We just released our new Ultimate Housing yesterday, why stop there. Say hello to the all new Pro Series Stub Shaft, a fresh approach in building the strongest stub shaft on the planet. Designed specifically for our 40 splined Ultimate Unit Bearings, the Pro Series Stub Shaft is 40 splined, manufactured out of billet 300M, has a massive 1″ threaded locking fastener (no more snap rings), and still turns an amazing 50°. It’s the end all stub shaft, and with the insane speed and power of today’s Ultra4, the timing couldn’t be more perfect.

Learn more about the Pro Series Stub Shaft on our online store, http://www.spidertrax.com/Pro-Series-Stub-Shaft . As of this post, they are in stock and ready to ship same day.
