LSA Serpentine Drive Tensioner (6 Rib)
OEM Part Number: 12628025
This is the OEM serpentine belt drive tensioner found on all 09-15 CTS-V and 2012-2015 ZL1 Camaros with the LSA engine. It's a part often overlooked when collecting all the proper parts for an LSA swap. This tensioner will insure proper clearance between the tensioner and idler pulleys/bracket.
