Product Description

The QA1 5201 Adjustable Lower Rear Trailing Arms are a premium replacement and upgrade solution for 1971-1996 GM B-Body platforms. By replacing the factory-pressed steel arms with these heavy-wall tubular versions complete with greasable polyurethane bushings, you achieve superior rigidity, improved alignment stability, and compatibility with high-performance setups (large wheels/tires, coil-overs, raised powertrain loads).

Built to exact mounting dimensions for the B-Body chassis, these trailing arms install using the original differential housing and axle-location points, making the upgrade straightforward. The adjustable length ensures you can dial in pinion angle, wheel placement and tire clearance, which is especially beneficial for suspension modifications and performance builds. Whether restoring or upgrading, the QA1 5201 kit gives rear-suspension strength and precise handling control.

Note: Use of this kit may require the installation of an axle-mounted sway bar instead of the factory trailing arm-mounted bar (factory bar may not be compatible with the tubular arms). Always inspect clearance, alignment and torque specifications during installation. Recommended for both restoration and high-performance B-Body builds.
