Fits select 1964-1967 Buick, Chevrolet, Oldsmobile, and Pontiac A-Body vehicles including Chevelle, El Camino, GTO, LeMans, Cutlass, 442, and Skylark.

QA1 Upper Adjustable Trailing Arms are designed to provide the precision tuning required for high-performance street and track applications. These arms allow you to adjust the rear wheelbase and pinion angle without removing the components from the vehicle—simply loosen the jam nuts to make your adjustments. This capability is essential for correcting driveline angles and optimizing traction for a more predictable and better-handling car.

Built for maximum durability, these arms feature a zinc-plated and anodized finish for superior corrosion resistance. To eliminate suspension bind, the chassis end utilizes a spherical ball or rod end assembly with UHMW polyethylene bushings, allowing for smoother suspension travel compared to factory rubber. The set also includes fluted, greasable polyurethane bushings to replace soft OE differential bushings, further reducing flex and keeping your tires planted.
