This Icon Vehicle Dynamics K77102 (Stage 3) 0 to 2 inch suspension system for the Chevy Silverado 2500HD / Silverado 3500HD is a premium kit that will allow adjustment of your factory torsion bar keys to allow clearance for large diameter tires, while also greatly improving suspension performance. Icon systems are engineered to increase wheel travel and your vehicle's damping for excellent on and off-road control and superior ride quality.

Icon 2.5 VS PB Shocks

The Icon 2.5 VS (vehicle specific valving) PB (piggyback reservoir) shocks are a superior dampening upgrade. These nitro gas monotube shocks use a large 2.5 inch diameter body made of 6061 aluminum allowing for superior dissipation of heat and resistance to corrosion while looking great. A piggyback reservoir is added for increased damping, ideal for off-road conditions. Polyurethane bushings and a 7/8 inch chrome plated steel shaft are also featured.

Icon Tubular Upper Control Arms with Delta Joints

Icon's tubular steel upper control arms are constructed from CNC bent 1026 DOM steel tubing for excellent strength. Featured are the amazing Delta Joints that combine the durability of a ball joint with the performance of a uni-ball. Ideal when paired with Icon coilovers to increase wheel travel which translates into better suspension performance and ride quality. Engineered with built-in caster correction for optimal alignment specs, serviceable dual stage poly bushings and a black semi-gloss powder coat finish for durability.
