This belt and pulley kit from the OEM supplier to BMW is the best option for a direct replacement for the fragile and failure-prone stock plastic pulley. This kit is manufactured by Rein Automotive - one of the original suppliers to BMW for the pulley and the main drive belt.

This kit includes:
  • aluminum water pump pulley, replaces BMW part #11511730554
  • main drive belt, 6PKx1555 size, BMW part #11287636378
  • 4 x mounting bolts, M6x12 size, BMW part #07119904517

The stock part WILL eventually break from exposure to engine bay heat. We highly recommend replacing it as a preventative measure so it won't leave you stranded or stuck with expensive engine damage when it does break.

The main belt included in this kit is 1,555mm in length. We encourage you to check the belt size currently on the car to ensure compatibility. BMW notes the 1555 can be used in exchange with 1,560 and 1,562 length belts.

This is an OEM M50 belt and pulley kit manufactured by Rein - the original supplier to BMW for these parts, as well as many other engine parts. As the OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
