4. The housing ends we chose are aftermarket versions of factory Ford 9-inch ends that accept Set 20 axle bearings, also referred to as “Torino” or “big-bearing” ends. The ends were designed to slip inside a typical Ford 9-inch housing, which has much thinner axletubes than our heavy-wall Dana 60. As a result, Draper had to cut off a lip machined on the ends using a lathe. This lip is really just for indexing and has no impact on overall strength.
