Precision Tuning with Hobbywing 17T Steel Pinion

The Hobbywing 17T 5mm 32P Steel Pinion Gear 86040000 is a rugged replacement gear made to help you fine tune drivetrain ratios on your RC vehicle. Built from hardened steel, it resists wear from demanding use while letting hobbyists tweak acceleration and top speed for different driving styles.

Where to Fit This Pinion

This pinion suits 1/8 scale monster trucks like the E-MAXX, E-REVO and SUMMIT, and also fits many 1/10 scale rigs such as the SLASH 4x4. Swapping in the Hobbywing 17T alters the gear ratio so you can prioritise torque or top speed depending on terrain and load. Lower tooth counts give stronger acceleration and pulling power while higher tooth counts favour higher top speed.

Build Specs and Materials

The gear has a 5mm bore and a 0.8mm modulus, machined from 40CR steel for consistent meshing and long service life. These dimensions and material make it a dependable option for racers and weekend bashers who need repeatable performance.

Can I use this pinion on models outside the listed brands?

Yes, the pinion will work with many 1/8 and 1/10 scale vehicles as long as the bore and 32P pitch match your existing gear setup. Always check gear mesh and clearance before running.

How does changing this pinion affect performance?

Switching tooth counts adjusts the overall gear ratio. Fewer teeth increase torque and acceleration, while more teeth raise theoretical top speed but reduce low end pull.

What maintenance helps this pinion last longer?

Keep the gear free of debris, verify proper mesh, and inspect for wear after heavy runs. Light lubrication of mating gears can reduce friction and extend life.
