DMS 76mm LSA LS9 Supercharger Idler Pulley
The DMS 76mm idler pulley is commonly used on the LS9 belt system to help establish the proper belt length/tension. These pulleys are made out of 6061 billet aluminum, anodized black and comes standard with a pair of Italian made high speed bearings. We use a Spirolox bearing retainer to maintain balance at high speed. Also included is two bearing spacers designed to be used with the factory bolt for ease of installation.
This pulley is 42mm wide allowing the use of up to an 11 rib belt. Pulley offset works on the LSA and LS9 supercharger belt drive system.
