QA1 52540 Race Lower Control Arm Kit | 79-93 Mustang

Upgrade your 1979-1993 Ford Mustang's front suspension with QA1 Race Lower Control Arms, engineered for lightweight performance, increased adjustability and precise suspension movement. Designed for performance-focused Fox Body builds using coilover struts, these tubular control arms give you greater control over front suspension setup without sacrificing durability.

ON-THE-CAR ADJUSTABILITY

Dial in your Mustang's front suspension without repeatedly removing the control arms. QA1's unique eccentric adjustment sleeve allows camber and track width changes with the control arms installed, giving you greater flexibility when setting up the car for your combination.

Control arm length can be adjusted +/- 1/8 inch from the factory length, with up to 1/2 inch of track width adjustment available.

BUILT FOR RACE-FOCUSED PERFORMANCE

Weighing less than 8 pounds per arm, QA1 Race Lower Control Arms help reduce front-end weight while providing the strength needed for demanding performance use.

Forged ball joint housings add strength and durability where it matters, while low-friction, rebuildable and greaseable ball joints promote smooth suspension movement and make long-term service easier.

ULTRA-LOW-FRICTION COMPOSITE BUSHINGS

Instead of traditional rubber or polyurethane bushings, these race control arms use QA1's ultra-low-friction composite bushings. Their bind-free design allows the suspension to move more freely while minimizing unwanted deflection for more responsive and predictable suspension behavior.

BOLT-IN FOX BODY UPGRADE

Designed specifically for 1979-1993 Fox Body Mustangs, these control arms are compatible with both factory and QA1 K-members. Adapters for SN95 spindles are included, providing additional flexibility when building or upgrading your Mustang's front suspension.
