Check out some of the other stuff on my eBay store for the XRT and X-Maxx!

Upgrade your XRT or X-Maxx with the Widemaxx kit (long suspension arms only) with these easy to install Mud Guards. Check out the video - uses existing fastener holes and zip ties for a very easy and secure installation. Made of TPU which has springiness and damping, making it the ideal material to act as a splash guard and arm protector.

Note. Does not fit the standard width X-Maxx. I have another part for that coming soon!

Depending on which wheels and tires you use, you may need to do a bit of trimming at the wheel end. This is normal and to be expected and is not an issue. The idea was to make the guard get as close to the wheel as possible, for as much protection as possible. If there is a little bit of rubbing, simply trim with scissors or an exacto knife. 

This is a 3D printed part printed on a top quality Bambu 3D printer!

If you have any issues, shoot me a message!

Thanks!
