It is the billet steel FW by SLP. It is SFI rated.
It fits the 1998-02 LS1 and weighs 8 lbs. less than the stock cast iron flywheel.
But it isn't aluminum.
That said, aluminum may not be the best FW for a particular application. If a car is used for any type of drag racing or even auto cross, the steel one may be a better fit. Same for a purely street car, as the revs really drop between the shifts and this can be aggrivating for normal driving.

stupid question - al or steel? If aluminum, your check is already in the mail.
