Are you looking for maximum engine protection and performance for your serpentine belt application? These ATI Super Damper serpentine harmonic balancers contain grooves for serpentine belts machined into the outer damper shell.

Factory dampers and non-dampened pulleys offer no protection to high performance engines. These ATI sport compact Super Dampers provide the balanced dampening of torsional crankshaft vibrations at all rpm levels. The street versions have both OEM serpentine groove locations and are very close to OEM size. The smooth-shell race version dampers are designed for high performance race use. Both dampers come with laser-etched timing and exceed SFI 18.1 Safety Certification standards for competition use.

The patented ATI Super Damper is the only damper designed exclusively for high performance engines.

Damper includes new billet aluminum water pump pulley for clearance. AC is a 25% OD. Do not use a belt if racing! 3% UD power steering, 10% UD for alternator.
