HobbyPark Metal 7075 Aluminum Alloy 32 Pitch Pinion Gear Set 3.175mm Shaft Hole 17T 18T 19T 20T Motor Gears Kit for RC Car (4-Pack)

DO NOT BUY!!!!!! DAMAGED FROM FACTORY HIGHLY P.O.! UNEVEN CUT GROUND DOWN FACE MISSING SCREWS HORRIBLE IDEA TAKE YOUR MONEY ELSE WHERE !!!!!!!!! I only gave it 1 star because it had to have a rating if there was a trashcan emoji definitely woulda smashed that

they are so cheap that a plastic spur gear eat them up stayaway

Was supposed to be 4 piece set but only 3 in package. But they fit and work

Buy hardined steel

Love the quality of these pinion gears, also enjoy that each one has the lock dow. Screw for them. Using this on my 1/10th scale Traxxas rally fiesta that's been hopped up with the slipper clutch system as a 0.8 pitch and is now flying down the road at 68mph

I ordered the wrong gears

Had a metal spur gear in and ate them up. But reinstall plastic gear and there great.

I love the quality of the material and the speed they create. great for top speeds but what motor temps.

They were as described and work good. No sign of premature wear on my plastic spur gear. Gear to gear fitment is very smooth.
