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

Using only three parts (a laser-welded sealed housing, an internal inertia ring, and highly viscous silicone fluid between the two), SFI-approved Fluidampr harmonic dampers can control all crankshaft vibration--not just a limited frequency range. As a result, you get reduced wear on the main bearings and timing gear, more stable valvetrain operation, and less chance of crank failure.

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

Factory dampers and non-dampened pulleys offer no protection to high performance engines. ATI Super Damper sport compact harmonic balancers 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.

Professional Products PowerForce harmonic dampers are extremely durable—and economically priced. They're built with a bonding process which adheres the elastomer to the I.D. of the inertia ring and the O.D. of the hub, utilizing a strong adhesive along with an improved elastomer to create a much stronger bond. PowerForce dampers also feature white, easy-to-read timing marks against a painted black background. Each unit is accurately balanced and closely machined for the correct fit. Dozens of models are available for applications from 1955 and up. Choose the size, material, finish, keyways, and other options recommended for your vehicle.

These Professional Products SFI Spec PowerForce Plus dampers provide more applications for a wider range of engines. All Professional Products PowerForce Plus dampers feature a bonding process, which adheres the elastomer to the i.d. of the inertia ring and the o.d. of the hub. Through subsequent research and development, Professional Products has perfected a new process that utilizes a stronger adhesive, along with an improved elastomer, to create a much stronger bond. Professional Products dampers all feature clear, white, easy-to-read timing marks against a painted black background. In addition, they engrave a mark every 90 degrees, which is also painted white (90 degree marks are not on small block Ford dampers). You won't find any dampers that are more accurately balanced or more closely machined for the correct fit than the Powerforce or Powerforce Plus line of high performance street or SFI Spec racing harmonic dampers.

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.
