SpeedFactory Racing AWD B-Series Billet Transfer Case

After a full year of development, testing, and refining the SpeedFactory AWD B-Series Billet Transfer Case is now available to the public!

Machined from a Solid 7075-T6 Aluminum Billet, our design is massively stronger than the weak cast OEM case and ~85% stronger than the typically used 6061-T6.

A unique design feature is a large diameter 4-bolt inspection cover to allow quick and easy on-car inspection as well as facilitate ease of use during assembly.

Each housing is also supplied with a solid titanium dowel pin (say goodbye to bent/crushed OEM dowels due to transfer case rotation) and x4 identical length flange bolts for mounting that precisely locate the body along with the dowel pin to stop rotation under hard drag launches and eliminate the need for a trans to block brace.

Each housing goes through a rigorous 15-point QC checklist to ensure you don’t run into any issues during assembly with bearing tolerances, tapped holes, or part fitment/interference. O-rings, output shaft seal, and bolts are included.

Key Benefits:

• High strength 7075-T6 billet aluminum body
• The bearing cap is also 7075-T6 with ultra thick under-bolt mounting flange and is the strongest available. This keeps the hypoid gears in position better than others - hypoid separation under power is a well-known B-Series transfer case design issue that contributes to breakage
• Large inspection cover makes assembly and inspection a breeze
• Includes solid titanium dowel pin which eliminates the usual OEM dowel failures
• No more dealing with multiple different length mounting bolts like OEM - supplied with x4 identical mounting bolts that precisely locate into machined pockets on the transfer case body to stop case rotation under hard launches.
• These unique design elements are the result of cumulative real world experience via our engineering, transmission building, and race teams to deliver the ultimate combination of ease of use and strength - you are getting a product that is track tested & proven to deliver ease of use and strength under extreme conditions in the World's Fastest B-Series AWD drag cars.

Pair with our AWD B-Series Billet Bellhousing for the ultimate proven B-Series AWD combo!
