Spur gear shaft upgrade – for Traxxas Xmaxx & XRT

Upgrade your drive train with this true 8mm Titanium shaft set up. It’s 8mm thick right up to the front bearing, NOT a 6mm shaft with an 8mm end section.

This set up solves the poorly supported 6mm shaft spur gear setup.

Beefing the shaft up to 8mm in grade 5 Titanium adds a huge chunk of strength and stiffness. 

The aluminium spur shaft cap then has a trick up it’s sleeve. The end of the cap is extended to carry a much bigger bearing and moves the bearing 9mm outwards, greatly shortening the shaft overhang, further strengthening and stiffening the setup.

Greatly reduces the chance for spur gears to be damaged and stripped from shaft flex.

The kit is offered in 2 options, one is compatible with the original cush drive spur gear, the other has a plain 8mm shaft that allows fitment of standard 8mm bore spur gears, both Mod1 and Mod1.5.

NOW FITS WITH TRAXXAS ‘OVERDRIVE’ TRANSMISSION SET (as fitted to the very latest models)

DON’T FORGET TO BUY A SPUR GEAR!

***When fitting the cush drive spur, the cush must be assembled facing the other way to the stock setup.***

***for use with 8mm bore spur gears only (Available on this site!)***

***Will not work with belt setups***

Gearing recommendations: We are always being asked about gearing!?Everyone has their own preferences, and different experienced people will tell you different things. In our test truck, we have a Castle 2028 1100kv. I run 37/50 Mod1 gears (our own gears, obviously!) This gives a good balance between high speed, drivability, motor heat and amp draw for MY driving style and locations. For an 800kv motor, the same top speed would require perhaps 35/47 gearing, or gears to give the same ratio

Modifying your RC from stock condition can result in unexpected results. Operation of modified models must take this into account. Always follow the original manufacturers instructions. Whilst we build our parts to the highest standards we are able, like all rc parts, our parts cannot be guaranteed for performance, strength and durability in every situation or configuration. Do not use your RC in public areas. Do not use your RC where unexpected results could cause injury or damage to property. High Speed RC’s require GREAT CARE and a responsible attitude to use safely.
