The Yokomo BM-4828A hard steel pinion is aimed at modellers who prefer durable parts that stand up to frequent use. With its 48-pitch, 28-tooth profile, this pinion gives consistent engagement and reliable torque delivery across different RC car platforms. The hardened steel build reduces wear and maintains gear geometry over many runs. Use it as a replacement or to improve drivetrain longevity without dramatic changes to gear ratios.
