NEW PRODUCT! Fluidampr UNDERDRIVE Crank Damper Crank Pulley For 1JZ and 2JZ Engines. We have the very first 20pc available NOW!
We worked with Fluidampr to make this product available to you! This item is great for our drifting and racing customers with a much higher redline than stock, and/or high sustained rpm. We wanted a high quality dampened underdrive crank pulley to extended the life of the power steering pump, alternator, and water pump, while also dampening harmonics that occur at very high horsepower levels. This pulley is 15% smaller diameter than stock. Since it is internally dampened with silicone fluid, there is no chance of it separating like a stock pulley can, no matter what RPM you can spin it to. We did the initial prototype testing on this pulley for Fluidampr, revving Aaron's new 1.2JZ engine to almost 10,000 rpm! These pulleys are SFI spec 18.1 certified. Fluidampr pulleys do not require honing to fit a stock crank, they install just like a stock crank pulley. They never need maintenance, and will last for the life of your engine. We have used Fluidampr crank pulleys on Driftmotion and FSR project cars for many years with excellent results. Weight: 9lbs, steel with black zinc finish.


· Broad RPM range torsional vibration protection.

· 15% underdrive accessory pulley for race use.

The hard coat anodized aluminum underdrive pulley shaves 13oz. off the standard 2JZ damper and is removable. The damper is finished in a corrosion resistant black zinc chromate, then laser engraved with timing marks, logo and SFI 18.1 credential. Last, a pre-drilled 3/8”-24 UNF on Ø3.200 B.C. bolt pattern allows for custom mandrel drives and damper installer/remover tool use.
