Description

ATI Super Damper Serpentine Series harmonic balancers are patented and feature grooves for serpentine belts machined into the outer damper shell. The dampers come with six outer grooves for standard OEM drive systems—but eight and 10 grooves are available for supercharger or turbo applications. Serpentine dampers are offered in a variety of diameters, and crank hubs may be fitted with a 6-groove serpentine pulley to drive external oil pumps or vehicle accessories. The Serpentine Series Super Dampers fit all ATI GM-front crank hubs and can be adapted to many engine combinations, providing maximum flexibility. They're available in steel or lightweight, hardcoated aluminum.

Features and benefits:

* Eliminates torsional crankshaft vibrations
* Exceeds SFI 18.1 specs
* Black zinc chromate finished
* Tunable, rebuildable, and extremely efficient at all rpms
* Laser-engraved 360 degree timing marks
