Icon Vehicle Dynamics K73064T Stage 4 Suspension Lift Kit Lift 1.5-3.5" Chevrolet Silverado/GMC Sierra 1500 AT4 19-26

ICON Vehicle Dynamics

Stage 4 suspension system engineered for 2019–2026 Chevrolet Silverado 1500 and GMC Sierra 1500 to dramatically improve on- and off-road ride quality, wheel travel and vehicle control. The system uses ICON 2.5 Series remote-reservoir CDCV coilovers up front and 2.5 Series piggyback rear shocks with remote reservoirs for improved cooling, consistent damping and extended service life. Tubular steel upper control arms with ICON’s patented Delta Joint increase angularity, durability and longevity compared to conventional joints.

• Adjustable front lift: 1.5"–3.5" height adjustment (coilovers)
• Improved wheel travel: Up to 35% increase in front wheel travel over stock
• Shock construction: 2.5 Series coilovers feature corrosion-resistant CAD-plated bodies and 7/8" shafts; 2.5 Aluminum Series rear shocks use one-piece impact-extruded aluminum cylinders
• Remote reservoirs: 7.5" aluminum reservoirs for increased oil/nitrogen volume and consistent damping under heat
• Adjustable damping: Easy-to-adjust CDC Valve (Compression Damping Control) for terrain and load tuning
• Upper control arms: Tubular steel arms with patented Delta Joint combining ball-joint weather resistance and uniball angularity; greaseable and zinc-plated for corrosion resistance
• Hardware & serviceability: FK rod end bearings, fully rebuildable and revalvable shocks
• Fitment: Designed for 2WD and 4WD applications with coil-front-spring models
• Installation: Direct bolt-in design for straightforward installation
• Warranty: Lifetime guarantee against fabricated component breakage or manufacturer defect

Technical highlights

• OEM wheels and tires remain compatible
• Recommended wheel sizes: 17x8.5, 18x9, 20x9 (0mm offset suggested)
• Recommended tire fitment (may require minor fender trimming): Silverado — up to 35x12.50; Sierra — up to 34x12.00

Notes:

• These systems are to be used with aftermarket upper control arms only.
• Shocks are fully serviceable. Coilover heights indicated are for a stock-equipped vehicle.
• Minor trimming may be required for the recommended tire sizes.
• Requires recalibration of Advanced Driver Assistance Systems (ADAS) after installation.
• Most gasoline-equipped Silverado and Sierra submodels will have a front lift range of 1.5"–3.5" over stock; Trail Boss and AT4 models will have a front lift range of 0"–1.5".
• Most diesel-equipped Silverado and Sierra submodels will have a front lift range of 1"–3" over stock; Trail Boss and AT4 models will have a front lift range of 0"–1".
• Models equipped with Adaptive Ride Control may require additional interface parts for proper integration.
• Only fits models equipped with coil front springs; not compatible with 4-cylinder engine models, Silverado 1500 ZR2 or Sierra 1500 AT4X sub-models.
• Included rear shocks are compatible with 0"–2" of rear lift on most models; not recommended with additional rear lift on Silverado 1500 Trail Boss and Sierra 1500 AT4.
• For Trail Boss and AT4 models, replacing OE rear blocks with 1" rear blocks is recommended if a level stance is desired.
