Product Details

The QA1 OE Width 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 standard-width 9-inch housing and 31-spline axles. This system combines 4-way adjustable MOD Series coil-over performance with straightforward wheel and tire fitment. The standard-width housing maintains the factory 63-5/8" wheel mounting surface width, making it easy to build around common wheel and tire combinations while maintaining the factory rear track width.

Features

  • Easy wheel and tire fitment: Standard 63-5/8" wheel mounting surface width maintains the factory rear track width.
  • Take control with 4-way adjustability: Independently tune high-speed and low-speed compression and rebound to dial in ride quality, handling and traction.
  • Tune for the street or track: Separate damping adjustments let you optimize suspension behavior for different driving conditions and performance goals.
  • Expand your tuning range: QuickTune™ valve packs allow internal valving changes without removing the shocks from the truck.
  • 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, MOD Series shocks, standard-width 9-inch housing and 31-spline axles are packaged together to simplify your build.
