ATI Race Super Damper Crank Pulley 3.3lbs with Aluminum Hub Acura Honda B16 B17 B18 B20

Much like many other factory parts in your engine, the crank pulley is a wear-item with a shelf-life. The rubber pieces in the factory damper can deteriorate over time, causing a failure that could result in pistons hitting the valves, and destroying your engine. Also, factory crank pulleys were designed to operate at a certain speed and maximum rpm. When racing an engine, we often rev it higher than it was designed to from the factory, pushing many of the factory parts past their design criteria closer to failure.
ATI’s 7” and 6.325” race versions are built with all-out power in mind. You won’t find drives for A/C and power steering here. The alternator drive is built into the hub with laser engraved 360° timing marks on outer damper shell. 

Not for over 300 horsepower - damper has lightweight inertia for clearance!
