Why use OADTM pulleys? Because they provide….

  • Extended belt life and increased drive system component durability (up to 2x)
  • Extended tensioner life. Meaning alternator, water pump and other bearings will last much longer
  • Smoother and quieter accessory drive system operation
  • Reduced vibrations in passenger compartment
  • Improved fuel economy (1-2% - depending on application) due to reduced friction in the belt drive system

Always replace OE pulley technology with the same aftermarket technology. Therefore, you are safe purchasing OADTM pulleys from HC-CARGO.
