5.0 Instant Traction

I had this locker installed in my Dodge Ram Dana 60s, both front and rear, in the fall of 2008 and have zero complaints or complications. I upgraded my shafts to 35 spline units at the same time to avoid future costs and get ultimate strength. Adding a selectable locker like the ARB gives you instant traction when needed and the convenience of unlocking the unit for better turning radius, less wear/maintenance and maximum control. For vehicles that drive on pavement, this means less tire wear, no chirping, less axle shaft stress and safer operation in low traction situations (ice, rain, etc.) No special diff covers or complicated cables or levers!

Question & Answers

Q: What set 5.13 ring and pinion can be used with this carrier? It is going in a 2017 F250 front Dana 60 short pinion reverse cut. All the gear sets say to use a 4.10-down carrier. Thanks! Answer this question

A: In 2017 the Ford F250/F350 received a new Dana 60 SHORT Pinion High Pinion front end. This front requires a 4.56 and numerically higher carrier such as the ARBRD166. It will require a Short Pinion High Pinion type ring and pinion which is only made up to a 4.88 ratio. This new front end uses different pinion bearings and associated parts on the pinion than the earlier Dana 60 front end. The 2017 F250 can be equipped with a 12 bolt Sterling 10.5” rear end which can be regeared to a 4.88 ratio to match the front. Some of the heavier GVWR 2017 F250 trucks have the larger Dana M275 rear diff and the highest numerical ratio is 3.73.
