SpeedFactory Racing AWD B-Series Billet Bellhousing

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.

Superior incorporated design elements include:

• Modified countershaft bearing retention plate location clears larger diameter aftermarket countershaft teeth while retaining OEM plate and locking tab with no need for any grinding or modification. (2022+ product update)
  
• Clears oversized (vs stock) PPG crown wheel & transfer drive gear
• 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 SpeedFactory Racing AWD B-Series Billet Transfer Case 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.
