Lingenfelter ZL1 Camaro CTS-V CTSV 6.2L LSA V8 Idler Pulley Relocation Bracket



The Lingenfelter LSA Idler Relocation Bracket is designed for the LSA engine found in the 2009-2015 model year Cadillac CTS-V and the 2012-2015 model year ZL1 Camaro. It is designed to allow the installation of a larger diameter supercharger drive pulley on the harmonic balancer or damper (aftermarket multi-piece damper required). When installing 9.17" diameter or larger supercharger drive pulleys (see chart in the product pictures section) the stock idler will not have enough clearance to allow the installation.

The kit includes a black hard coat anodized 6061 billet aluminum bracket &  stainless fasteners. The kit is designed to work with the stock idler pulley or  can also be used with the Lingenfelter 76mm, 90mm or 100mm idlers. The driver’s  side (bottom) location can only use the 76mm idler.  Lingenfelter does not recommend the use of smaller than stock 50mm idlers because these small diameter idlers result in bearing speeds outside the manufacturer's specifications, often  resulting in idler failure due to bearing over speed.
