Product Description

The QA1 5297 Adjustable Upper Trailing Arm is engineered for 1965-1968 Chevrolet full-size B-Body vehicles equipped with the longer factory upper trailing arm. Its heavy-duty tubular steel construction and low-bind polyurethane bushings provide improved suspension articulation, enhanced durability, and more consistent rear axle control compared to worn factory components.

The integrated aluminum hex adjuster allows precise pinion angle adjustments without removing the arm from the vehicle, making it an excellent choice for lowered street cars and performance applications. By optimizing driveline geometry and reducing suspension bind, the QA1 5297 helps improve traction, minimize wheel hop, and deliver more predictable handling while retaining a straightforward bolt-on installation using factory mounting locations.
