10-Rib Grooved Guarded Idler Pulley

The Whipple 10-Rib Grooved Guarded Idler Pulley, with its 3.50-inch running diameter, is engineered to provide added belt guidance for Whipple supercharger belt-drive systems that utilize a 10-rib configuration. This component features a single high-speed bearing and a robust guarded design, crucial for keeping the supercharger belt properly aligned, especially in demanding marine and high-performance scenarios. Constructed with durability in mind, this idler pulley is available in three finishes: black, blue, and clear anodized. It is a common component in Whipple marine big block supercharger systems and other related belt-drive setups. For optimal performance and fitment, it is always recommended to verify the pulley diameter, rib count, belt routing, and any necessary mounting hardware requirements before installation. Mounting hardware is not included with this pulley unless specifically requested. It is also specifically mentioned for use with the WK-1010-30 Supercharger kit and has been listed for 2016-2024 Chevy Camaro LT1 applications. Additionally, it is noted for use in various MerCruiser and 496 Magnum applications, as well as universal Whipple Marine Big Block kits and Teague Whipple supercharged engines.
