ATI Pulley Assy - Tensioner - 8 Grv - Double Bearing

This is the ATI 8-Groove Tensioner Pulley Assembly, featuring a double bearing design. It's a key component in your vehicle's serpentine belt system, responsible for maintaining the correct tension on the belt as it drives accessories like the alternator, power steering pump, and air conditioning compressor. Keeping the belt properly tensioned is crucial for ensuring all these components operate efficiently and reliably.

ATI builds this tensioner pulley with a double bearing setup, which helps distribute the load more evenly and can lead to improved durability compared to single bearing designs, especially under demanding conditions. The 8-groove design means it's ready to work with serpentine belts that have eight ribs, common on many performance or modified applications where more accessories might be driven. This pulley is designed to fit right into place, making replacement straightforward for those familiar with serpentine belt service.
