Product Details

The QA1 Narrowed 9" Rear Suspension System is built for the 1963-1972 Chevrolet C10 RWD.

Upgrade the rear suspension of your 1963-1972 Chevrolet C10 with a complete QA1 Rear Suspension System, paired with a narrowed 9-inch housing and 31-spline axles. This system combines adjustable coil-over performance with more flexibility for modern wheel and tire fitment. The narrowed housing is designed to complement mini-tubbed C10 trucks while opening up more options for wheel fitment.

Features

  • Fit wider wheels and tires: Narrowed 9-inch housing provides an additional 3-1/4" per side for mini-tub applications.
  • Modernize your C10 suspension: Coil-over suspension provides greater suspension control and a more performance-focused driving experience.
  • Tune the ride to your preference: Single-adjustable coil-overs provide 18 positions of adjustment for comfortable cruising or more responsive handling.
  • Build around your preferred wheels and brakes: Dual 5x4.75" and 5x5" bolt patterns and Big Ford New Style Torino housing ends provide compatibility with a wide range of combinations.
  • Start with a complete, matched system: Suspension components, coil-overs, narrowed 9-inch housing and 31-spline axles are packaged together to simplify your build.
  • Performance you can count on: QA1 shocks are 100% dyno tested and serialized.
