Professional Products 8" SBC 350 Harmonic Damper

350 SB Chevy Harmonic Damper diameter. These are both terrific all around high performance dampers. The 80002 makes a great damper for high performance street applications, and the 90002 is the choice for racing when you want maximum damping to protect the rotating parts as well as the timing gears, timing chain and valve train. Optimum damping means your engine will run as smoothly as possible, and you are getting accurate valve timing. An improperly dampened engine can result in premature crank failure, as well as incorrect valve timing, thus robbing your engine of power. The Powerforce street model is very similar to the much more expensive G.M. Performance malleable iron 8-inch damper except ours is made of stronger nodular iron with more timing marks.
