Product Details

The QA1 Level 3 Handling Kit with Narrowed 9" Housing is built for the 1988-1998 Chevrolet C1500 RWD.

Transform your 1988-1998 Chevrolet or GMC C1500 OBS truck with a complete QA1 Level 3 Full Vehicle Handling Kit. This front-to-rear system combines tubular front control arms, double-adjustable coil-overs, QA1's rear suspension system and a narrowed 9-inch housing with 31-spline axles into one matched package. Built for drivers who want more performance from their OBS, the Level 3 system combines firmer spring rates with greater shock adjustability for more aggressive handling and suspension control.

Features

  • Upgrade the entire truck: Front and rear suspension components are engineered to work together as one complete performance system.

  • Fine-tune ride and handling: Double-adjustable shocks provide independent compression and rebound adjustment for greater control over suspension behavior.
  • Step up handling performance: Firmer Level 3 spring rates provide a more performance-focused suspension setup for aggressive driving.
