Collection: Transmission Bell Housings

Connect your engine to your gearbox safely and securely with replacement and high-performance transmission bell housings. Serving as the primary structural interface between the engine block and transmission case, the bellhousing surrounds the flywheel, flexplate, clutch assembly, or torque converter while maintaining precise input shaft centerline geometry and starter motor positioning.

Whether you're replacing a cracked factory aluminum bellhousing on a daily driver, setting up an engine swap adapter plate for a custom build, or installing an SFI-rated steel scattershield for drag racing safety, having a rigid, properly aligned housing is critical. Explore lightweight cast aluminum replacement bellhousings, heavy-duty explosion-proof steel scattershields engineered to contain flywheel or clutch fragmentation under violent high-RPM failure, manual swap bellhousings, inspection covers, alignment dowel pins, and high-strength mounting bolt kits across automatic and manual transmission setups for street, strip, diesel, and off-road builds.
