Gen2 Transmission Adapters

Upgrade your BMW’s driveline with this precision-machined billet aluminum adapter, designed to seamlessly connect your transmission to a high-performance, single-piece driveshaft 1350 yoke. Say goodbye to the problematic guibo and 2-piece driveshafts and enhance your vehicle’s durability and performance with a stronger and lighter driveline. Crafted from high-quality 6061 aluminum and engineered to exacting tolerances, this adapter ensures a vibration-free experience and optimized driveline balance.

Compatible with manual, automatic, and DCT models, it’s the perfect solution for BMW owners looking to reduce rotational mass and improve overall performance. Weighing only 12.6 ounces, it’s dynamically balanced with advanced software for a smoother, more efficient operation.
