This is the proper way to 6MT swap your E36 and E36 M3 that uses a 4-bolt driveshaft. The widely known current method is to use an automatic M3 driveshaft, but the center slip joint is hanging on by a super minimal amount of contact. This is a failure waiting to happen. Not to mention most all used driveshafts have failed u-joints or other issues.
Made in the US with a lead time of 1week! These are built to order and custom spec'd by MSP to be plug and play with your Getrag 420G 6MT swap. Built using OE-grade flanges, uprated (replaceable) u-joints, and properly balanced as one part.
Driveshaft ships from the California based manufacturer fully assembled with center support bearing. Add your own Giubo (flex disc) and install!
