ICON 2020-2026 Chevrolet Silverado/GMC Sierra 2500/3500 HD, Front Upper, Billet Control Arm Kit, w/ Delta Joint Pro HD

This ICON billet aluminum upper control arm kit is designed to improve the overall performance of the 2020-2026 Chevrolet Silverado 2500 HD/3500 HD and 2020-2026 GMC Sierra 2500 HD/3500 HD with corrected front-end geometry, increased camber and caster adjustment, and improved suspension component clearance. Constructed of CNC-machined 6061 billet aluminum utilizing a hybrid H-beam cross-section that is lightweight and resists bending forces better than tubular arms. Replacing the OE ball joint with the all-new, serviceable, and rebuildable ICON Delta Joint Pro HD allows for full bump and droop travel of the front suspension while eliminating bind. FK Rod End 3/4” Heim joints provide precise and smooth function throughout the range of travel, while ICON’s signature double adjuster sleeve allows for on-vehicle camber and caster adjustment. Included with all components and hardware necessary for a complete install, these billet UCAs are the perfect front-end upgrade for the 2020-2026 Chevrolet Silverado 2500 HD/3500 HD and 2020-2026 GMC Sierra 2500 HD/3500 HD.

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 and 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.
