What kind of differentials does an 06 dodge ram 1500 megacab 4x4 have?

A 2006 Dodge Ram 1500 Megacab 4x4 will have a Dana 60 front differential and a Dana 80 rear differential. However, there's a *possibility* of variations depending on the specific trim level and options chosen when the truck was new (e.g., towing package). While the Dana 60 and 80 are the most common, a lighter-duty option might have been available.

To be absolutely certain, you should:

* Check the sticker on the driver's side doorjamb: This will list many specifications, and might include the axle ratios.

* Look at the differential itself: The specific model number will be cast into the differential housing.

* Consult a repair manual specific to your truck's VIN: This will give the most definitive answer.

Checking the axle ratio (e.g., 3.73, 3.92, 4.10) is less crucial for identifying *which* differentials are in the truck, but it's good information to have anyway.
