Anybody ever use one of these?

I know, Chinese junk. But doesn't replacable counterweights seems like a great idea? One balancer for all small blocks? Looks like there's an SFI rated version as well...


nope sounds more like cheap than a great idea realy. after seeing what happens when a cheap damper blows apart i will never buy a cheap one,the one i say literaly blew apart sending one pretty big piece of iron into a framerail making a pretty good dent and another piece smashed thru the outlet fitting on a fuelpump taking it cleanly of the pump,good thing no fuel ended up in a hotplace that could have got real ugly,this was on a pretty good running sbc that was always run with a rpmlimiter at 6000rpm
