2001-2010 GM HD Tubular Upper Control Arm Delta Joint Kit (ICO78550DJ)

The ICON Vehicle Dynamics Tubular Upper Control Arm (UCA) Kit is a critical suspension upgrade for the 2001-2010 Chevrolet and GMC 2500HD / 3500HD. These arms are engineered to correct front-end geometry and caster after lifting or leveling, ensuring the vehicle can be properly aligned to maintain factory-like handling. This kit replaces the weak factory ball joints with ICON’s patented Delta Joint, providing significantly more articulation and nearly 50% more wheel travel when paired with ICON performance shocks.

Features

• Patented Delta Joint: A heavy-duty, high-angle ball joint that combines the durability and weather-sealing of a standard ball joint with the extreme articulation of a racing uniball.
• Robust Protection: Features a zinc-plated housing and a tough grease seal to keep contaminants out, alongside a metal-on-metal design for long-term reliability.
• Built-In Caster Correction: Engineered to provide additional positive caster, which is necessary to maintain straight-line stability and proper steering feel on lifted trucks.
• Superior Construction: Fabricated from CNC-bent 1026 DOM steel tubing with CNC-machined bushing housings for maximum strength and precision.
• Serviceable Bushings: Equipped with dual-stage polyurethane bushings that are greasable for quiet, bind-free operation.
• Durable Finish: Protected by a multi-stage, semi-gloss black powder coat finish for superior corrosion resistance.

Notes

• Specifically fits 2001-2010 Chevrolet Silverado 2500HD / 3500HD and GMC Sierra 2500HD / 3500HD 2WD and 4WD models.
• Required for vehicles using extended travel 2.5 Series shocks to prevent the upper control arm from limiting down-travel.
• Compatible with factory wheels and tires.
• Recommended aftermarket wheels: 17-inch or larger wheels with a maximum 5.00-inch backspace.
• Delta Joint features a 5-year limited warranty when used as part of a complete ICON suspension system.
