Level up your 2020-2026 GM HD with this complete ICON suspension system. 2-3.5" of lift gets you the clearance for bigger tires without killing your ride quality. Everything in this kit is tuned to work together — springs, shocks, and hardware designed as a complete package.

Features
- Adjustable for 2-3.5" of front lift height over stock
- Vehicle specific tuned 2.5 Aluminum Series remote reservoir front and piggyback reservoir rear shocks for superior shock damping and control
- ICON's CDE Valve technology allows for in vehicle adjustment of compression damping settings and active adjustment via the ICON Intelligent Control (IIC)
- ICON Intelligent Control (IIC) uses onboard sensors to monitor G-forces and movement of vehicle chassis along with user defined settings to actively make near instantaneous compression damping changes
- Improved ride quality and suspension performance over stock
- Billet aluminum Delta Joint Pro HD UCAs allow for additional caster/camber adjustment
- Forged steel torsion keys
- Front wheel travel increase of approximately 3" over stock
- Rear leaf springs lower spring rate and increase distance to overload engagement compared to stock to greatly improve rear ride quality
