2001-10 2&4WD Chevy Silverado, GMC Sierra 2500HD, 3500 0-2.5" Stage 3 Tubular UCA Leveling Kit

The massive spring rate of the torsion bar system on the Silverado and Sierra 2500HD or 3500 requires significant shock damping. ICON has developed vehicle specific front and rear shocks for a compliant street ride with the ability to maintain this quality ride when driving to construction sites or a favorite off-road location. Front and rear shocks are adjustable from 0" to 2.5" of lift.

The ICON Stage 3 system features front and rear VS 2.5 Series Piggyback reservoir shocks. The reservoir increases the length of time of consistent damping regardless of the driving situation. This keeps the shocks operating at a cooler temperature during heavy usage. These shocks are the key to gaining optimal ride quality for these hard working trucks.

Replace the weak factory ball joints on your Silverado or Sierra 2500HD, 3500HD with the ICON tubular uniball upper control arm system. Factory ball joints limit suspension travel and are considerably weaker than the ICON upgrade option. These use 1" PTFE lined uniballs combined with 17-4 stainless taper pin adapters that will increase the upper arms misalignment. What this does is eliminate factory ball joint bind and allows for smooth and clean wheel travel.
