Control Arms

Control Arms

Control arms are the key suspension linkages that connect the wheel hub and knuckle assembly to the vehicle frame, controlling wheel travel through both compression and droop cycles. Worn OEM control arms with loose ball joints or deteriorated bushings cause vague steering, tire wear, and handling inconsistency that only go away with replacement or upgrade.Popular UpgradesTubular steel upper control arms for lifted trucks and SUVs are the most popular upgrade in the control arm category, correcting the geometry compromised by a suspension lift and restoring proper caster angle and ball joint centering. Adjustable upper control arms allow alignment angles like caster and camber to be dialed in precisely after a lift or lowering modification.
