ATI Pulley Assy - Idler - 100mm - 8/10 Grv - Double Bearing

This is the ATI 100mm idler pulley assembly, part number ATI916208-100. It's designed with an 8 or 10 groove configuration and features a double bearing setup for added durability and smooth operation. This pulley is a key component in your engine's accessory drive system, helping to guide and tension the serpentine belt.

Built by ATI, a well-known name in performance engine components, this idler pulley is constructed to handle the demands of a running engine. The double bearing design helps to distribute load more evenly, which can lead to a longer service life compared to single bearing units, especially in applications where belt tension is high or the engine sees frequent use. The 100mm diameter is a specific size that ensures proper belt alignment and tension within the accessory drive system.

When you're working on your engine's accessory drive, ensuring all components are in good working order is important for the overall health of your engine. This ATI idler pulley is a solid option for replacing a worn or damaged unit, helping to maintain proper belt function and prevent premature wear on other components in the system.
