QA1 Handling Kit HK03-OBS1RS

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 standard-width 9-inch housing with 31-spline axles into one matched package. Designed for drivers who want more from their OBS, the Level 3 system combines firmer spring rates with greater shock adjustability for improved handling and suspension control. The standard-width housing maintains the factory rear track width for straightforward wheel and tire fitment. COMPLETE FRONT-TO-REAR PERFORMANCE Upgrade the entire truck with components designed to work together. Up front, tubular control arms and coil-overs improve suspension geometry, steering response and control. Out back, QA1's torque arm suspension improves traction and suspension control while allowing an adjustable 4-7" drop. The front provides up to 2" of drop with stock spindles or up to 4" when used with drop spindles, giving you plenty of flexibility to dial in your OBS truck's stance. 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 rear 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.
