2019-2024 GM 1500 Billet Upper Control Arm Delta Joint Kit (ICO78720DJ)

The ICON Vehicle Dynamics Billet Upper Control Arm (UCA) Kit is the ultimate alignment and performance solution for the 2019-2025 Chevrolet Silverado/GMC Sierra 1500 and 2021-2025 GM SUVs. Constructed from CNC-machined 6061 billet aluminum, these arms offer a superior strength-to-weight ratio and feature a signature double adjuster sleeve that allows for caster and camber adjustments to be made while the arms are still on the vehicle. Equipped with ICON’s patented Delta Joint, this kit provides the high-angle articulation required to maximize wheel travel and performance on lifted GM trucks.

Features

• CNC-Machined Billet Construction: Manufactured from 6061 billet aluminum for extreme strength, weight savings, and a premium aesthetic.
• Patented Delta Joint: A heavy-duty, high-angle ball joint that delivers the performance of a uniball with the longevity of a fully sealed and greasable factory joint.
• On-Vehicle Adjustability: Features ICON’s double adjuster sleeves and 7/8-inch FK Rod Ends, allowing for precise caster and camber tuning without removing the arms from the truck.
• Improved Geometry: Corrects front-end geometry and component clearance, which is essential for proper alignment and handling on vehicles with 1.5 to 3.5 inches of lift.
• Weather Resistant Design: The Delta Joint features a zinc-plated housing and a tough grease seal to protect internal metal-on-metal components from the elements.
• O-Ring Sealed Cap: Includes a built-in dust cover cap to further protect the Delta Joint from road salt, moisture, and debris.
