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. These shaft sets are also compatible with our Mk2 motor mount with integrated outrigger bearing.

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 end of the cap is also 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:

WITH PLAIN 8MM SHAFT

Comes with a plain 8mm shaft that allows fitment of standard 8mm bore spur gears, both Mod1 and Mod1.5. DON'T FORGET TO BUY AN 8MM BORE SPUR GEAR!

WITH CUSH COMPATIBLE DRIVE SHAFT

This is compatible with the original cush drive spur gear - no extra parts needed

There are two further options - these are 'SHAFT ONLY', and allow you to buy just the shaft, so you can change from one type to the other at a later date

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.
