Professional Product"s Powerforce and Powerforce Plus dampers for the extremely popular LS1 engine represent one of the best values available in the high performance industry. These are very high quality dampers at affordable prices. This damper will also work on most LS1 based crate engines. Although not required on a stock engine, our dampers have a keyway and 60 degrees of timing marks. This damper is dimensionally identical to the stock O.E. damper.
Fits LS-1 and LS-6 Camaro, Firebird and Corvette. The 80032 and 90032 may also fit certain 4.8L, 5.3L, and 6.0L G.M. engines. The 80032 and 90032 models fit 1998 and later Camaro and Firebirds (and possibly some other G.M. models equipped with this engine or variations of it). The 80033 and 90033 fit the LS-1 and LS-6 engines used in the 1997 and later Corvette. The only difference between the 80032/90032 and the 80033/90033 is that the Corvette model is 0.852" shorter than the Camaro/Firebird model. Other than that, they are essentially the same.
