BMW Drive Belts & V-Belts

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.

This kit includes ECS Kevlar Reinforced Drive Belts, tensioners, and pulleys required to install the new tensioner. ECS Tuning's Red Kevlar Accessory Belts are both an aesthetic improvement and a performance alternative to a traditional belt. Kevlar-reinforced belts experience less elongation over time minimizing the amount of belt adjustment needed as well as offering a higher shock and impact resistance compared to OEM-style belts. Refreshing the rollers and/or tensioners simultaneously is a great way to ensure all vital components of your drive belt system are functioning optimally for years to come!

Rogue Engineering has developed a power pulley kit that reduces the drag on specific pulleys while allowing others to remain at their same efficiency. This allows for perfect operation in daily driven vehicles without a hiccup or stutter. However, when the demand for power is requested, the power pulley kit allows for the freed power to become apparent.  The term "power" pulley is a bit of a misnomer. Underdrive pulleys actually free up power by reducing the drag caused by the accessories.  These pulleys are based off a calculated percentage from factory dimensions, so that particular component speeds are safely reduced without affecting their true purpose.

Rogue Engineering Power Pullies are CNC machined from 6061-T6, heat treated aluminum and specially coated with a MIL-A-8625 Type III hard coat anodize finish. This kind of anodizing is not to be confused with a Type II cosmetic anodize finish (typical colors such as red, blue, silver, green, etc.). The hard coat anodize finish actually builds a small surface layer on top of the aluminum, preventing wear.

This part fits the following BMW engines:
S54

This part fits the following chassis:
E46, Z3, Z4

BMW has a seemingly endless number of fans of the N54/N55/S55 engines, three straight-six turbo engines that are each capable of 750+ horsepower, but that doesn't mean they were without their faults! BMW's N54 had a notoriously rocky start with reliability due to multiple issues such as fuel injectors failing, turbos failing, serpentine belt failure, crank hubs coming loose, and more... BMW made multiple attempts to fix the issues plaguing the N54, but they could only do so much and the fixes rolled out seemed temporary at best. Following the N54, BMW released their updated N55 and S55 engines, giving many people hope that these engines would address the previous issues. Unfortunately, this was only some-what the case. Crank hubs and crank bolts continued to loosen over time and serpentine belts continued to shred themselves and get pulled into the oil pan through the front main seal. For all three engines, this meant a single failure could effectively turn your engine into an oversized paperweight. Luckily for us, the BMW community is full of skilled enthusiasts who have gladly taken up the task to offer solutions! The first headache to be addressed was the Crank Hub and Bolt. Using a simple plate that fits perfectly over your crank hub's hex-head bolt and mounts up against the damper, the crank bolt is effectively locked in place, preventing it from being able to back out until the plate is fully removed. Next up was the serpentine belt failures. It's not known what exactly causes the serpentine belt to split, but once it does, the pieces hanging off of the belt wrap around and behind the damper. This leads to the belt breaking up into smaller pieces and eventually getting pushed between the crank hub and rear main seal into the oil pan. These small pieces of debris get caught in and block the oil pickup, preventing oil flow and leading to engine failure. To prevent this, multiple aftermarket companies came up with their own versions of Crank Seal Plates. This plate is installed behind the front damper, blocking the opening that allows the serpentine belt to pass between the crank hub and seal, keeping debris out of your oil pan! Also included in this kit are the components to service your front Oil Cooler/Filter Housing gaskets, refresh your drive belt system, and install the aftermarket upgrades.

The vibration damper in the E70 X5 35d is a common failure item and can fail at as low as 60 thousand miles leaving you stranded. This kit includes everything needed to replace your vibration damper and service your drive belt system! Vibration Dampers (also called Harmonic Dampers or Harmonic Balancers) absorb and remove unwanted vibrations due to torsional twisting of the crankshaft. During cylinder combustions, the crank quickly flexes ever so slightly, resulting in resonance vibrations. These vibrations could lead to damage of the crankshaft or crank bearings over time if not accounted for. The vibration damper helps to eliminate these vibrations, thereby extending the life of your engine's mechanical components and preventing damage. If your vibration damper has failed, you will likely notice excess engine vibrations or shaking that will gradually get worse, especially around certain RPMs where the vibration resonance is most pronounced. This basic kit includes the components necessary to replace your damper with an OEM damper from Corteco, including two belts and the Corteco Vibration Damper pulley. Also included in this kit is a brand-new line of specialty tools from Schwaben designed specifically for this replacement! You will get a Crankshaft Pulley Turner Tool, Stretch Belt Remover/Installer, T50 Alternator Wrench, and a 15/16" Pass-Through Socket, all included to make swapping out your old damper a quick and easy process! Standard tools you might need but are not included: 8mm Drill Bit (to use as flywheel locking pin) 32mm Fan Clutch Wrench - You may want a second 32mm to hold the coupler in place 24mm Box Wrench - For releasing tensioner Torque Wrench - To torque new crankshaft bolts Breaker Bar - to drive the crankshaft bolts further

Ensure the longevity of your BMW's engine with the accessory pulley.

Designed to prevent crankshaft failure caused by resonance vibrations, this accessory pulley is essential for maintaining your engine's integrity. With each cylinder firing, torque is transferred to the crankshaft, inducing vibrations. These vibrations, when synchronized with engine speeds, can lead to stress beyond the crankshaft's capacity, resulting in failure. The accessory pulley acts as a balancer, mitigating these vibrations and safeguarding your engine's longevity.

  • Prevents crankshaft failure
  • Balances vibrations for engine longevity
  • Safeguards against resonance-induced stress
  • Enhances engine performance and reliability
  • Specifically designed for BMW engines

The idea of power pulleys is simple. The less effort the engine puts into running accessories such as the water pump, power steering, pump alternator etc., the more of that power can be used elsewhere - your wheels! The way this is done by reducing the rotation of the pulleys by as much as 10-20%! The end result is more horsepower at your disposal. Turner has done extensive testing (on and off the track), to ensure that the accessory systems still function as intended and without failure. These pulleys offer an excellent compromise of power gains, reliability, and performance.

These pulleys are precision made from domestic USA 6061-T6 Billet Aluminum. They have undergone thousands of hours in testing, race use, and street miles accumulated to show these pulleys work great and give you the edge.

This 3 Pulley Race Set is a very popular choice: just like the 2 pulley set, a precision power steering pulley and water pump pulley are included, but VAC includes an additional underdriven alternator pulley for maximum power output on the track.

Free additional power to your M3’s rear wheels without sacrificing or compromising your BMW’s reliability. Machined from 6061-T6 aerospace aluminum, Macht Schnell Performance Underdrive Pulleys are strong as well as lightweight to limit parasitic drag from the accessories within a moderate level for maximum performance on or off the track. After machining and engraving, pulleys are then T3 hard anodized for additional strength, anti-corrosion & wear resistance. Our DualDrive design replaces the Crank Accessory & Power Steering Pulleys, resulting in an additional 9-14 HP and 7-9ft. lbs TQ gain for the M3. Gains are due to a reduction in power required to turn accessories; an increase in accessories lifespan due to lower speed will also result. All factory harmonics/balancing are undisturbed. Macht Schnell Performance Underdrive Pulleys have no negative effect on accessory operation and comes fully equipped with new belts. Already have this kit and need new belts? See T#14491 and T#14489 Performance Underdrive Pulleys Features: DualDrive design allows maximum performance, with minor effect on accessory speed Proper cooling temperatures are retained at proper levels on or off the track Maintains proper alternator speed, allowing sustained levels to sensitive control modules Machined from 6061-T6 aerospace aluminum T3 Hard-Anodized for maximum strength and corrosion/wear resistance No affects to crankshaft dampening or harmonics Simple bolt-on installation

The Power Pulley reduces rotational mass and safely under drives your belt driven auxiliaries for reduced parasitic power loss.

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
