Shop OBS Parts

Suspension is our deepest category, split by how you want your truck to sit: 1500 lowering kits and C2500/C3500 lowering kits & static suspension for a slammed stance, or air ride and components — shop 1500 and 2500/3500 specific kits, compressors, control systems, overload kits, or individual parts & bags for a true bagged dually or 1500. Lifting instead? OBS lift kits covers 1500-series trucks, while K2500/K3500 lift kits is built for 3/4-ton and 1-ton 4x4s.

Wheels are broken out by bolt pattern so fitment is never a guess: 5-lug, 6-lug, and 8-lug cover single-rear-wheel trucks, while 8-lug dually and 10 lug dually wheels & adapters (including semi wheel adapters) are built specifically for dually trucks. Need lug nuts to finish the install? We carry those too.

Braking hardware is organized by axle and truck series: C1500, K1500, C2500/C3500, and K2500/K3500 brake kits, plus disc brake conversion kits for trucks still running drums. Steering follows the same pattern: 1500, 2500, and 3500 steering parts.

For the rest of the truck: exterior parts & accessories, interior parts, front and rear bumpers, and lights & lighting plus offroad lighting. Planning a GMT400 engine swap? Dedicated LS, LT, and Duramax swap parts collections carry the brackets, mounts, and accessories those conversions need.
