Gates Super Duty Accessory Belt Tensioner

The Gates Super Duty Accessory Belt Tensioner is a drive belt tensioner designed for heavy-duty applications. It keeps the proper tension on the serpentine or accessory drive belt, so the alternator, water pump, power steering pump and A/C compressor keep turning reliably. Gates also sells related parts under the names automatic belt tensioner and serpentine belt tensioner.

Key Features:

• Heavy-duty construction built for demanding service and long life
• Maintains consistent belt tension to reduce belt slip, noise and premature belt wear
• Helps dampen belt vibration for smoother accessory drive operation
• Engineered by Gates, a long-established name in belt drive and power transmission components
• Designed as a direct replacement for the original tensioner

Replacing a worn tensioner along with the drive belt helps prevent squealing, belt damage and accessory failure. Choose the specific part number you need from the variants listed on this page.
