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

ATI offers two different versions of their bolt-on style SFI bellhousings, including ATI SFI Standard bellhousings. The Standard versions bolt onto the face of the pump and the case finish is not as critical. The direct-fit versions indicate on the outside diameter of the pump and require precise machining. When you want the standard-style, choose the ATI SFI Standard bellhousing best suited for your application.

Patented ATI Super Damper standard harmonic balancers are the only crankshaft dampers designed exclusively for high performance engines. Inner and outer shells are available in aluminum or steel, and contain a steel inertia weight. The inertia weights have six (2-ring design) or eight (3-ring design) computer-machined grooves to retain the proper durometer O-rings (dyno tested for each application). Whether you race or just drive on the street, ATI harmonic balancers are the perfect choice. Features include: * Eliminates torsional crankshaft vibrations * Exceeds SFI 18.1 specs * Black zinc chromate finished * OEM equipment on a variety of crate engines * Tunable, rebuildable, and extremely efficient at all rpm * Laser-engraved 360 degree timing marks * Supercharger and power steering drive pulleys available for some applications

These Supercharged series dampers place the powerful protection of ATI Super Damper inside of the crankshaft blower pulley. Available in 66 to 77-tooth 8mm pitch, and 40 to 51-tooth 14mm pitch, these balancers eliminate torsional crankshaft vibrations and feature dual-keyway hubs. These balancers exceed SFI 18.1 specs, have laser-engraved 360 degree timing marks, and are finished in a black zinc chromate. Numerous pulley offsets are available to keep the blower drive as close to the engine as possible, reducing the bending moment to the crankshaft nose.

ATI Superplate Flexplates were developed in ATI's tradition of staying ahead of the rampant increases in horsepower that are common in the performance industry today. Superplates are manufactured from a super-strong material to withstand thousands of cycles. They are laser-machined rather than stamped to avoid the heat and stress stamping inflicts. The crank bolt holes are bored in position to exacting tolerances in both size and location on CNC machines. Superplates use the grip length of the crank bolts as dowels to prevent the plate from moving under high-torque conditions. Unlike billet plates that violate the "flex principle" of a flexplate, Superplates flex like OEM plates, absorbing the numerous machining tolerances that exist in our non-exact world. Additional features of ATI Superplate Flexplates include: * Neutral-balanced for use on internally balanced engines * Exceed SFI 29.1 and 29.2 ratings * 90,000 lbs. tensile strength * 80,000 lbs. yield strength * Six or eight crank bolts (varies by application)
