AM Arrowmax "SL" Molded Composite 48P Pinion Gear (3.17mm Bore) (34T)
These are an excellent alternative to the colored thin plastic slot car pinions. I found them extremely lightweight, spin true, and very quiet in 1/10 off-road buggy. Most importantly they are all black in color. The only reason I did not give five stars, the set screw is very small and in small piece of alum. You have to be very careful not to over tighten and break/strip.

P.S The one negative review, these are for racing and not designed for crawlers. Use in the right application and these are fantastic.

It’s a pinion but it does sound different than a metal pinion. I am using it for a stock spec buggy. It works as it should it just sounds louder. I’m hoping it pays off at the track. I will have an aluminum pinion with me just in case.

AM Arrowmax "SL" Molded Composite 48P Pinion Gear (3.17mm Bore) (36T)
Melted on my bench while testing it out. On a crawler. Plastic spur gear. Super thin and trash. Don’t buy
