When it comes to fine-tuning your 1968-1972 GM A-body, QA1's Adjustable Upper Trailing Arms (rear control arms) are a game-changer. Whether you're driving a Chevelle, Malibu, or GTO, these control arms are built to improve your car's performance and durability with ease. PINION ANGLE ADJUSTMENT FOR LOWERED VEHICLES If you've lowered your A-body, 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. EASY BOLT-IN INSTALLATION The bolt-in installation makes this upgrade hassle-free, allowing you to quickly and easily improve your vehicle’s suspension without extensive modifications. FEATURES & BENEFITS • High-strength, low-bind construction for reliable performance. • Aluminum hex design allows for easy on-the-car pinion angle adjustments. • Reduces friction for smoother suspension travel. • High-quality polyurethane bushings replace the softer OE ones for improved stability. • Easy bolt-in installation without complicated modifications needed.

Manufacturer's Warranty — QA1
QA1 warrants this product to the original purchaser to be free from defects in material and workmanship for one year from the date of sale. A separate limited lifetime warranty covers only QA1's select shock and strut lines (Stocker Star, Proma Star, Ultra Ride and Aluma Matic) and requires registration at QA1.net/Warranty within 30 days of purchase. QA1 makes no other warranty, express or implied. Coverage does not apply where the defect results from improper or abnormal use, negligence, vehicle accident, incorrect installation or maintenance, or where the product has been repaired or altered in any way. QA1's liability is limited to repair or replacement of the defective product at its option; consequential and incidental damages are excluded. A claim needs an RMA number issued by QA1 — tag each item with the part number and a description of the defect — and the customer pays shipping to QA1 for inspection.
Warranty terms are set by the manufacturer and may change. Full details and claims are handled directly by QA1. Contact us if you need help with a warranty claim.
