We’ve been manufacturing 40 spline axle shafts in-house for a while now, but finally found the time to get them in our studio for a little photography love. For those new to our Ultimate 300M Axle Shafts, we do pride ourselves on making literally the best axle shaft in the market today. We follow the same heat treatment specifications found in 300M aerospace parts, namely careful combinations of snap tempering, cryogenic treatment, and double tempering to ensure every shaft is perfectly hardened inside and out. In addition, all Spidertrax 300M Ultimate axles are now vacuum quenched, ensuring surface contaminations from heat treatment are absolutely eliminated. The end result is an off-road axle shaft that meets or exceeds those parts found in aerospace.

TL;DR We make bad ass axle shafts, and they can be ordered online – http://www.spidertrax.com/Ultimate-300M-Floater-Shafts-40-Spline .
