These dampers will not fit 1996-'97 LT4 Corvette and Camaro or 1992-'96 LT1 Corvette. These dampers do fit 1993-'97 LT1 Chevy Camaro, Pontiac Firebird, 1994-'95 Chevy Caprice, Impala, and Buick Roadmaster. To identify an LT4 from an LT1, the LT4 VIN number has the eighth digit as a "5" and the LT1 has it as a "P." Both of these dampers include a high strength steel hub, spacers for various engine applications and high quality damper to hub attachment bolts in two different lengths. It is highly recommended to use a new factory crankshaft bolt, GM #9440024. Both dampers have a keyway and a supplied key plus 60° of timing marks. The stock damper does not use a key, but the crank has a keyway in it. For high performance applications, use of the key is recommended.
