BMW Drive Belts & V-Belts for BMW X Series E83 (2004-2010)

Clear BMW chassis

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.

If you are breaking crankshafts and oil pumps, the cause may be a mystery to you as it has been to many of our customers. We know that controlling the harmonic resonance of the BMW 6 is highly important as RPMs rise, but the ideal configuration of the inline-6 motor makes even experienced engine builders overlook some fundamental principals of engine harmonics that can be destructive. ATI Performance Products has partnered with VAC Motorsports to develop new dampers for BMW 2.5L, 2.8L, 3.0L and 3.2L straight-6 engines found in the E36 and E46 M3, E9X and E6X, as well as newer Z3s and Z4s. These dampers eliminate crankshaft harmonic vibration, which allows the engine to produce more horsepower and torque, while also reducing internal engine wear at the same time. Broken oil pumps and timing chains will be a thing of the past! When used with a VAC accessory pulley, these dampers are a direct replacement over the OEM balancer. They have a 7” outer diameter and include OEM style timing alignment tabs. BMW enthusiasts should know that all ATI Super Dampers exceed SFI 18.1 Safety Certification and are approved for competition. The advantages of the ATI SuperDamper include eliminating vibration issues with inline 6 engines equipped with lightweight clutch and flywheel assemblies, reduced bearing, engine accessories, oil pump wear, and compatibility with underdrive pulleys. Includes lightweight VAC Billet Crankshaft Pulley.
