Stock lower trailing arms are flimsy and weak, leading to poor handling and excessive wheel hop. Most of the aftermarket offers conventional fabricated steel trailing arms with polyurethane bushings -- a design that is very stiff, but does not allow for the axle to move freely throughout the range of motion. This can cause a bind in the rear suspension, leading to snap oversteer and unpredictable handling. PST's Catapult® Billet Aluminum Trailing Arms solve this problem with an innovative solution that delivers smooth, consistent, predictable handling for your GM musclecar.

Starting with a solid block of 6061-T6 aerospace grade aluminum, we machine a sleek superstructure that yields an incredible strength-to-weight ratio. Each end is fitted with an Alu-Max® Pivot Joint -- a low-friction spherical joint that allows for 30 degrees of articulation. The Alu-Max® Pivot Joint is comprised of two Delrin® races and a lightweight hard anodized, 7075-T6 aerospace grade aluminum spherical ball. The sway bar mounting holes allow for the installation of any stock or aftermarket sway bar that mounts in the factory location. A military spec black anodizing is applied to the entire superstructure and the arm is finished off with a white PST and Catapult® logo.
