The Yokomo RD-415BA Bearing Adapter is built to sharpen traction and reduce rear shaft play on competition cars. By lengthening the universal shaft section it helps the axle run truer, while the included 1050 bearing partners with the aluminum rear hub carrier for reliable support on track.
This adapter works across many Yokomo RD, SD and MD chassis options, offering a practical upgrade path for tuners wanting better rear traction and predictable handling.
