SPEEDFACTORY RACING AWD B-SERIES BILLET BELLHOUSING

The SpeedFactory Racing AWD B-Series Billet Bellhousing was originally designed in response to the need for a top-level billet bellhousing that is precise, accurate, and pain-free to build without being unnecessarily bulky and heavy.  

After a year and a half of painstaking development and real-world testing & refinement to ensure that you have a painless transmission building experience, and we are extremely proud to finally release the SpeedFactory Racing AWD B-Series Billet Bellhousing!

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. 

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 are designed to work with multiplate twin or triple disc 7.25” clutches and stock clutch fork & release bearing or a hydraulic release bearing. Compatible with all currently known aftermarket gearsets, transfer drive gears, and differentials.
