Please note, this will not work with a Fluidampr Performance Diesel Series Damper 890101, too large a diameter

Better than others

Better finish than the washer that came with my fluidampner harmonic balancer, I can find specs on this one, couldn't with the fluidampner, I emailed too, cheap insurance for made in USA parts, I like tightly controlled supply chains for special parts

ARP is good stuff

I bought this just because I was replacing everything else. A small price to pay for insurance when dealing with the balancer.
