DANA 30
The Model 30, with a 7 1/8-inch-diameter ring gear, was the standard front differential in some 1972-75 CJ-5s and all 1975-and-later CJ-5s and CJ-7s. It is still used in the front of Cherokees and Comanches, and will probably appear in the front of the Grand Cherokee.

DANA 41
The 41, which has a ring gear size similar to the Dana 44, came in early CJ-2As. The spiders are the same as a 44's, but the carrier and gears aren't. It is almost universally swapped out in favor of a Dana 44.

DANA 44
All domestic manufacturers have used Dana axles, and the 44, with its 8 1/2-inch ring gear, is likely to be a step up on anything smaller than a 1/2-ton. A narrowed 44 could be the hot ticket for vehicles smaller than a full-size sport-utility. It was standard under the front of pre-1976 Chevy Blazers and 1/2-tons, solid front-axled F-150s and Broncos, and Jeep J-10/J-20s and Grand Wagoneers.

DANA 44-IF
The Ford-version Dana 44 Twin-Traction-Beam setup is similar to other 44s (ring gear diameters are identical), but there are no axle tubes and the "cover" is actually the suspension arm. It's standard in the front of any TTB-equipped Ford except the F-250HD, which uses a Dana 50.

DANA 60
A Dana 60 looks deceptively similar to a Dana 44, but the 60's 9 3/4-inch ring gear diameter is a major factor in strength. It can be found in many 3/4-ton pickup and van rear ends.
