Gm 14 Bolt Big Pumpkin

Back to article View Gallery
10 of 16
The 14-bolt's bigger pumpkin provides less ground clearance than the smaller 60's. And 60s are available in high-pinion versions too, whereas 14-bolts are not. High-pinion 60s were used as front axles and are custom-built to work as rear ones. The high-pinion design, in which the pinion shaft enters above the axle centerline, becomes important to correct driveline angles in some short-wheelbase 4x4s with short driveshafts.
