The Yokomo B10-630OA aluminum outer drive pulley is a precision machined upgrade for BD10 builds. Its 20-tooth profile cuts down on belt stress while the hard coating lowers friction for smoother running and longer component life.
This lightweight yet tough pulley fits a range of Yokomo platforms, including MRTC-BD10FF, MSR-BDFWD, and MSR-010 series cars. Installers will find it a straightforward swap when refining gear layouts for racing or club use.
