Swapping to a M3 differential in your 135i or 335i is an amazing upgrade because of the stronger axles and the limited-slip differential. The most annoying part of the swap is finding a shop to cut and weld two OEM shafts together to create one you can use. Often this is a ripoff and ends up vibrating. 
 
Skip the hassle of welding two OEM shafts together, and instead go straight to the much stronger and lighter 3.5" aluminum single piece driveshaft that we offer. This shaft features billet adapters, a quality DANA slipshaft, and super strong 1350 U-Joints that can take as much power as you can throw at them. Installation is as simple as just bolting it into place. 
 
If you are running an engine swap, let us know and we can make a shaft to suit as well.
