Description
High-Performance Suspension Upgrade. The Fabtech Uniball Upper Control Arms for 0 to 6-inch lift provide a robust replacement for factory ball joint arms, designed to strengthen the front suspension during aggressive off-road driving. They improve caster by one degree, enhancing alignment and handling when using oversized tires.
Construction and Appearance. These arms are made from 1.50-inch outer diameter, 0.120-inch wall 4130 chromoly tubing to minimize flex. They feature 1-inch diameter stainless steel FK uniballs with 17-4 stainless steel heat-treated pins that fit factory spindle tapers without modification. Large urethane pivot bushings reduce chassis noise and vibration, while a billet uniball cap provides protection against dirt and debris.
Installation. This product installs as a direct replacement for factory arms with no drilling required, allowing an easy return to stock hardware if needed.
Warranty. Includes a limited lifetime warranty.
Application. Precisely engineered to fit 2020–2026 4WD Sierra 2500 HD models.
