High Performance Race Dampers

Our Race Dampers are made from bulletproof 1045 steel. These dampers are designed to be installed on race engines that may rev over 10,000 rpm. Optimum damping occurs in the 6500 to 7500 rpm range. The machine work on these dampers is second to none and the critical fit tolerances and balance are held more closely than OEM. All externally balanced dampers feature bolt-in counterweights. This feature allows for swapping weights between dampers (Ford) or adding them to internal balanced dampers (Chevy) if you change applications. The basic damper in any family is the same with either a different counterweight (Ford) or an added counter- weight (Chevy). This provides an unlimited amount of flexibility. Plus, you can't buy a more accurately balanced damper.

Note: All small block Ford dampers are made to the shortest (as measured from the front the engine) length as used on '79 & earlier engines. Spacers are used to move the front face out to provide correct pulley alignment on later engines. See note under adjacent Street Damper listings. This feature allows you to install a late engine in an early vehicle and use the stock pulleys and drive arrangement. All our Ford units have both three and four bolt hole patterns and when used without the spacer, are the correct length for early model vehicles.
