The ICON 20-26 GM 2500/3500 HD Billet Upper Control Arm (UCA) with Delta Joint Pro HD is a high-performance suspension component designed for heavy-duty trucks. It features ICON's innovative Delta Joint Pro HD articulation joint, which combines the durability of factory-style ball joints with enhanced performance and strength surpassing traditional motorsports joints. The joint is rebuildable and serviceable, allowing for easy inspection and replacement of individual components. Its larger ball with 56% more bearing surface, improved lubrication sealing, and a full 90-degree articulation range provide maximum bind-free suspension movement. Built with chromoly balls and shafts hardened to Rockwell C 55, and equipped with graphite-impregnated sintered metal races, this UCA offers superior durability and load capacity for off-road and heavy-duty applications.

Designed for 2020 to 2026 model years of GM 2500 and 3500 HD trucks, this kit is compatible with trucks equipped with the respective chassis and suspension setups. It is intended for off-road, heavy-duty, and towing use, providing increased articulation and durability for extreme conditions. The kit includes the billet upper control arms and Delta Joint Pro HD components, serving as a direct replacement upgrade for factory UCAs. Installation is straightforward for those familiar with suspension work, and the components are optimized to handle the demands of maximum wheel travel and off-road abuse, ensuring long-lasting performance in demanding environments.

Overview

ICON suspension components with the all-new Delta Joint Pro HD represent the state of the art in off-road performance and durability. Delta Joint Pro HD is ICON's innovative new suspension articulation joint which combines the durability and longevity of factory style ball joints with performance and strength that exceeds traditional motorsports-style ball joints. The Delta Joint Pro HD features a rebuildable, serviceable design in which any component may be removed, inspected and replaced without having to purchase a whole new joint. Strength and durability are improved by using a larger ball with 56% more bearing surface than our standard Delta Joint, along with improved lubrication sealing. But improved performance is at the heart of the Delta Joint Pro, with a full 90 degrees of articulation, from one extreme to the other. This represents a 14% improvement in range of motion, over the highly capable original Delta Joint, allowing for maximum bind-free suspension movement through the complete range of travel. The Delta Joint Pro HD is built to take the abuse, with a chromoly ball and shaft that has a bearing surface hardened to Rockwell C 55. The replaceable races are made of graphite-impregnated sintered metal, machined to the finest tolerance to provide a flawless, metal-to-metal bearing interface. We also redesigned the lubrication system, with lubricant channels that distribute grease more efficiently without extending past the bearing seal. Optimized for heavy duty truck applications, the Delta Joint Pro HD differs from a Delta Joint Pro for other applications with its slotted housing that adds additional support to the lower bearing race. This extra support significantly increases pull out strength beyond that of a standard Delta Joint Pro, ensuring the ball joint can handle the extreme loads found at the maximum limits of wheel travel on HD truck applications. All while maintaining the same 90-degree range of motion.
