QA1's Level 3 front coil-over conversion system for 1988-1998 OBS Chevrolet or GMC C1500 trucks integrates control arms with coil-over shocks to provide up to 6" of drop with the use of popular drop spindles or up to 4" of drop with stock spindles.  This kit is designed for both truck enthusiasts and everyday drivers who demand superior handling, ride quality, and performance from their vehicles.

DIAL IN THE PERFECT STANCE

Achieve a perfect stance with up to a 6-inch drop when used with drop spindles in the front. With QA1's user-friendly adjustability, you can tailor your truck's ride height to your exact preference, ensuring the perfect look and optimal performance.

MODERN GEOMETRY

Through QA1’s improved suspension geometry, your OBS truck will feel like a modern vehicle with enhanced handling and ride characteristics. Experience a smoother, more controlled ride with suspension technology that brings your classic truck’s performance into the 21st century. This advanced geometry enhances stability, steering response, and overall drivability, making your truck handle like a dream.
