BMW Drive Belts & V-Belts for BMW 6 Series E63 (2004-2010)

Clear BMW chassis

Please ensure your correct model is selected

Your BMW's drive belts are wear items, and will degrade and crack over time. Don't wait until you have a belt failure... don't get stranded! Replacing your BMW's belts, such as the alternator belt, power steering belt, air conditioning AC belt, or serpentine belt is a low cost insurance policy to preventing a break down -- or worse, engine damage. We recommend checking your belts every 10,000 miles. If your belts have excessive cracks, dry rot, missing teeth and/or grooves, are cause noise, it's time for new ones.

While also inspecting your serpentine belts, also check for wear or resistance in the pulleys. The tensioner pulley and deflection pulley are the primary sources for belt squealing. The rubber-isolated pulleys can also break apart, leading to total belt failure. We sell the tensioner and deflection pulleys for the M50 engine family used in the E34, E36, E39, E46, X5, Z3, and Z4.

Get MORE HORSEPOWER and TORQUE on your 2006 and newer M5 sedan or M6 coupe/convertible by replacing the stock crank pulley with this specially designed performance version. The Power Pulley reduces rotational mass and safely under drives your belt driven auxiliaries for reduced parasitic power loss. The end result: More power to your M5 or M6's rear wheels! Designed to give the best performance benefit with no sacrifices or compromises to your BMW's reliability. These have been tested on hundreds of cars before public release and there are simply NO DOWNSIDES to this upgrade.

Limited time introductory offer: FREE GROUND shipping on all orders shipped within the 48 contiguous states shipping on this V10 pulley kit.


CNC machined using aircraft grade 6061 aluminum billet, and anodized with a stealthy black coating. Others may advertise "their" crank pulley boasting higher numbers (using a smaller pulley profile), but we have concluded that for street and track driven M5 and M6, this is the best size and design to ensure proper engine temp and auxiliary functionality. As the S85 V10 engine doesn't use a traditional harmonic balancer, all factory harmonics and dampening are fully and properly retained. We've found this pulley alone adds 18 to 22 HP and 17 to 21 Ft/lbs Torque on a stock M5 or M6 with no other mods(!!).

The E60 M5 / E63 M6 Power Pulley Kit includes:
(1) Underdrive Crank Pulley
(1) Correctly Sized Drive Belt
(6) Allen Head Bolts
(1) Installation instructions

This underdrive pulley fits the following BMWs:
2006-2010 E60 M5 sedan
2006-2010 E63/E64 M6 coupe & convertible

Hydraulic Belt Tensioner for E9x M3 with S65 engine and E60 M5, E63 M6 with S85 engine. This oil-filled tensioner keeps the main drive belt in the proper tension. Over time, the seals wear, allowing fluid to leak out and the tensioner then becomes frozen or inoperable. Replacement is the best corrective action to take. This can be done during any belt or pulley service or anytime the fan is off the engine.

If you vibration damper is failing, it will usually present itself in the form of a squealing noise that sounds like a slipping belt. This is an indication that the rubber ring inside of the vibration damper has dried out and cracked, causing the pulley to slip.
