What is the best axle material?

As the horsepower of the vehicle increases and subsequent wheel torque is generated, stronger materials like SAE 1550 or 4340, or even a more exotic 300M, are needed for extreme-duty axle shafts. The SAE 4300 series material is referred to as a high-strength low-alloy material.

What is a high pinion vs low pinion?

A low-pinion axle positions the pinion below the centerline of the axle, while a high-pinion axle places the pinion above the centerline of the axle. The OEMs have used both styles in solid front axles over the years in many different solid-axle applications.

What does a Dana 80 come in?

ID A Dana 80 Rear Axle in Chevy, Dodge Ram, or Ford Truck IDN-126. Was: Dana 80 Rear Axles have been in production since the 1988 Model Year. They have been used in Chevy/GMC 1992-2002 , Dodge(1994-2002), and Ford (1988-current) trucks vans, and motorhome chassis.

How much stronger are chromoly axles?

1541H can be 50 percent stronger than OE 1040 and about 12 percent stouter than 1050. 4140: 41xx designates the chromoly group. Chromium offers three benefits: improved hardness, better elasticity during quenching, and greater corrosion resistance. Molybdenum and nickel further increase hardness.

Are axle shafts hardened?

Axle shafts are typically case hardened using induction. In this process, the surface layer of a steel component is heated to form austenite, and then spray quenched to form martensite. The result is a hardened layer that is under residual compression and a core that is under residual tension.

Is Ford 9 inch high pinion?

This is why Ford, Toyota, and Jeep have used high-pinion differentials in the front of their vehicles for decades. Meanwhile the Ford 9-inch is incredibly light and strong, making it the axle of choice for everything from drag racing to circle track to NASCAR.

What is the difference between Dana 70 and 80?

According to several sources, a Dana 80 can have a Gross Axle Weight Rating (GAWR) of up to 11,000 pounds. A Dana 70 can have a weight rating of up to 10,000 pounds, but 8,000 pounds is much more common.
