What Are Adjustable Control Arms and Why Your Lifted Truck Needs Them
Published: July 2026 | By: Apoc Industries Team
When you lift your truck, the factory suspension geometry changes. This often leads to poor handling, accelerated tire wear, and driveline vibrations. Adjustable control arms are one of the most important upgrades you can make to restore — and even improve — your lifted truck’s performance.
What Are Adjustable Control Arms?
Control arms connect the chassis to the axle or wheel assembly. Adjustable versions feature heim joints or threaded ends that let you change length for precise adjustments. This corrects caster, camber, and pinion angles thrown off by lift kits or lift blocks.
