SpeedFactory Racing FWD B-Series Billet Bellhousing

Unmatched quality, unrivaled performance. The ultimate choice for your FWD B-Series transmission. In a racing environment where thousandths of a second decide whether you win or lose, you can’t afford to not use the best!

The SpeedFactory Racing FWD B-Series Billet Bellhousing was designed to be the ultimate billet bellhousing - precise, accurate, & pain-free to build without being unnecessarily bulky and heavy, weighing in at an impressive 6-7lbs lighter than other existing offerings.

After a year of painstaking development and real-world testing & refinement we are extremely proud to finally release the SpeedFactory Racing FWD B-Series Billet Bellhousing!

Precision CNC Machined from Solid 6061-T6 Aluminum Billet, our design is only 7.6lbs heavier than the weak cast OEM housing while providing extreme strength and durability needed for the highest-powered street and motorsport applications.

Incorporated design elements include:

• Built-in housing separation feature (makes splitting the cases for servicing a breeze using an existing case bolt)
• 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)
• Clears both GSR/ITR and B16/LS fitment LSD’s
• Built-in axle seal stop (for easy & precise depth control during installation)
• Retains OEM oil control features missing in other existing offerings
• Utilizes x3 shoulder bolts for precise SCHA location

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 FWD B-Series billet bellhousings are designed to work with both OEM style single plate or multiplate twin & triple disc 7.25” clutches and both stock clutch fork & release bearing or hydraulic release bearing. Compatible with all currently known aftermarket gearsets, transfer drive gears, and differentials.
