We've upgraded all our BMW transmission swap kits for the NA and NB Miata with a new 3.5" aluminum driveshaft.
This driveshaft features larger diameter splines, machined to extremely tight tolerances for exceptionally smooth operation at high speeds. It eliminates any potential slop found in older steel shafts with smaller splines, ensuring a more precise and refined driving experience.
Available in four configurations to match your setup:
- BMW 5-speed to Getrag differential
- BMW 5-speed to Miata differential
- BMW 6-speed to Getrag differential
- BMW 6-speed to Miata differential
This driveshaft requires our driveshaft adapter for the transmission flange, and configurations using a Getrag differential also require an additional adapter.
Driveshafts are built to order, so please allow approximately 14 days for delivery.
