Description

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.

For this reason, many sanctioned race classes require an "SFI Approved" crank pulley/damper, and will not even allow factory crank pulleys through inspection. 

The Evo X damper is offered in a 3% under drive (p/n 918253) for improved dampening and increased power. Unlike unbalanced underdrive pulleys, which offer no protection to high performance engines, the ATI Super Damper provides balanced dampening of torsional crankshaft vibrations. The 3 external bolts allow for the mounting of A.R.E.'s dry sump mandrel to the damper (A.R.E. p/n 2750B).The ATI damper comes with 360Âş laser-etched timing marks and exceeds SFI 18.1 Safety Certification.
