Are more 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.

“They’re good only to 400hp max,” says Tom at Tom’s Differentials. “Anything above that should use today’s beefed-up, redesigned, nodular-iron aftermarket cases. They’re good to 800 hp, if built properly.
What are splines on axle?
The spline of an axle is the teeth or peak that are machined on the end of the axle and mesh with the differential or spool inside the pumpkin of the rearend.
How many spline axles do I need?
Any car worthy of a 9.99 or better elapsed time should be equipped with 35-spline axles at least. Heavier cars, or those with an anticipated load of 9,000 lb-ft should have nothing less than 40 splines.
How do I choose the right axle?
Clearly, there are criteria that should be factored into the selection process of an axle, including the weight and type of vehicle in which it’s to be installed, the weight of the axle itself, the type of suspension being used, the location of the transfer case, what size tire will be fitted and what type of work the …

The majority of Mustangs come equipped with a limited-slip type differential called Traction-Lok from Ford. A limited slip differential maintains traction by “sensing” when one wheel is slipping, locking the wheels together and thereby redirecting greater torque to the non-slipping wheel.

What is the difference between 28 spline and 31 spline axles?
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 choose strange engineering for axle splines?
We can not stress enough the importance that Strange Engineering does all of its machine work on the axle splines prior to heat treatment. This allows for consistent heat treat depth, leading to a stronger axle.
