Differential Flange Adapters

Upgrade your driveline with this precision-engineered billet aluminum adapter, designed to seamlessly connect your BMW differential to a high-performance single piece driveshaft. Perfect for eliminating the problematic guibo and two-piece driveshafts and replacing it with a stronger, lighter single-piece driveshaft, especially when paired with our BMW transmission adapters.

Precision-machined to strict tolerances, this adapter ensures a perfect fit and enhances overall driveline performance. Design features centering rings and nubs to achieve perfect alignment. Built to last, the 1350 U-joint offers superior durability compared to factory parts. 

Includes high quality hardware. Has been used on vehicles with over 1300hp without issue.
