60 And 14 Bolt Ring Gears

9 of 16
The 14-bolt is more massive than the 60 in almost every way. The 60's ring gear is 9 3/4 inches in diameter (left); the 14-bolt's is 10 1/2. In two major ways, the 14-bolt is actually more comparable to the Dana 70 than to the 60. Both the 14-bolt and the 70 have 10 1/2-inch ring gears, and the 70's normal axleshaft diameter is 1 1/2 inches, which is close to the 14-bolt's 1 9/16 inches. So why not compare 70s and 14-bolts instead? Because when you look at a 3/4-ton 4x4, you're looking at either a 60 or a 14-bolt. The 70s ran on 1-tons and very rarely on 3/4-tons and are less common. There are also fewer lockers and gears available for them.
