Titan Motorsports has teamed up with ATI Performance to release it's patened Super Damper for the Nissan R35 GTR. The Titan/ATI SuperDamper is the only crank damper designed exclusively for high performance engines to eliminate torsional crankshaft vibrations. This pulley is SFI 18.1 rated and exceeds NHRA requirements for those cars going quicker than 11.50 at the drag strip. A direct replacement for the OEM crank pulley, its black zinc chromate finish prevents rusting and allows the 360° laser engraved timing marks to be easily read.
