About this part
Robinson Racing Extra Hard Blackened Steel 32 Pitch Pinion gears are built to last. Made from high carbon steel and then heat treated to increase the hardness of the surface even more. High carbon steel is naturally higher in lubricity and lower in adhesion than milder grades of steel making these gears ideal for use with metal spur gears. Can be run on motors using a 5mm motor shaft including Traxxas, Associated, and HPI models or for any heavy duty application. Standard 1/8 shaft motors will require a 5mm to 1/8 inch Reducer Sleeve (RRP1200). These pinions are available in a variety of tooth count options. Choose one from the pull down menu above.
Features:
- Extra hard high carbon construction
- For use with the Robinson Racing GEN3 steel slipper units
- 5mm Bore Fits 5mm motor shaft
- Available in multiple tooth count options, use the pull down menu above to pick the size you need
NOTE:
- RRP1200 5 m/m to 1/8 inch Reducer Sleeve required for 1/8 inch shaft motors.
- 32 pitch and .8 module gears can be used together with no adverse affects such as increased noise or increased wear. The difference is that .8 module gears have a slightly larger outside diameter per tooth, roughly .00027 of an inch.

Good quality fast shipping not big enough for motor upgrade prob need 20t
had a tooth break off after a few months of abuse, pinion looked great aside from that not sure what happened.
I use Robinson on all my trucks, they are great. Never had a problem.
This pinion gear is not a match for the spur gear I ordered for my Tekno EB 48 2.2 very disappointed
Four verified-owner reviews cover three tooth-count variants (11T, 12T and 17T). Reviewers' experiences differ. One 12T owner reported no problems and said they use the brand on all their trucks. One 17T owner reported a broken tooth after several months of use, with the rest of the pinion still in good condition. Another 17T owner rated the product 1/5, saying it did not match the spur gear they ordered for a Tekno EB 48 2.2. An 11T owner rated it 5/5, praising quality and fast shipping, but said it was too small for a motor upgrade and would likely need a 20T. Overall the reviews point to mixed fit and durability for the 17T variant, with limited data for the others.
- + Good quality
- + Fast shipping
- + No problems reported over long use (12T)
- − Tooth broke after a few months (17T)
- − Did not match spur gear for Tekno EB 48 2.2 (17T)
- − 11T too small for motor upgrade
