The axletube diameters of a Dana 44 axle typically range from 2.5 inches to 3 inches. This dimension refers to the diameter of the housing that encases the internal axle shafts, providing structural integrity to the overall axle assembly.
Understanding Dana 44 Axle Dimensions
The Dana 44 is a widely recognized and robust axle used in a variety of vehicles, particularly in heavy-duty trucks, SUVs, and off-road applications. When discussing "axle diameter," it often refers to several key measurements crucial for understanding its capabilities and compatibility.
- Axletube Diameter: As mentioned, the protective housing for the axle shafts, known as the axletube, ranges from 2.5 to 3 inches in diameter. This robust construction contributes to the axle's strength and durability.
- Ring Gear Diameter: Another critical diameter in the Dana 44 is its ring gear. The standard ring gear diameter is 8.5 inches. For next-generation versions of the Dana 44, this can increase slightly, going up to 8.8 inches, indicating enhancements in power handling and strength. The ring gear is a primary component within the differential, responsible for transferring power from the driveshaft to the axle shafts.
Dana 44 Performance Specifications
Beyond its physical dimensions, the Dana 44 is known for its impressive performance characteristics, making it a popular choice for vehicles requiring reliability and strength.
- Gross Axle Weight Rating (GAWR): For semi-floating models, the Dana 44 boasts a GAWR of 3,500 pounds. This rating indicates the maximum weight that the axle is designed to support.
- Output Torque Rating: The axle is capable of handling an output torque rating of 3,460 lb-ft. This figure represents the amount of rotational force the axle can deliver, highlighting its ability to withstand significant power demands.
These specifications collectively demonstrate the Dana 44's capability as a high-performance axle, suitable for demanding automotive applications where strength and reliability are paramount.
