COMP Cams Valve Locks Hi Perf For Gm LS

These single groove Machined Steel Street Locks with 7? lock angle and 8mm valve stem size are perfect locks for GM Gen III/LS1/LS2/LS6 applications. It is critically important to make sure valve locks match the valve size. There should always be a small gap between the two halves of the lock when they are properly positioned on the valve stem. If the two halves fit together without a gap, they are too large. If the locks fit tight to the stem and leave a gap between the middle of the lock and the O.D. of the stem, the locks are too small.User 1CatalogWarrantyCatalogThis Part Fits: Year Make Model Submodel 2004-2007 Cadillac CTS V 1998-2002 Chevrolet Camaro Z28 1998-2002 Chevrolet Camaro Z28 SS 2003 Chevrolet Corvette 50th Anniversary Edition 2003 Chevrolet Corvette 50th Anniversary Edition Pace Car 1997-2007 Chevrolet Corvette Base 1998 Chevrolet Corvette Indianapolis 500 Pace Car 2001-2004 Chevrolet Corvette Z06 2006-2007 Chevrolet Impala SS 2006-2007 Chevrolet Monte Carlo SS 2005-2006 Chevrolet SSR Base 2006 Chevrolet Trailblazer SS 1998-2002 Pontiac Firebird Formula 1998-2002 Pontiac Firebird Trans Am 2005-2007 Pontiac Grand Prix GXP 2004-2006 Pontiac GTO Base
