Gates DriveAlign Belt Drive Idler Tensioner Pulley Pulleys

Gates DriveAlign idler and tensioner pulleys are replacement belt drive pulleys for serpentine and accessory drive systems. They guide the belt and help keep it properly tensioned, so it transfers power reliably to the alternator, power steering pump, water pump, and air conditioning compressor. Depending on the application, the line includes both idler pulleys and tensioner pulleys.

Key Features:

• Precision-engineered design: Built to hold accurate belt alignment and to help reduce noise, vibration, and uneven belt wear.
• Durable bearings: Sealed bearings are designed for long service life under the heat, load, and contamination found in an engine bay.
• Quality construction: Pulley bodies are made for strength and stable running, so the belt tracks smoothly.
• Multiple pulley styles: Flat and grooved (ribbed) idler and tensioner pulley styles are available to suit different belt drive layouts.
• Trusted brand: Gates is a well-known name in belts, hoses, and belt drive components, with a long record of supplying OE and aftermarket drive systems.

Replacing a worn idler or tensioner pulley when you change the drive belt helps prevent squealing, belt slip, and premature belt failure. It also helps keep the accessory drive running as designed. Select the specific part number for your application to get the correct pulley configuration.
