440 source harmonic balancer?

Are the balancers they sell certified to run in the 10's by NHRA standards? Also what proof do you need @ the track that shows that your balancer complies?

Part No: 200-1023 - SFI Fluid damper - Chrome - New. Price: $134.95 is the only SFI approved balancer listed on their site.

If it doesn't state in the product description that it IS SFI approved than you must assume that it isn't.

Every SFI approved balancer that I have seen has a label on it with the SFI info.

You can get that same balancer in black from brandon @ 440source, Thats the one I bought last year, but no SFI Lable! no lable on there chrome one either from the pics i see on there web sight.

It won't pass tech without a label.

Might want to get a hold of Brandon if the one you have is supposed to be SFI approved.

I bought a chrome one a few years ago,the sfi info was stamed int the surface similar to the timing marks.I would have assumed that the black one would be the same,but??
The stamping is hard to see,but the required info was there(on mine anyway).

The chrome one come with a label....at least mine did.
It also has the "A" number inscribed into the balance face as well.....and THAT is a good thing, because after a few wash downs with brake'clean because of a persistant oil leak, my label flew off somewhere at some track.
I was wondering about a tech guy not seeing my label and getting a hissy-fit, but the numbers are etched in the damper....I guess he could get picky... couldn't he.
