What is the difference between a 31 spline and a 28 spline?
The difference between a 31 spline and a 28 spline refers to the number of splines, or teeth, on the end of a shaft or axle. This specification is crucial in various industries, from automotive to industrial equipment, as it determines the compatibility and strength of the connection between components.
What is a Spline?
A spline is a series of grooves or teeth cut into the end of a shaft or axle. These splines allow the shaft to transmit torque and power to another component, such as a gear or differential. The number of splines, or teeth, on the shaft determines the specific application and compatibility of the component.
31 Spline vs. 28 Spline
The primary difference between a 31 spline and a 28 spline is the number of teeth on the shaft. A 31 spline shaft has 31 teeth, while a 28 spline shaft has 28 teeth. This seemingly small difference can have a significant impact on the strength and durability of the connection.
- 31 Spline: The 31 spline design is generally considered stronger and more robust than the 28 spline. The additional teeth provide more surface area for the transmission of torque, making the 31 spline better suited for high-performance or heavy-duty applications.
- 28 Spline: The 28 spline design is often used in more standard or lighter-duty applications, where the reduced number of teeth is sufficient to transmit the required torque. This design may be more cost-effective and easier to manufacture in some cases.
It's important to note that the specific application and requirements of the equipment or vehicle will determine which spline design is most appropriate. Consulting with the manufacturer or a qualified professional is recommended to ensure the correct spline size is used for a particular application.
How much power can 30-spline axles handle?
"This will give you a figure that represents the maximum amount of torque transmitted to both axles if you launched at your engine's torque peak and dead-hooked out of the hole. A 30-spline axle is rated at 6,200 lb-ft, a 31-spline at 7,000, a 33-spline at 8,200, a 35-spline at 9,600, and a 40-spline at 12,000.
Do splines add strength?
Synopsis: Splines are a well-known technique for adding strength to miter joints, but there are times when a visible spline spoils the look of a box; for example, when you have carefully matched grain wrapped around all four sides.
Are all Ford 8.8-31 spline?
A common weak spot in the Ford 8.8 rear axle is its 28-spline axleshafts (1.18 inches in diameter). Stronger 31-spline axles are available from the aftermarket, but they require a new carrier and side gears to be installed, negating any cost-savings.
How do you know what size spline to use?
The spline size needed depends on the size of the channel in your screen frame, as well as what type of screen you use. The best way to ensure you have the correct size spline is to measure the diameter of the existing spline in the frame and then purchase the same size.
What is the difference between 28 spline and 31 spline?
The obvious differences in 28 and 31 spline axles will be the number of splines! When you count the number of teeth (splines) on each axle, you can find out which option you have. 31 Spline Axles also tend to be larger in diameter to accommodate the increased amount of splines.
Why is the Ford 8.8 rear end so popular?
And Broncos especially the four-wheel drive models and those with bigger engines. But not always because mine's a 300. And it's got an 8.8.
Are more splines stronger?
Generally, more splines means a larger-diameter, stronger shaft (the 14-bolt 30-spline is an exception).
What is the diameter of a 28 spline axle?

What is the diameter of a 31 spline?
31 spline shafts have a major diameter of 1.333" at the splines.
How do you know if a spline is 28 or 31?
The obvious differences in 28 and 31 spline axles will be the number of splines! When you count the number of teeth (splines) on each axle, you can find out which option you have. 31 Spline Axles also tend to be larger in diameter to accommodate the increased amount of splines.
