ICON 2020+ Chevrolet Silverado/GMC Sierra 2500/3500 HD 2-3.5" Lift Billet Suspension System

ICON offers a comprehensive lineup of preconfigured Complete Suspension Systems for 2020-26 GM 2500/3500. Below is a list of all 6 "Stages" featuring 2.0 and 2.5 VS shocks, along with a brief description of how each Stage builds or improves on the features of the previous stage.

IVD-K78361 (Stage 1)

Stage 1 is ICON's basic Performance Suspension System for 2020-26 GM 2500/3500 trucks. The included Torsion Keys yield 2 to 3.5 inches of front suspension lift. The HD 2.0 VS front and rear shocks engineered specifically for the increased suspension suspension height on these heavy duty trucks. The kit is rounded out with ICON Billet Upper Control Arms featuring the patented Delta Joint and on-vehicle adjustability.

IVD-K78362 / IVD-K78362L (Stage 2)

Stage 2 takes suspension performance up a notch by adding remote reservoirs to the front and rear shocks. Reservoirs increase fluid volume and heat dissipation to improve shock performance for prolonged use over rough terrain. Also, beginning with Stage 2, ICON performance rear leaf springs are optional, providing superior rear suspension travel and performance.

IVD-K78363 / IVD-K78363L (Stage 3)

Stage 5 steps up to ICON 2.5 VS shocks with remote reservoirs. These shocks provide increased fluid volume and piston diameter versus ICON's 2.0 series shocks, improving damping performance and fluid longevity. These shocks also feature an internal Bump Zone to increase damping force by 20% as shock travel approaches full compression.

IVD-K78364 / IVD-K78364L (Stage 4)

Performance adjustability takes center stage at Stage 4, with ICON's exclusive Compression Damping Control Valve built into each shock. CDCV provides manual compression damping adjustability using an easy-to-grab adjustment knob located on the shock reservoir. Adjusting fluid control under compression allows for fine-tuning shock performance to optimize for any driving conditions.

IVD-K78365 / IVD-K78365L (Stage 5)

Take the next step up in shock tune adjustability with Stage 5, featuring ICON's proprietary Compression Damping Dual Speed valves on each shock. CDXS allows for independent control of fluid flow under compression, for both high-speed and low-speed fluid circuits. The result is a ride and performance perfectly dialed in for any terrain.

IVD-K78366 / IVD-K78366L (Stage 6)

ICON's incredible Compression Damping Electronic Valve technology joins the lineup at Stage 6. CDEV with IIC ingeniously reacts to terrain and driving conditions almost instantaneously to adjust compression damping on the fly. The result is flawless performance where the vehicle's suspension adapts automatically to changing conditions in microseconds. All of this can be set up, controlled and monitored through the integrated app on your phone for a state-of-the-art driving experience.
