• 32 Spline vs. the stock 10 spline

• Tremendous increase in trail reliability.

Tech Notes 1.  Overall assembly will be 3/4" longer than stock.  It is possible but not likely that the rear driveshaft will need to be shortened 2.  The system includes a 1310 series CV style yoke.  This means it will bolt up to your stock spicer style driveshaft  (If you are running the old Borg Warner style driveshaft it will need to be changed to a Spicer style).  See below for driveshaft identification. 3.  The Extreme Duty Dana 20 Output System bolts into the stock Bronco Dana 20 output housing.  No modifications to the housing are necessary.

Driveshaft Identification
          From 1966-70, the Bronco came with a Borg Warner driveshaft and, from 71-77, they used a Spicer.
          Both of these styles used constant velocity joints. If you're not sure, don't go by the year because many
          of the old ones have been updated already. An easy way to tell which you have is to see if your
          driveshaft uses external snap rings (Spicer). If you can see the snap rings on the outside of the bearing
          cap, it's a Spicer. Another way to tell the difference is to measure the bolt pattern on the transfer case
          yoke. All of our driveshafts are Spicer style and you will need a transfer case yoke if you are converting
          from the old Borg Warner style.

There is a 100.00 Core charge for your old assembly. Broken shafts accepted.
