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. 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

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.

ATI Super Damper Supercharged Series Harmonic Balancers

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. 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.

Pioneer Street Performance Balancers

These high-strength, nodular-iron street performance balancers from Pioneer offer bonded balancer technology to meet the budget of every performance street engine builder from mild to wild. They also make great heavy-duty standard replacement balancers and are perfect for limited-spec race classes, such as late model stock, that require an OE-style balancer. The bonded dampening rubber in these balancers eliminates spinning and component separation, giving reliable performance in engines using up to 6,500 rpm. All Pioneer street balancers feature easy-to-read, permanently etched timing marks on the outer ring.
