Please PM me for pricing/inquiries. :cheers:



The Power Pulley is a smaller diameter pulley engineered to replace the OE crankshaft pulley. Since it is smaller in diameter, it drives the auxiliary accessories at a reduced rpm and reclaims some of the parasitic loss that is usually absorbed by driving these components.

The RDSport Power Pulley is made out of aerospace-quality 6061-T6 aluminum and is then anodized in the traditional RDSport blue. It is supplied with the 2 shorter Micro-V belts that compensate for the smaller diameter of the pulley.

On the 10 cylinder M5 we have seen a consistent gain of around 12-16HP, which make the power pulley option a very effective performance upgrade.


Installation takes approx
1.5 - 2.5 hours.
