"Lightened" Ford 9" Gears

Hey guys-

I was looking at some Ford 9 inch gears on Ebay that have been lightened by removing some of the material on the opposite side of the teeth on the ring gear (please see associated Ebay listing http://cgi.ebay.com/ebaymotors/ws/eB...K%3AMEWAX%3AIT

According to the listing seller they are used (about 300 miles on them)gears from a NASCAR team. Would these gears still be good to go for a street / strip rod powered by a SBC? I guess I just do not know how much weaker the gears are after they are lightened? According to the seller they are also Strange brand gears. Thanks for any input.

Brent

Thr gears are not really any weaker after this has been done, it is only done to reduce rotating mass on a circle track car. Would be fine for most street cars, but I would question using them in a fast drag car because of the higher shock loads.

Eric,

Thanks for your reply. I would expect that this car will never go faster than 11 secs in the quarter, so I am hoping these will work. The vehicle they are going in definately will not be one of those sub 10 sec rods.

I would expect you to be fine as long as a transbrake or clutch dumps with slicks aren't involved and like you said, not sub 10-second ET's.

If it was done correctly,they will hold up just as good as if wasn't lightened. I've used the strange lightened set's for big HP car's with big tires,trans brakes and they held up to the hard hits.
