Question by: Kurt J on Nov 29, 2025, 3:38 PM

does this hub work with a 9 tooth SAE A spline shaft, or is that just the hub configuration itself?

Answer by: Customer Support on Dec 1, 2025, 1:11 PM

The 9 tooth SAE A spec describes the spline configuration on the hub, so yes, it's built to mate with a matching 9 tooth SAE A splined shaft. The spline details are 16/32 diametral pitch with a 30 degree pressure angle and a 5/8 inch outer diameter spline. As long as your shaft matches those specs, you're in good shape for a proper fit.

What's the OD on the spline itself? Just want to make sure it'll fit my setup.

Answer by: Customer Support on Jul 2, 2025, 7:54 AM

The outer diameter of the spline is 5/8 inch.
