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.
