil springs steering components etc.
