Crankshaft underdrive pulley kit for V10 M5 / M6 (fits E60, E61, E63, E64)

Instant power gain for your M5 or M6! By reducing the crankshaft pulley size, you lower the parasitic losses from driving the alternator, AC compressor, etc. by slightly lowering the rpm they are driven at. This leads to instant power gains of 12 to 20 hp, depending on your engine and environmental conditions.

  • Instant power gains
  • Easy, bolt-on installation
  • Everything needed is included in the kit, incl. quality stainless steel hardware


  • CNC machined out of 6061 billet aluminium
  • Anodized in black, CNC engraved
  • Smaller size, compared to the OEM pulley, providing 12-20 hp gains

What's included:

  • Aluminium underdrive pulley
  • 6x Stainless steel bolts and washers
  • 2x belts with the correct size for the smaller pulley
