ATI Super Damper Serpentine Series Harmonic Balancers

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.

PowerBond Race Performance Harmonic Balancers

PowerBond Race performance harmonic balancers bring the advantages of bonded balancers to high-revving and high-horsepower street/race applications where an SFI-approved balancer is required. They have been tested beyond 21,000 rpm without failure, and every balancer features a precision CNC-machined AISI 1045 forged steel hub bonded to an equally strong steel inertia ring. They are very light and in most cases, they are only marginally heavier than the original cast iron balancer. The steel inertia ring on the Race Series models is positively protected against forward and backward movement. PowerBond uses our Race Series high-pressure, low-cure that features a natural rubber developed in our laboratory. Every model has easy to read computer etched timing marks and meet SFI specification 18.1.

Fluidampr Harmonic Dampers

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.

Innovators West Harmonic Balancers

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
