Product Details

The QA1 OE Width 9" Rear Suspension System is built for the 1988-1998 Chevrolet C1500 RWD.

Upgrade the rear suspension of your 1988-1998 Chevrolet C1500 OBS truck with a complete QA1 Rear Suspension System, paired with a standard-width 9-inch housing and 31-spline axles. This system combines adjustable coil-over performance with straightforward wheel and tire fitment. The standard-width housing maintains the factory 65" 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 65" wheel mounting surface width maintains the factory rear track width.
  • Modernize your OBS 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, standard-width 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.
