Kyosho V One RRR Race-Tuned Delrin 56T Spur Gear - V3R-0856/V2 by 3Racing  [V3R-0856/V2]

Race-focused 56T Delrin spur for V One RRR

Model V3R-0856/V2 is a 56-tooth Delrin spur produced as a drop-in replacement for the Kyosho V One RRR gearbox. The polymer tooth surface reduces mesh friction to aid consistent spool-up and repeatable lap-to-lap drivetrain behaviour.

Material and role: Delrin lowers surface friction at tooth contact, reducing micro-loading on the motor and smoothing engagement under rapid throttle changes. Use this part as a tuning tool when refining backlash, gear mesh, and pinion choices for competitive setups.

Installation notes: Remove the radio tray or access cover, extract the factory spur using the original screws, fit the Delrin 56T in the same orientation, and re-secure with the vehicle hardware. Precisely set mesh to avoid binding and verify free rotation by hand before track sessions.

Tuning considerations: Expect changes in how different pinion sizes and motor profiles react; re-evaluate pinion choice and check for runout after installation. Monitor tooth wear through initial test runs and use the change as part of iterative setup tuning focused on drivetrain consistency.
