5297 Upper Adjustable 12.81in., GM B-Body, 65-67

When it comes to fine-tuning your 1965-1967 Chevy Full Size, QA1's Adjustable Upper Trailing Arms (rear control arms) are a game-changer.

PINION ANGLE ADJUSTMENT FOR LOWERED VEHICLES

If you've lowered your car, adjusting the pinion angle is essential to keep everything running smoothly. Our Rear Upper Trailing Arms make this adjustment simple, thanks to an aluminum hex design that lets you make adjustments right on the car. Setting the pinion angle correctly not only prevents unnecessary wear and tear on your drivetrain but also helps avoid issues like wheel hop. With everything properly aligned, your car will ride better and perform at its best.

REDUCE REAR SUSPENSION BIND

Our trailing arms are designed to cut down on suspension bind, which means your car’s rear suspension will move more freely. The result? A smoother ride and better traction, giving you more consistent performance every time you hit the road.

THOUGHTFUL DESIGN

Experience the benefits of thoughtful design with this easy bolt-in upgrade. Engineered for durability and performance, these components replace the soft OE differential bushings with high-quality polyurethane bushings, enhancing stability and responsiveness.
