Wondering if Ofna changed some gearing?...this is from the Ofna Racing site showing pictures and details and this is the last one down the line:" 43 Tooth Ring & 13 Tooth Pinion Gear (3.30:1)" Maybe I don't understand what the "differential ratio" is of 3:30 to 1,(43t and 13t). Can someone explain for me? Thanks,Huck

The manual shows that it is a 43T spur and a 13T pinion.
Looking further down in the parts section, it shows a 13T bevel shaft pinion and a 43T bevel diff ring gear.
The FDR (Final Drive Ration) is as follows:
FDR = (Spur / Pinion) X (Ring gear / shaft pinion)
= (43 / 13) X (43 / 13)
= 3.3 X 3.3
= 10.6
