The Dana 80 is a heavy-duty rear axle manufactured by Dana Incorporated. It is commonly found in heavy-duty pickup trucks, vans, and chassis cabs, typically those with a Gross Vehicle Weight Rating (GVWR) exceeding one ton. The Dana 80 is known for its robust design and high torque capacity, making it suitable for demanding applications such as towing and hauling heavy loads.
Key features of the Dana 80 axle often include:
-
Full-Floating Axle Shafts: This design carries the vehicle's weight on the axle housing rather than the axle shafts themselves, reducing stress on the shafts and making them easier to replace if damaged.
-
Large Ring Gear: The ring gear is typically larger than those found in lighter-duty axles, contributing to increased strength and durability.
-
High Torque Capacity: The Dana 80 is designed to handle significant amounts of torque, making it suitable for vehicles with powerful engines and high towing requirements.
-
Variety of Gear Ratios: Dana 80 axles are available with a range of gear ratios to optimize performance for different applications and engine types.
The Dana 80 axle is a popular choice for vehicle manufacturers and aftermarket modifiers seeking a durable and reliable rear axle for heavy-duty applications.
