QA1 88-98 C1500 9in Rear Suspension Conversion System - Double Adj. - 200lb/in (STD Axle)

Rear Suspension System with OE Width QA1 9", Double Adj, 200lb/in. Springs

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 double-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. FACTORY WIDTH FOR EASY WHEEL FITMENT The included 9-inch housing features a 65" wheel mounting surface width that matches the factory width.

This makes wheel and tire selection more straightforward while maintaining the track width your OBS was originally designed around. The housing includes 31-spline axles, Big Ford New Style Torino housing ends with a 2.5" axle offset and dual 5x4.75" and 5x5" bolt patterns for compatibility with a wide range of brake and wheel combinations.

MODERN COIL-OVER PERFORMANCE Replace the factory rear suspension with a performance-focused coil-over system designed to improve suspension control and give your OBS truck a more responsive, modern driving experience.

DOUBLE-ADJUSTABLE COIL-OVERS QA1 double-adjustable shocks let you independently tune compression and rebound, giving you greater control over how your truck responds to different road conditions and driving styles. With 18 positions of adjustment for each, you can fine-tune ride quality, handling and traction for street driving or more performance-focused use.

The included 200 lb/in. springs provide a firmer spring rate for trucks built with a greater focus on handling and performance.

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.
