This convenient kit includes three popular pulleys we manufacture for the GM LSA application: Our oversize supercharger idler pulley for added belt wrap, our heavy-duty replacement for the tensioner pulley on the supercharger drive, and our heavy-duty replacement for the tensioner on the accessory drive. These three pulleys install as direct replacements for the OEM pulleys and no modifications are required. Even the existing belts (supercharger and accessory drive) can be re-used.
If you prefer, each of these pulleys is available separately and is listed elsewhere in this section.
Shown from left to right in image 3, above: Supercharger tensioner pulley: MTP-LSA, Accessory drive tensioner pulley: MIP-2010, Supercharger idler pulley: MIP-100V
Note: In Camaro ZL1 applications using our MRB1000 pulley relocation bracket, the 87mm accessory drive tensioner pulley must be swapped with the 76mm idler from the driver's side of the engine. This kit can be configured with a matching 76mm idler pulley instead of the 87mm pulley for the same cost. Please call or email for details.
