The QA1 Upper Non-Adjustable Tubular Trailing Arms are high-performance suspension components designed for classic GM G-Body and A-Body vehicles. Constructed from durable tubular steel, these trailing arms provide enhanced strength and rigidity to improve handling and stability. Their non-adjustable design ensures a straightforward installation while maintaining precise geometry. These arms are engineered to withstand the stresses of spirited driving and track use, offering increased durability and consistent performance over stock components. By replacing factory trailing arms with these QA1 units, enthusiasts can achieve improved suspension response and reduced flex, resulting in better cornering and overall vehicle control.

Compatible with 1973–1977 A-Body and 1978–1988 G-Body models, these trailing arms are suitable for a variety of classic GM vehicles. They are intended for street, performance, and track applications where durability and handling are priorities. Designed as direct replacements, they bolt onto existing mounting points without modification. The kit includes the tubular trailing arms, ready for installation on vehicles that require a non-adjustable upgrade to their suspension system. These components are ideal for restoring or upgrading muscle cars and classic cruisers, providing a reliable, performance-oriented solution for improved suspension geometry.
