X-Factory X-6/60 one-piece top shaft

X Factory have released this new top shaft to fit their X-6 & 6 Squared, X-60 as well as the B4 & T4. The new shaft has been CNC machined from a single piece of hardened steel and offers several improvements such as being perfectly round with perfect teeth. Also the previously used AE top shaft often wore out quickly, but this new hardened steel shaft is much more durable.
