QA1 78-88 Gm A-Body/G-Body Lower Trailing Arms

QA1 sets the standard for superior suspension components with its line of trailing arms designed for optimum performance and durability. Whether you choose upper tubular, lower boxed, adjustable, or tubular trailing arms, QA1 ensures that your vehicle's suspension system operates at its best.

All upper tubular and lower boxed trailing arms feature polyurethane bushings on both ends. For upper adjustable and lower tubular trailing arms, QA1 employs a spherical ball or rod end assembly on the chassis end. This strategic design eliminates bushing bind, allowing the suspension to move smoothly for enhanced control. The result is a car with tires firmly planted on the ground, delivering improved traction and predictable, better handling.

To withstand the rigors of the road and ensure a long-lasting finish, tubular and boxed trailing arms are powder-coated in a sleek gloss black. Adjustable arms, on the other hand, are zinc plated and anodized for durability and corrosion resistance.

QA1's Boxed Trailing Arms are constructed from 0.120'' wall cold-rolled steel tubing, offering maximum strength and eliminating flex. These arms feature fluted, greasable polyurethane bushings, surpassing stock rubber bushings in performance.

For Tubular Trailing Arms, QA1 uses 1-1/4'' diameter, 0.120'' wall steel tubing, providing increased strength with the added advantage of lighter weight. Like the boxed trailing arms, these tubular arms incorporate fluted, greasable polyurethane bushings for superior performance.

The Heavy-Duty Adjustable Trailing Arms simplify rear suspension adjustments for optimal handling and traction. With the ability to adjust the pinion angle without removing the arms, these trailing arms offer convenience and precision. They replace OE differential bushings with polyurethane for added durability and utilize a spherical ball or rod end assembly with UHMW polyethylene bushings on the chassis end, promoting free movement and eliminating bushing bind. All QA1 trailing arms are sold in pairs, ensuring a comprehensive upgrade for your vehicle's suspension system. Choose QA1 for a combination of quality, performance, and longevity in your suspension components.
