Kyosho V One RRR 56T Low-Drag Delrin Spur Gear for Tuning - V3R-0856/V2 by 3Racing  [V3R-0856/V2]

56-tooth Delrin spur for smoother mesh

V3R-0856/V2 is a 56T Delrin spur supplied as a replacement option for Kyosho V One RRR transmissions. The polymer tooth surface is chosen to lower friction within the gearbox and to support finer gearbox setup for on-road driving.

Material and role: Delrin reduces contact friction at the tooth interface which can translate to a smoother feel and altered motor load under acceleration. Use this component as a tuning element when adjusting backlash and mesh clearances.

Installation notes: To fit, remove the V One RRR radio tray or access cover, remove the existing spur with the vehicle's original screws, install the Delrin 56T in the same orientation, and re-secure using the factory hardware. Check and set the mesh carefully, then confirm the gear runs freely by hand before applying power.

Tuning considerations: A Delrin spur affects how pinion size and motor selection interact. After fitting, recheck mesh, watch for runout, and monitor the spur for initial wear during shakedown runs while refining setup choices.
