Performance Suspension Technology - Trailing Arm Kits
PST's Catapult® Arms are designed to put maximum power to the ground delivering ultimate performance off the line. Stock trailing arms are flimsy and weak, leading to poor handling and excessive wheel hop. Competitor's steel lower trailing arms are heavy and don't allow the axle to move freely throughout the range of motion. PST's Catapult® Billet Aluminum Lower Trailing Arms solve this problem with the innovative solution that delivers smooth, consistent, predictable handling for your GM A-body: the Alu-Max Pivot Joint, a lower friction spherical joint that allows for 30 degrees of articulation for bind-free movement.
