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

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.

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.

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

Innovators West harmonic balancers are a great investment for your street or race vehicle. These dampers feature lightweight billet aluminum covers equipped with free-floating wet friction clutch pack assemblies that utilize spring-loaded inertia rings to dampen crankshaft harmonics over a wide rpm range. The rings work in conjunction with clutches to provide outstanding dampening action. That action does generate some heat, and Innovators West uses a small amount of fluid inside that acts as a lubricant, as well as dissipates heat to the outer body. Backed by over 25 years of experience, Innovators West has produced high-quality SFI 18.1 certified harmonic balancers employing all American-sourced materials and fasteners. Choose the model designed for your vehicle and engine application. Innovators West harmonic balancers/dampers feature: * Billet 6061 aluminum case for lower reciprocating weight * Fully scribed 360 degree timing marks * Laser-engraved part number and SFI rating on back * Premium steel internal inertia rings * Stress-proof steel crankshaft hub * OEM bolt pattern and pulley register

All piston engines produce crankshaft torsional vibration. TCI Rattler torsional vibration absorbers counteract those vibrations by using internal rollers that automatically offset the twisting forces and eliminate the root cause of torsional vibration. They are effective for the entire RPM range and extend crankshaft and bearing life while also increasing valvetrain stability. Their design does not utilize viscous fluids and they are lighter than most dampers of the same size and material construction. Rattler vibration absorbers feature steel rollers that fit loosely into a specific number of holes. By using an exact, patented, mathematical relationship, the rollers roll forward during the compression stroke and backward during the power stroke to keep engine speed variation and vibration to a minimum. The rollers are actually centrifugal pendulums that store and release energy back into the crankshaft rather than converting it to heat energy as dampers do. They are not frequency specific, but are based on the number of cylinders or the events per revolution so they are practical for street use, as well as track and drag strip use. Features include: * Standard bolt patterns * Available for internally and externally balanced engines * Etched integral timing marks can't move relative to the crankshaft * Maintains maximum effectiveness at all engine speeds * Virtually no maintenance required * No fluids, elastomers, or friction materials * No pulley or crank trigger shims required * CNC-machined to exact tolerances * SFI 18.1 certified

JET underdrive pulley sets reclaim lost horsepower and mileage by reducing the drag placed on the engine to drive the accessories, such as the air conditioning, power steering, and water pump. The pulleys slow down these accessories to allow the engine to turn with less effort without any adverse effect on the operation of A/C, power steering, charging, or cooling systems. Installation consists of simple bolt-on replacement of the stock pulleys. Kits include pulleys, hardware, complete instructions, and part number for new serpentine belt as most kits will require use of smaller size belt. Belt is not included with kit. The number and type of pulleys will vary per application.

Designed just for mildly built small block Chevys and Fords Streetdampr harmonic dampers use silicone fluid in a sealed, laser-welded housing to control crankshaft vibration at all engine rpm, just like their race-ready brothers. That means more accurate spark and valve timing and reduced bearing and valvetrain wear. About the only difference between the Streetdampr and Fluidampr is that the Streetdamprs aren't SFI-approved for racing--well, that, and their lower price tag.
