Ask a question about this product

Professional Products' 8 inch damper is unique in one respect, It is the only damper not made to the original factory diameter. The original 396/427 dampers were 7 inch in diameter from G.M. When the 454 came out, G.M. switched to an 8 inch damper. Although this is listed as a 396/427 damper, it will also work on any displacement big block engine that has a neutral balance rotating assembly. These dampers have 60 degrees of easy to read timing marks plus engraved marks each 90 degrees of the circumference.
