Does anybody make a plastic spur for the MBX5T (46T).

I doubt it. Why would you want a plastic spur? I don't think it would last long before stripping out.

There is no direct-fit plastic spur for the Mugen diff. I use a Kyosho center diff with the Kyosho 46T plastic spur in my 5T. You need the Kyosho center diff braces and top plate too, but they fit perfectly in the existing holes in your chassis.
I have never stripped a plastic (nylon actually) spur. They are quite durable. They do wear out some. I replace it once each race season.

Why would you want a plastic spur?

Reduced rotating mass.

My 5T is electric. A metal spur will eat my pinion in a race or two.

Happywing, which model Kyosho diff did you use?

IF148.
It's readily available. You can get it or even a complete Kyosho diff here:

Should be on eBay too, if you like to go that route.
