Trailing Arm Upper Rear GM B-Body 65-67

The QA1 Trailing Arm Upper Rear for GM B-Body 1965–67 is an essential suspension component designed for automotive enthusiasts and restorers looking to enhance rear-end geometry and handling on classic Chevrolet, Pontiac, and Oldsmobile vehicles. This upper trailing arm replaces the original rubber-bushed factory design, which can degrade over time and negatively impact on-road stability and drag-strip performance.

Featuring a rigid rod design, this upper trailing arm minimizes deflection under load, ensuring precise axle alignment during acceleration, braking, and cornering. It is compatible with modern spherical or poly bushings, which are sold separately, allowing users to customize compliance and damping characteristics based on their suspension setup, whether using coil-overs, air suspension, or factory-style leaf springs.

This trailing arm is particularly beneficial for those upgrading 1965–1967 Chevrolet Chevelle, Malibu, or El Camino platforms, as well as Pontiac Tempest and Oldsmobile Cutlass models. Its 20.55-inch length and bolt-in installation ensure a seamless fit with the original B-Body frame, making it an ideal choice for anyone looking to enhance their classic car's performance.
