The ATI Super Damper for Evo X is available in two versions. The Street version offers a 3% under-drive for improved dampening and increased power and is a direct OEM replacement. The Race version offers a larger diameter and no belt drives.

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 360° laser-etched timing marks and exceeds SFI 18.1 Safety Certification.
