anyone know what gear ratio is the stock ford diff, all i know is it is the ford 7.5" diff on my truck, anyone know whats the highest gear size i can put in it?

i :read: that if its smaller than like 3.78 than ill have to get a new case to put anything bigger than 3.78, say a 4.10 or 4.56.

also , was wondering if anyone knew what gear ratio is in that diff

Frankly I wish their site was easier to find parts and I wish he posted prices. I don't like having to call.

Are you using a gasket or silcone?

The 28 is silcone and the 7.5 is a gasket

Most likely you got 3:73's . In the door jam there is a white sticker has vin # type stuff on it. on that ther is a axle code get the number and we can figure it out. Mine had a L6 it was a limited slip 3:73. and if you need something let me know I got 3 axles laying around.
