The Kyosho UM564-82 spur gear delivers precise tooth geometry for RT5 and RB5 models. At 48 pitch and 82 teeth, it is suitable for replacements or upgrades where repeatable mesh and smooth power delivery are priorities for on-track performance.
Specifically matched to Kyosho RT5, RB5, and RB5 SP setups, the UM564-82 mounts easily in the stock gearbox and helps maintain steady pinion contact. Its robust profile reduces the likelihood of premature wear under normal racing and club use.
