JK Products 48P Plastic Pinion Gear (3.17mm Bore) (31T)
Installed in a Kyosho Javelin re re. 17.5T HW motor and ESC, Kyosho upgrade spur gear.

The good: This gear works as advertised. Just by rolling the buggy on a flat surface, I could tell that rolling resistance was greatly reduced. Tested under power, the car was noticeably quicker.

The bad: The gear is strangely noisy. It may be an imperial and not metric pitch.

It also is very thin and I am not sure how long it will last, or whether it will cause my spur gear to develop weird wear patterns.

The baffling: Why did JK make the grub screw imperial and not metric?

I have ran the 31t pinion for months in both 21.5 and 17.5 with a slipper eliminator on carpet for 2wd racing. I have zero issues and this pinion literally shaved off .2 seconds of my overall 12ish second lap times. It shows 0 wear and tear just looks dirty. No gear cover either. I will be ordering more in various sizes when I move to mod.

The set screw is not 1.5mm like it should be. None of my standard RC tools work with it.

These gears work great if you run on carpet or use a transmission gear cover...if you run in dirt ouside they may pick up small particles and chip the teeth.

Grate lite gear. If you need a set screw it is a 4-40 x 1/8"

These are great. They wear a bit faster than traditional steel pinions (especially on outdoor tracks)but it is worth it. Highly recommend.

JK Products 48P Plastic Pinion Gear (3.17mm Bore) (29T)
Very narrow. Teeth only make contact with 1/4 of the spur gear width. Shaft material very thin, lock screw stripped it out on just the second pack. Do not recommend for anything above maybe a 1/16 scale, if at all.

Will not fit on a Traxxas BL-2S motor shaft. This is very disappointing.

Super smooth, long lasting. Run with. A 17.5 and 13.5 SCT on carpet with zero issues. Not recommended for harsh dirt conditions. Smooth clay maybe fine.

JK Products 48P Plastic Pinion Gear (3.17mm Bore) (26T)
These are great pinion gears. They come with a smaller set screw than normal for lighter weight. You should add a film of grease on the shaft so it doesn’t get stuck on, tolerances are tight but that’s great.

Garbage! I’ve used 2 different ones and both got stuck on the end of the rotor. The 2nd one almost ruined my rotor trying to get it off! Do not buy!

It is a very good pinion because it prevents wear and reduces noise
