Part #: KTA320

Overview

The Whiteline Front Upper Control Arm is a specially designed upgrade for Chevrolet Silverado 1500 and GMC Sierra 1500 trucks from 2009 to 2018. If you've lifted your truck between 2 and 4 inches, you may have encountered issues with wheel alignment, camber, caster, and ball joint articulation. These problems can affect your vehicle's handling, tire wear, and overall drivability. Whiteline's all-in-one solution addresses these challenges by providing a high-quality, adjustable control arm that restores proper alignment angles and improves articulation.

Designed for enthusiasts who want to maintain optimal suspension geometry after lifting, this control arm enhances your truck's off-road capability and on-road stability. Whether you're upgrading for off-road adventures, towing, or simply want a more aggressive stance, the Whiteline UCA ensures your vehicle performs reliably and handles confidently in all conditions.
