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.
