2pcs Metal Steel Diff Main Gear 38T Motor Pinion Gear 17T For RC 1/18 WLtoys A959 A949 A969 A979 RC Car Electric Buggy Vortex Hop-up Parts (Silver)

I've heard many people having trouble with other gears fitting...this was came in 1.5 days and FIT 100% perfect to a 'T'.Great product, strong, cut gear!! Perfect fit even with the original primary gear! I feel the car is even faster now for some reason. Maybe not slipping any longer! Great seller!

Ordered due to Amazon saying it was for Dromida sc 4:18. Won't fit in shaft.

Gd on my 1st order

Shaft doesn't fit all the way but gear looks and feels solid .

Gears look like they’re good quality but they do NOT fit the a959b in stock configuration. The small gear does not fit on the motor shaft because the hole is too small, and the gears themselves (if they did fit on motor) are too small and do not mesh together.If you’re looking for metal replacements for your stock A959b this is not your gear set. I’m returning the gears and buying different ones.

After buying 4 different metel gears that were all wrong size I just did a little modify on the motor mount now it's adjustable I can run different set-up

It's didn't fit on anything

I ordered this because I have a motor with a 2mm shaft and the pictures indicated that the pinion gear would have a 2mm bore. The one I received this is clearly 2.3mm.This will not fit my motor with a 2mm shaft because it is not the same item that was described.
