68-72 GM A-Body Heavy-Duty Trailing Arm Kit

Upgrade the rear suspension of your 1968-72 GM A-body with Speedway Motors' HD Trail Arm Set. This complete package combines heavy-duty rear lower trailing arms, adjustable upper control arms, and sway bar mounting arms to improve chassis stability, suspension tuning capability, and overall vehicle handling. Built from durable steel components and equipped with performance-oriented bushings and adjustable geometry, this kit is ideal for street performance, pro touring, autocross, and drag racing applications.
