Product Description

The ICON 78720DJ Billet Upper Control Arm Kit with Delta Joints is a premium front suspension upgrade designed for **2019-2023 GM 1500 trucks and SUVs**, including **Chevrolet Silverado 1500, GMC Sierra 1500, Chevrolet Tahoe/Suburban, and GMC Yukon/Yukon XL**. Built from CNC-machined 6061 aluminum, these arms replace the factory upper control arms with a stronger, lighter design that improves suspension articulation and performance, especially on lifted vehicles. The patented Delta Joint combines the durability of a ball joint with the articulation of uniball setups while shielding the internals from dirt and moisture with sealed dust covers.

Featuring adjustable camber and caster via ICON's double adjuster sleeves, the 78720DJ kit lets you fine-tune alignment after lift modifications. PTFE-lined 7/8" FK rod ends provide smooth, responsive motion throughout the suspension travel. These arms support up to approximately **3.5" of front lift** on most pickup variants and are engineered with vehicle-specific taper pins for OE-like fitment. They are **not compatible** with Silverado ZR2, Sierra AT4X, Adaptive Ride Control (ARC), or torsion bar front spring models. Installation hardware is included for a complete upgrade.
