|  C.I. - 4340 steel - Axial transmission outputs for Traxxas Maxx driveshafts
Crawler Innovations is proud to finally offer our 4340 steel - Axial transmission outputs for Traxxas Maxx driveshafts. This is a permanent fix to weak outputs, weak drive shafts, and heavy metal drive shafts. These outputs are cut from 4340 "Chrome Moly" steel. They are CNC machined to fit the Traxxas T / E Maxx drive shafts. The parts numbers are: Traxxas Heavy Duty input yokes #4928X Traxxas Heavy Duty drive shafts #4951X These are the axle drive shafts from Traxxas, not the smaller drive shafts for the transmission. The reason the front shaft is longer is to allow for clearance of larger spur gears in order to gear lower for increased torque. For brushless motors this is critical to ensure a smooth start up and no cogging. They are sold in a set. A set is one long front and one short rear. These are Made in the U.S.A. Vendor thread information is here: C.I. - 4340 steel - Axial transmission outputs for Traxxas Maxx driveshafts   Here is a set installed on my SCX-10 based 1.9 scale Toyota. I am using a 96 tooth spur gear and 15 tooth pinion on a Tekin 13.5 sensored brushless inrunner motor using a Mamba Max Pro on 4S. The truck is as smooth on start up as my brushed 2.2 comp trucks using Holmes Hobbies hand wound motors.  Yes, it's a giant 96T spur gear but the smooth crawlability even with a brushless motor is amazing.  Here you can see just how much clearance you have between the output shaft, spur gear and drive shaft yoke. You could actually go bigger if you can find a company that makes a bigger 48pitch spur gear.  This pictures shows that the drive shafts clear all link mounting and links.  Crawler Innovation is in a growth phase at the moment. A new web site is under construction and the current web site will be deleted. I am not adding new products to the current web site, so you need to email me directly if you want these or other products not listed on the current web site. My direct email is: novasark@crawlerinnovations.com As always, thank you so much to everyone for your support of me and Crawler Innovations products. Without good customers like you, none of this would be possible. Thank you, Eddie |

These look awesome. Are you using an adapter on the diff input side?

It is a proto type. I am working on an adapter for the pinion on the axle for the maxx shaft. It has both the correct pin hole and flat for the Traxxas T/E Maxx Yoke since Axial won't drill there axle pinion gears and there pinions are hardened steel which can be difficult to drill. Also, Crawler Innovations will not be making gears for the Axial transmission using these outputs. Sorry. Hot Racing and Robinson Racing both make after market gears of good quality for the Axial transmission. I'm just adding that in here because I already received several emails asking about it. | ||

If the proto type works out well, these will have everything you need to convert over in a "bolt on" package with no modifications. | |

 Thanks bro, that means a lot coming from you. And yes, I want the easy button when building crawlers so I am trying to think outside the box and create some nice complete package stuff. There is a lot more coming from Crawler Innovations this year. | |

It is soooooo good to see someone making these again. I have been using the old adapter that we used to be able to get from RC4WD. Glad to see you are working on those also |

Eddie, besides the benefit of the larger spur, what is the advantage of these over using steel outputs with MIP shafts? Not doubting, just playing a little Devil's advocate to get some more feedback and detail. Thanks! |
