80mm BMW Differential Flange Adapter

This differential flange is used to adapt 80mm bolt circle differential flanges commonly found in E39 BMWs fitted with automatic transmissions and the 525i with the manual transmission to 1350 spicer yokes.

Perfect for those who want to keep their existing differential and axles when doing power upgrades or a transmission swap.

Precision machined out of lightweight 6061 aluminum with form tapped threads for extra strength.
