QA1 Handling Kit HK03-OBS1RN

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. The narrowed rear housing also opens up more options for wider wheels and tires. 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 rear 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. MORE WHEEL OPTIONS, BETTER FITMENT The included 9-inch housing features a 61" wheel mounting surface width, 4" narrower overall than the factory 65" width. The additional 2" per side works with mini-tubs to provide greater flexibility in wheel width, backspacing and offset, making it easier to fit wider wheels and tires under your OBS. 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.
