Ok here is my problem. Bought all the parts needed to rebuild the front diff on my 900s got the Ring and Pinion from SATV and when I was installing it the gear ratio does not match the OEM. Called SATV and tell them the problem and they say they have never been questioned that before. We don’t have an answer for you. But yes that would be a problem here is a call tag please send it back. The stock ratio is 42 ring and 13 pinion = 3.23 ratio SATV is 42 Ring and 11 pinion = 3.82 ratio. How has nobody questioned this before? what ratio is a 1000 diff that everybody is doing the front diff swap?
