Upgrade your BMW's performance with Turner Power Pulleys, designed to enhance engine efficiency and increase available horsepower. These pulleys reduce the rotation of essential accessories by up to 10-20%, redirecting engine power to the wheels. Turner ensures these pulleys maintain proper functionality through rigorous on and off-track testing.
Crafted from durable T-6061 aluminum and finished in black hard anodizing, Turner Power Pulleys offer longevity, heat resistance, and chemical durability. They retain the stock-like appearance while providing increased strength and reduced weight, eliminating concerns about plastic failure.

This pulley is mounted along with the hydraulic belt tensioner but can be replaced on its own. It is used for the main drive belt on the M50-M54 family engines (M50, M50TU, M52, S52, M52TU, M54, M56, and S54 engines). This is the same belt that covers the water pump/alternator/power steering systems. Replacement is a very easy procedure (requires fan removal) and will have your engine purring in no time. Belt replacement is strongly recommended at the same time. If you have a mechanical belt tensioner, the pulley can only be replaced with a new tensioner.
This high-quality replacement from Bremmen Parts is designed for exact fitment on your BMW. Whether you're looking to complete much-needed preventative maintenance, or replacing a failed roller, choose this component from Bremmen Parts for a lasting repair.
