Hey, im hopeing you guys can help me out. Im looking to do a rear end swap in my '88 ranger. Before i can start getting excited ive got an amature question :icon_confused: I need help figureing out what the gear ratio is in my current diffs. ive got the codes from each:

Rear- AS308B 73 75 9F02

Front- 3 73 VE87A V610307 2

im guessing that because my front one says 3 73, then thats the gear ratio?

If you can help me that would be very much appreciated!

Thanks! :icon_cheers:
 
Yup, you got it right. I'm guessing there was a 3 in front of the 73 in the rear number as well, but it could have been flattened out or scraped away.

there is some information about the axle tags for you. The Tech library link above holds t his and all sorts of good stuff about the ranger :)

from your tags, it looks like you have an open carrier 3:73 7.5 axle on the rear (take a close look at that tag again, and I would imagine that it is AS3083 73 75 9F02), and your front looks like it is another open 3:73 Dana 28.

hope this helps.

Go for the Explorer 8.8 swap. It's a bit higher on the difficulty scale, but 3.73 geared exploders were about as common as corn on a farm.
