QA1 Front Classic Truck Conversion Kit - 1988-1998 Chevy/GMC C1500

Want your OBS truck to actually handle like a modern performance vehicle? The QA1 Front Classic Truck Conversion Kit overhauls your 1988-1998 Chevy or GMC C1500's front suspension with a true coil-over system, giving you height adjustability, tunable damping, and a level of control that stock or basic drop kits simply can't match. This bolts directly into your factory locations, no welding required, and includes every piece of hardware needed for a complete install.

QA1 offers this system in two performance levels. Level 2 delivers stock ride height or a 2" drop (2"-4" with drop spindles) using a single-adjustable Pro-Coil system that bolts back into the factory mounting locations. Level 3 steps it up with a 2"-4" drop (4"-6" with drop spindles), a fully double-adjustable coil-over, and an upgraded bolt-in upper control arm mount that improves geometry, reduces anti-dive under braking, and ties directly into the upper shock mount for a stiffer, more precise front end.

Every shock in this kit is dyno-tested and serialized, and QA1 offers your choice of Single Adjustability, Double Adjustability, or their premium MOD Shocks for on-the-car valving control, letting you dial in exactly the ride and handling balance you want. A wide range of spring rate options means this system can be tuned for anything from a smooth cruiser to a canyon-carving weekend build.

Kit Includes: Front coil-over conversion hardware, your choice of QA1 shock adjustability level, all mounting hardware. Made in the USA.

Fits: Chevrolet and GMC C1500 Pickup, Tahoe, Suburban, Yukon (OBS body only), 1988-1998, through 2000 for SUVs.

This is the suspension upgrade path for OBS owners who want to stop babying their truck through corners and potholes. Bolt-in installation, no bed removal, no welding, and a system engineered from the ground up for adjustability and performance.
