2019-2024 GM 1500 Tubular Upper Control Arm Delta Joint Kit (ICO78620DJ)

The ICON Vehicle Dynamics Tubular Upper Control Arm (UCA) Kit is an essential performance upgrade for the 2019-2025 Chevrolet Silverado/GMC Sierra 1500 and 2021-2025 GM SUVs. These arms are engineered to correct front-end geometry and caster on lifted or leveled vehicles, ensuring the truck can be properly aligned to maintain factory-like handling and straight-line stability. By replacing the factory components, these UCAs unlock the potential for significantly increased wheel travel when paired with ICON 2.5 Series coilovers.

Features

• Patented Delta Joint: A heavy-duty, high-angle ball joint that combines the durability of a sealed ball joint with the articulation performance of a racing uniball.
• Weather Resistant Design: Features a zinc-plated housing and a tough grease seal to protect the internal metal-on-metal construction from the elements and road debris.
• Built-In Caster Correction: Engineered to provide the additional positive caster required for optimal alignment specifications on vehicles with front suspension lifts.
• Heavy-Duty Construction: Constructed from CNC-bent 1026 DOM steel tubing with a semi-gloss black powder coat finish for maximum strength and corrosion resistance.
• Serviceable Components: Equipped with dual-stage polyurethane bushings and a greasable Delta Joint for long-term reliability and quiet, noise-free operation.
• Increased Wheel Travel: Specifically designed to eliminate component bind, allowing the suspension to cycle through its full range of travel when used with ICON performance coilovers.
