Icon Vehicle Dynamics K78361 Stage 1 Suspension Lift Kit Lift 2-3.5" Chevrolet Silverado/GMC Sierra 2500/3500 AT4/AT4X/ZR2 20-26

ICON Stage 1 Suspension System for 2020-2026 Chevrolet Silverado 2500/3500 HD & GMC Sierra 2500/3500 HD

The ICON Stage 1 suspension system is engineered for 2020–2026 3/4- and 1-ton Chevrolet Silverado and GMC Sierra trucks. The complete bolt-on kit combines vehicle-specific tuned internal-reservoir shocks, billet aluminum upper control arms, and forged torsion keys to increase front lift, improve front-end geometry, and enhance ride quality and suspension travel while retaining working capability.

• Front lift adjustability: 2–3.5" of front lift height over stock (vehicle- and variant-dependent).
• Shocks: ICON V.S. 2.0 HD Series front and rear shocks with internal reservoirs and corrosion-resistant hard anodized aluminum bodies for superior damping and control.
• Upper control arms: Billet aluminum Delta Joint Pro HD UCAs provide corrected front-end geometry, increased camber/caster adjustment, improved component clearance, and greater wheel travel; Delta Joint Pro HD is serviceable and rebuildable.
• Torsion keys: Forged steel torsion keys install on factory torsion bars to allow front lift and a level stance for larger wheel and tire fitment.
• Increased travel: Approximately 3" of additional front wheel travel over stock when paired with extended travel front shocks.
• Construction: 6061 aircraft-grade CNC machined aluminum components and robust HD shock internals for durability.
• Installation: 100% bolt-on system — no drilling, cutting, or welding required.
• Serviceability: Shocks are fully serviceable.
• Towing and ride: Improved ride quality over stock while maintaining towing capability.
