Reliable 3Racing pinion for tuned gear ratios

The 3Racing 64 Pitch Pinion Gear 21T provides a compact, robust option for RC drivers seeking predictable drivetrain behaviour. Its 7075 aluminium construction with a hard coat helps resist wear while keeping the rotating mass low.

What to expect from the 21T

The 64 pitch cut gives consistent tooth contact and smooth power transfer, making the 3Racing 21T a good match for high speed or precision touring car setups where stability matters.

Installation and care

Set the mesh carefully and tighten the fixing screw to secure the pinion. Regular inspection after heavy running will catch any misalignment early and protect both pinion and spur from damage.

Use a thin paint transfer technique or feel for a light, even backlash across teeth while rotating to ensure correct mesh setting before running at speed.
The 3Racing 21T is versatile and works well on both on-road and off-road 1/10 scale rigs that accept 64 pitch gears; choose final drive ratios to suit the terrain.
Light lubrication on the spur and periodic checks are recommended; avoid heavy greases that can attract dirt and increase wear on aluminium gears.
