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.

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
