Ford Performance 4.6L/5.0L/5.4L Modular Bellhousing M-6392-M46

If you're swapping a Tremec transmission into your modular Ford engine platform, this bellhousing is the critical link between your engine and gearbox. Ford Performance engineered this casting to handle high-rpm shifts and sustained power delivery without the weight penalty of iron—essential if you're building a track car or street performance machine. Getting the bellhousing right eliminates guesswork during installation and ensures proper clutch geometry and starter clearance.

The M-6392-M46 is cast aluminum, keeping rotating mass low while maintaining the rigidity needed for aggressive driving. It's compatible with 4.6L, 5.0L, and 5.4L modular engines, including the newer 5.0L Ti-VCT variant, and mates directly to Tremec 3550, TKO, or TKX transmissions. The housing includes provisions for the Ford Performance starter index plate and clutch release lever, streamlining your build. Note that some applications may require minor modifications for transmission clearance and mounting—consult your engine swap documentation or a fabricator if you're working with a non-standard installation.
