Kyosho V One RRR Compatible 55T Delrin Spur Gear - V3R-0855 by 3Racing  [V3R-0855]

Delrin 55 Tooth Spur for V One Series

This is an RC replacement spur designed for the Kyosho V One RRR and V One RRR Evo platforms, listed as model V3R-0855. Delrin reduces friction at the mesh compared with conventional nylon, which helps produce smoother engagement under load while preserving the original gear ratio and tooth count.

Fitting the gear is straightforward for anyone used to spur swaps: remove the gearbox cover, inspect the spur hub and motor pinion alignment, slide the Delrin gear onto the original hub, and confirm mesh and side clearance before tightening. While installing, inspect mating faces and bearings for wear to maintain consistent driveline performance.

From a tuning perspective, a low-friction Delrin spur is a simple upgrade to lower drivetrain drag and improve throttle response on small electric cars. Pay close attention to gear mesh, pinion engagement, and any new noises after the swap. This item is for RC model use only.
