Rear Suspension GM C10 73-87 Single Adj. Med

The Rear Suspension GM C10 73-87 Single Adj. Med by QA1 is a complete suspension overhaul solution purpose-built for Chevrolet C10 trucks spanning 1973 to 1987 model years. This kit addresses the critical need for modern ride control, handling stability, and load-carrying capability in classic trucks that originally came equipped with outdated, soft suspension geometry. Whether you're restoring a vintage workhorse or upgrading a daily driver, this single-adjustable rear suspension system delivers the performance demanded by truck enthusiasts and professional builders who refuse to compromise on chassis dynamics.

Built from welded steel with a durable black powder-coat finish, this comprehensive kit includes all essential components: coil springs rated at 200 lb/in spring rate, matched shock absorbers, a crossmember, Panhard bar for lateral wheel control, torque arms to manage axle wrap, trailing arms for precise geometry, and a complete setup designed around the GM 10-bolt rear differential. The 200 lb/in spring rate strikes the balance between load support and ride compliance—stiff enough to handle payload and cornering forces while remaining compliant on uneven surfaces. The single-adjustable shock configuration provides tuning flexibility without excessive complexity, allowing fine-tuning of damping characteristics to match driving conditions and personal preference.

This suspension system is engineered for full-size GM trucks with the 10-bolt rear end configuration and benefits both street-driven classics and weekend warriors seeking improved handling. Professional restoration shops, vintage truck collectors, and hot rod builders rely on QA1 kits to deliver predictable, responsive chassis performance. Installation requires basic mechanical competency and proper alignment procedures post-setup. Compatibility is confirmed for all 1973–1987 Chevrolet C10 trucks equipped with factory 10-bolt differentials. The complete kit approach eliminates guesswork and component mismatch, ensuring all suspension geometry works in concert for maximum effectiveness and safety.
