Marine Harmonic Balancer
Big Block Chevy V8 Externally Balanced, 8" Diameter

• Material: Steel
• Finish: Black Zinc
• Keyway: Single (3/16")
• Bore Dia. Min/Max: 1.599 / 1.600
• Degree Marking Range: 50 BTDC to 10 ATDC
• OD: 8"
• Length: 2.75
• Engine Balance: External

The inertia ring inside Fluidampr shears through a thin film of highly viscous silicone fluid to effectively control harmonic vibration at all engine speeds. Silicone fluid is a very good damping medium because it is relatively unaffected by temperature changes. Thus, it provides consistent damping in both winter and summer. The fluid does not harden or change viscosity if Fluidampr is not used for a period of time. The fluid is so durable that big rig, 18 wheeler truck engines are mostly all equipped with viscous fluid-type dampers. Silicone fluid’s damping capability is unmatched. That’s why the fluid inside Fluidampr is guaranteed for as long as you own it.

You can't feel them or hear them, but harmonic vibrations are at work inside every internal combustion engine. That's not good. Similar to glass-shattering forces created by a high pitched note, harmonic vibrations cause metal fatigue and can cause significant power loss because crankshaft harmonics are transmitted to the camshaft and valvetrain. Control this power-robbing force with a Fluidampr harmonic damper that uses race proven vibration damping technology. A high viscosity silicone fluid surrounds a nylon-coated inertia ring inside a laser welded housing. All dampers are coated with a black zinc chromate finish for increased corrosion resistance. Timing marks - every two degrees from 50° BTDC to 10° ATDC with additional marks at 90, 180 and 270. Meets SFI 18.1 specs. Made In The USA.

Fluidampr Int. Harmonic Balancer GM / Chevy 6.2L LT4

• Crankshaft torsional vibration protection across RPM range. 
• Reduce risk of crankshaft failure & wear on critical engine parts. 
• Unleash lost torque and horsepower. 
• Replaceable crankshaft hub. 
• SFI 18.1 certified.
• Made in USA.

The steel damper is finished in a corrosion resistant black zinc chromate, then laser engraved with a Fluidampr – Made in the USA logo and SFI 18.1 credential. The front and rear bolt-on Supercharger and air-conditioning aluminum pulleys have a hard coat anodized finish.

Timing Pointer for Use with Hardin Serpentine Drive Kits

Designed to hug the damper so it is easier to line up the damper and the pointer for more accurate timing. Up to 4 degrees of adjustment are possible. Constructed of billet aluminum with a black anodized finish. Stainless steel mounting hardware included
