Upgrade your heavy-duty GM truck's front suspension with the ICON Tubular Upper Control Arm Delta Joint Kit. Engineered to solve the common trade-offs between daily-drive reliability and off-road performance, these arms replace restrictive factory units with high-strength 1026 DOM steel tubing. The built-in caster correction helps maintain proper alignment on leveled or lifted applications, improving steering feel and tire wear.

The centerpiece of this kit is the patented ICON Delta Joint. This heavy-duty, high-angle ball joint provides the extreme articulation of a traditional uniball while maintaining the longevity and weather sealing of a standard ball joint. Its zinc-plated housing and tough grease seal protect internal components from road salt and debris, ensuring quiet, reliable operation in harsh environments. Every arm is finished in a durable semi-gloss black powder coat for long-term corrosion resistance.
