Details & Inspection Notes
QA1's HK02-OBS1 is a front and rear coilover conversion for the 1988-98 Chevy/GMC C1500, pairing single adjustable coilovers at all four corners with front and rear coil springs. On the back, a torque arm and panhard bar take the place of the factory leaf springs; up front, tubular upper and lower control arms and a black powdercoated sway bar handle the geometry.
What to check before buying
Because this is a complete front-and-rear package rather than one end alone, check whether you need both halves before buying it versus one of QA1's rear-only kits for this truck. Nothing in this listing calls for welding or bed removal to get it installed.
What comes with it
The control arms are steel, powdercoated black, and the bushings throughout the kit are polyurethane. Mounting hardware for the full installation is included, and QA1 sells it as one complete kit.
Does it cover both the front and rear suspension? Yes, this kit includes coilovers and control components for both ends of the truck.
Do I need to remove the bed to install it? No, QA1 lists this as a bolt-on install with no bed removal.
