Refine your setup with the 3RACING 48 Pitch Spur Gear 89T

The 3RACING 48 Pitch Spur Gear 89T provides straightforward gearing control for clubs and weekend racers. Its 48 pitch profile supports consistent meshing and sensible wear characteristics for varied terrain.

Why this 89T spur matter

Designed to suit a variety of 1/10 scale formats, the 89T spur lets you move gearing toward more usable torque for loose surfaces or open areas where throttle control matters. It is a practical choice when adjusting final drive ratios.

Where to use it

Club racing: Tune final drive to suit tight circuits or faster layouts.
Loose surfaces: Gain better traction by favouring lower gearing.
Everyday tuning: Simple, reliable gear for balanced running in hobby cars.

Can I use this spur on crawler conversions?

While sized for 1/10 scale sport and touring gearboxes, some light crawler builds can accept it if their pinion and shaft spacing match 48 pitch standards; check measurements first.

Should I change pinion size when using this spur?

Yes, altering pinion teeth is the usual way to shift final drive; smaller pinion increases torque while larger pinion raises top speed, so pick based on your driving surface.

How often should I inspect the gear?

Check the spur for chipped teeth or excessive wear after heavy sessions, and verify mesh and set screws after the first few runs to avoid slippage.
