The Blower Drive Service Aluminum 3-Inch Idler Assembly (IP-9451) is a precision-engineered supercharger idler pulley designed for high-performance engine builds requiring Gilmer or HTD belt compatibility. This component delivers the pulley contact geometry and rotational stability necessary for consistent boost delivery in supercharged applications.
Constructed from aluminum and finished with a polished surface, the IP-9451 idler assembly weighs 2.59 lbs and measures 5.45 x 4.85 x 10.25 inches. The precision bore and mounting interface maintain tight tolerances critical for idler pulley function, ensuring proper belt tracking and load distribution across the pulley face.
This idler assembly is specified for supercharger kits and belt-drive boost systems where OEM or worn pulleys require replacement. Builders upgrading to larger displacement superchargers or restoring vintage forced-induction systems will benefit from this reliable component.
