FOX Billet Upper Control Arms – Heavy-Duty Suspension Upgrade for 2020–2025 LM2 and LZ0 Platforms

Description

Fits: 2020 thru 2025 Chevy Silverado/GMC Sierra 1500 LM2/LZ0 Duramax Diesel

The Upper Control Arms (UCA) are considered the first step when building a mid-travel truck, to unlock the vehicles off-road capability through tough terrain. Fox engineers spent time evaluating suspension geometry and optimized the UCAs specifically for the intended vehicle. FOX UCAs provide the necessary correction when lifting a vehicle to maintain the alignment while maximizing droop travel for more articulation off-road. Additional caster helps reduce wander at high-speed for more confidence behind the wheel. You’ll notice a precise comfortable ride on rougher roads and trails.

Features:

• FOX upper control arms are CNC machined in the USA from T6061 billet aluminum. Type II anodization offers superior corrosion resistance and feature a laser etched FOX logo
• 1.25″ uniballs are comprised of a hard chrome plated ball and low carbon steel race to increase service life. A PTFE liner mitigates noise to keep the ride comfortable
• The 3/4″ chromoly heim joints are fully adjustable allowing for fine tuning of caster and camber. The Kevlar fiber reinforced PTFE liner to prevent binding and long-lasting precision
• Stainless-steel taper misalignment spacers and 12-point bolts at the steering knuckle ensure a reliable and precise fit. Bolt-on the UCAs without any modification to the vehicle chassis
