Toyota 10.5" ring gear...

GreenSlime,

Thanks for the heads-up with regard to the hypoid angle. As I understand it, Ford created their 9" with an unusually low hypoid angle, to lower the driveshaft in order to minimize the size of the hump in the rear floor.

A pickup truck wouldn't have that consideration to deal with, so, hopefully, this Toyota rear end will have the pinion gear located in a more advantageous location on the ring gear.

Oklacarcollecto and camd64, thanks for that information. A 4.30 would be a good ratio for a lot of street-strip cars; mine only needs a 4.10.

But, of course, serious race cars are going to have to have aftermarket support from Richmond, or somebody like that, to utilize these units. Ratios have to be available up into the high "5"s, at least, to be practical for high-rpm motors in 3000-pound cars.

Sure would be cool if the DO gave a dropout center section. I'll go look at one, tomorrow.

I guess only the V-8s have this rear end.
