FAZER On-Road O-Ring Set - Kyosho W5018B  [KY-W5018B]

FAZER Drift O-Ring Replacement Set

The Kyosho W5018B O-Ring Set is supplied as a spare kit for Kyosho FAZER on-road models, with particular usefulness for FAZER Drift configurations. Use these replacement seals during routine upkeep or whenever worn O-rings are identified on scale on-road drivetrains and related small assemblies.

Fitment depends on FAZER series parts layouts; inspect your model parts list before purchase to confirm compatibility. This kit is intended for maintenance and restoring original sealing performance rather than delivering a performance upgrade, and it replaces O-rings used in couplings, joints, and small rotating parts typical of on-road chassis assemblies.

Installation notes: detach the affected component, clean mating faces of old lubricant and debris, then install the replacement O-rings carefully to avoid twisting or nicking. A light assembly lubricant helps seat rings without overstretching. Reassemble and check for free rotation and proper seal contact before operating the model.

Practical tuning role: O-rings do not alter handling, but maintaining seals prevents lubricant loss and the ingress of grit, which preserves consistent drivetrain response and reduces wear on bearings and gears.
