Looking to upgrade your plastic pulleys for lightweight aluminum? The stock pulleys on these BMW engines become brittle and break with use and heat.  Our pulleys are machined out of one piece of lightweight aluminum and anodized black.  This is a great upgrade for any BMW. This kit includes an aluminum water pump pulley, power steering pulley, and serpentine belt.

Fitment: E36, E34, E39, E46, E53 with M52, M52Tu, or M54

Please choose the proper kit to receive the correct size belt.  If you have any questions, please email us at info@racegerman.com
