OBS Engine Parts and Swap Supplies
OBS engine parts and swap supplies for 1988-1999 Chevy and GMC GMT400 trucks, including the C/K1500, C/K2500, C/K3500, Suburban, Tahoe, Yukon and Blazer. Whether you are refreshing the original engine or dropping a modern powerplant into your OBS, start with the category that matches your build.
Planning an engine swap? Browse OBS LS swap parts, LT engine swap parts and Duramax swap parts for mounts, adapters and the supporting hardware these conversions need. Pair them with an OBS fuel system swap and LS swap wiring so the engine bay comes together cleanly.
For maintenance and performance upgrades, see oil coolers and fitting kits, cold air intakes, belts and cooling parts and ignition parts.
Swapping an engine usually affects more than the engine bay. Plan the rest of the build with OBS brake kits, steering and suspension parts and OBS wheels and tires, or return to all OBS parts categories.
Fitment on swap parts depends on your year, model, drivetrain and the engine you are installing. Call or text (970) 634-3577 or email OBSRevivalParts@gmail.com with your truck and engine details and we will help you pick compatible parts.
