Icon Vehicle Dynamics 78732 Front Shock System W/Upper Control Arm Lift 0-2" Chevrolet Silverado/GMC Sierra 2500/3500 20-26

ICON Vehicle Dynamics

Take the performance of your 2020–2026 GM HD truck to new levels with the ICON Vehicle Dynamics Delta Joint billet upper control arm kit. CNC-machined 6061 billet aluminum combines light weight with high strength. High-angle heim joints provide precise, smooth articulation and allow additional camber and caster adjustment for optimal alignment and confident handling. When paired with ICON 2.5 Series shock absorbers, these upper control arms increase wheel travel for superior performance and ride quality.

The kit features ICON's patented Delta Joint: a heavy-duty, high-angle ball joint that blends the durability of a traditional ball joint with the articulation of a uniball. A corrosion-resistant housing and a durable grease seal protect the joint from contaminants. Metal-on-metal construction and a greaseable design increase longevity while enabling quiet, reliable operation and greater angularity than a typical ball joint.

Upper control arms are supplied as part of a complete system with ICON Vehicle Specific (V.S.) 2.5 Series shocks. These shocks are configured specifically for each application in both length and damping tune, and are designed to deliver strong off-road performance while maintaining a smooth on-road ride.
