3.73 ratio

The power option to my understanding just "firms" up the shift points. About the 3.73 gearing I think thats pretty standard. Mines an 88 and thats my setup also... My xj is as stock as the day it was new...

The Dana 35 had different ratios depending on other equipment like tow package, auto or manual trans.
