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.
Are more axle splines better?
Higher spline counts gives the axle more surface to transfer the load of the torque from the differential. There is also the side advantage that an axle with more splines will also be physically bigger. At least in most modern axles that use similarly sized spline teeth.
How much power will 31 spline axles hold?
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.

What is spline in gear?
Splines are ridges or teeth on a drive shaft that mesh with grooves in a mating piece and transfer torque to it, maintaining the angular correspondence between them. For instance, a gear mounted on a shaft might use a male spline on the shaft that matches the female spline on the gear.

How do I know if I have a 9-inch diff?
Many enthusiasts will tell you to look for the two dimples in the rear cover to determine if the unit is a 9-inch, but this is not always true. Ford also had an 8-inch third-member rear end that had a dimpled cover. The best test of a 9-inch carrier is to try removing the two lower carrier case bolts.
What are the alloy axles made from?
The Alloy axles are made from a high-forged alloy steel, are CNC-machined, and there is just a two-day turn around time on custom axle ordering. The Strange proprietary Alloy material is induction hardened, which means the metal is heated by an electromagnet and then rapidly cooled (quenching).
What is the turnaround time for strange alloy steel axles?
With an approximate 2-day turnaround time, each Strange forged alloy steel custom axle is manufactured to your exact specifications. To provide greater flexibility, Strange alloy axles are CNC precision machined from premium forged alloy steel and are induction hardened to resist bending loads.
What is the bearing area of a strange axle?
Strange axles are manufactured with a large bearing area diameter (1.563-inch) for additional strength. To minimize stress concentration, the Strange axle shoulder is designed with an extra large radius and utilizes a adaptive ring.
