Our OBS parts for suspension lineup covers lift kits for off-road builds and lowering kits — drop spindles, lowering coils, and flip kits — for a slammed static stance, plus air ride components (bags, management systems, compressors, tanks) for bagged dually and 1500 builds. OBS parts for wheels are broken out by bolt pattern — 5-lug, 6-lug, 8-lug, 8-lug dually, and 10-lug dually wheels & adapters — so fitment is never a guess.

Beyond suspension and wheels, shop OBS parts for billet, grills (89-93 & 94-98), bumpers, steering components, and axle-specific brake kits round out the catalog, along with OBS parts for engine swaps — dedicated LS, LT, and Duramax kits — plus off-road & recovery gear.

New parts land in our New Arrivals collection regularly. Every part is chosen for correct OBS/GMT400 fitment first — if you're not sure what fits your truck, reach out and we'll point you to the right part.
