Differential Dropouts for Dana 60, Dana 70 & More

Differential dropouts are self-contained carrier assemblies that house the ring gear, pinion, and associated bearings in a removable unit, most commonly found in rear-steer solid axles used on off-road trucks and Jeeps. Swapping a dropout lets you change gear ratios or service the differential without fully removing the axle from the vehicle, saving significant labor time.

Popular Differential Dropout Applications

Dana 60 and Dana 70 front and rear axles commonly use dropout-style differentials on heavy-duty trucks and full-size Jeep builds. Aftermarket options from Yukon Gear and Axle offer dropout assemblies pre-set with matched ring-and-pinion gear ratios for popular re-gear combinations, including 4.10, 4.56, and 5.13 options for lifted and swapped builds.

What gear ratio should I choose in a differential dropout?

Gear ratio selection depends on tire diameter, transmission gear spread, and intended use. A common guideline is to re-gear after a tire size change of two inches or more over stock. Regearing with a dropout assembly restores engine RPM at highway speed and improves low-end pulling power for towing and off-road use.

Can I install a differential dropout without special tools?

Differential dropout swaps require basic hand tools, a floor jack, and a torque wrench. Unlike full differential rebuilds, you do not need a bearing press for most dropout installations, making them a popular option for serious DIY builders.
