Splines are parallel grooves on the side of a shaft that engage with matching grooves in a socket. They allow power to be transmitted between two rotating elements. Splines are used on axles to allow them to be removed and replaced.

The larger the spline count, the larger the axle. Strength depends on the type of metal. All things being the same, the bigger, the better.

This is just a random pic I pulled off the net showing the difference between a 28 spline axle vs 30 spline axle. How bout those c-clips?

Keep in mind that you have to change the carrier if you change axle splines.
