3Racing F109-10 98T Spur Gear Precision Upgrade  [F109-10]

Precision Spur Gear Upgrade for F109 by 3Racing

The 3Racing F109-10 98T Spur Gear is a machined replacement built to sharpen drivetrain response on F109 chassis. Its 98 tooth profile helps hobbyists dial in gear ratios for tighter acceleration or refined top speed, while the robust construction supports repeated track sessions and steady power transfer.

Benefits of the 98T Configuration

Designed specifically for the F109 series, this spur provides consistent meshing and predictable behaviour under load. The 98T option gives finer steps between pinion choices so you can balance torque and velocity, and the durable material resists wear during aggressive runs.

Fitment and Simple Installation

Drop-in fitment to the 3Racing F109 chassis keeps installation straightforward using standard hardware. Whether replacing a worn stock gear or testing new ratios, the 98T spur installs cleanly and reduces drivetrain backlash for smoother operation.
