I don't think they have an LS1 app yet, but they were great for SBCs.

Fluidamper doesn't have an LS1 application, but there are fluid type dampers available as a lower cost alternative to the ATI damper.

The only place I've seen them is a guy that sells them on eBay. They are manufactured by a company called Cal Auto Transpeed, and are SFI 18.1 approved (for 10.99 and quicker). I have one waiting to go on my motor when I finish putting it back together. It appears to be a pretty nice piece for the money... FWIW, you don't get SFI approval on just anything, so it can't be too bad (has to be tested to 13,500rpm for SFI certification).

Also, Jeg's is now selling a "house brand" SFI approved LS1 balancer, although I don't believe it's a fluid-type damper...

JMHO...

so the one you have is off e-bay?
dose it come with belts are use the stock ones?
thanks for the info

It's a stock diameter pulley, and uses the stock belts.

I don't need an underdrive, since all I drive off the crank pulley is the alternator...
