Product Description

ICON 2020-2026 GM 2500/3500 HD, 0-2" Lift, Stage 2 Suspension System, Billet (K78352)

The ICON Vehicle Dynamics Stage 2 Suspension System is a premium leveling and performance upgrade engineered for 2020–2026 GM 2500HD and 3500HD trucks. Designed to improve ride quality, increase wheel travel, and enhance suspension control, this system features ICON 2.5 Series remote reservoir shocks and billet aluminum upper control arms with Delta Joint technology. Built for heavy-duty towing, daily driving, and off-road use, this system delivers improved damping consistency and enhanced durability while maintaining factory towing capability. 

0–2” Adjustable Lift Height for Level Stance

This system provides adjustable lift height from 0” to 2” over stock, allowing users to level the front of the vehicle and improve overall stance. The additional clearance supports larger tire fitment while maintaining proper suspension geometry. 

2.5 Series Remote Reservoir Shocks

Vehicle-specific tuned ICON 2.5 Aluminum Series shocks feature remote reservoirs that increase oil capacity and reduce heat buildup. This design ensures consistent damping performance under heavy loads, towing conditions, and rough terrain. 

Billet Upper Control Arms with Delta Joint Technology

The included CNC-machined billet aluminum upper control arms feature ICON’s patented Delta Joint, combining the strength of a traditional ball joint with the articulation of a uniball. This design improves suspension geometry, increases alignment adjustability, and enhances durability in demanding environments.

Improved Ride Quality Without Sacrificing Towing Capacity

The Stage 2 system is engineered to enhance ride comfort and suspension control while maintaining the heavy-duty capability expected from ¾-ton and 1-ton trucks. This makes it ideal for work vehicles and tow rigs that require dependable performance. 

Increased Wheel Travel for Enhanced Performance

Extended travel shock design and optimized suspension geometry increase wheel travel by approximately 2 inches over stock, improving traction and stability when driving on uneven terrain or rough job sites.

Durable Aluminum Components for Long-Term Reliability

High-quality materials including anodized aluminum shock bodies and CNC-machined billet components provide corrosion resistance and long-lasting performance in harsh environments.

Simple Bolt-On Installation

This Stage 2 suspension system installs as a complete bolt-on solution requiring no cutting, drilling, or welding. The design allows straightforward installation while maintaining factory mounting integrity.
