The SpeedFactory Racing AWD B-Series Billet Bellhousing is your ultimate choice - precise, accurate, & pain-free to build unlike others. Proven in our 6 second 2000hp B-Series OUTLAWD drag car.
Unmatched quality & unrivaled performance, a truly functional work of art as noted by all the top teams and shops that have made this housing the foundation of choice for their AWD B-Series racing transmissions.
Precision CNC Machined from Solid 6061-T6 Aluminum Billet, our design is only 9lbs heavier than the weak cast OEM housing while providing extreme strength and durability needed for the highest-powered street and motorsport applications.

- Built-in axle seal stop (for easy & precise depth control during installation)
- Retains OEM oil control features missing or done incorrectly in other offerings
Pair with our for the ultimate proven B-Series AWD combo!
NOTE: Requires assembly and shimming to OEM specifications. It is highly recommended that you have the installation performed by a reputable transmission rebuilding specialist. The SFR housings were designed to work with multiplate twin or triple disc 7.25” clutches and a hydraulic release bearing. Use of a stock clutch fork & release bearing may require minor clearancing on older housings manufactured in early 2021. Housings manufactured in 2022 clear oem clutch forks. Compatible with all currently known aftermarket gearsets, transfer drive gears, and differentials.
