The V3R-0859 Delrin 59-tooth spur is specified as an aftermarket replacement for Kyosho V One RRR and V One RRR Evo 1/10 electric touring car drivetrains. Its Delrin construction offers a low-friction contact surface engineered to stabilise pinion to spur engagement under lap conditions while helping to limit gearbox drag.
Fitment uses conventional touring car procedures: remove the gear cover or chassis deck, swap the original spur for the Delrin 59T, then index the pinion mesh. Retain the original mounting hardware and manually rotate the drivetrain to verify smooth, consistent engagement before applying power. Precise shim and motor mount adjustments will tune noise and wear characteristics for competitive running.
As a tuning component aimed at track performance, this spur changes driveline feel and rolling friction rather than final ratio. Confirm the 59-tooth specification, bore tolerance and mounting interface against your existing unit to ensure accurate fitment and predictable performance on the setup bench.
