A new breed of trailing arms from the industry leader in musclecar technology -- PST. Catapult® Billet Aluminum Lower Trailing Arms with Alu-Max® Pivot Joints are the finest trailing arms available for your GM A-body.

For pricing and ordering info, see Catapult Billet Aluminum Lower Trailing Arms

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.

Get the ultimate trailing arm for the street, strip, or track -- order today! Be sure to pick up a set of matching Catapult® Adjustable Upper Trailing Arms and Frame Reinforcement Braces to complete the package. Our upper trailing arms feature a bulletproof steel construction and a low-friction Alu-Max® Pivot Joint, and can even be adjusted on the vehicle to change the pinion angle - crucial to lowering your 60 foot times, increasing traction, and reducing wheel hop! The Frame Reinforcement Braces triangulate the upper and lower trailing arm mounts for added strength and driving performance. These braces are pre-bent to contour to the floor of the vehicle, allowing for installation without modification.
