The Yokomo Y2-303RBA is an aluminum rear brace made for the 2WD YD-2 drift chassis. It establishes a strong mounting point at the rear and includes a top plate shaped to accept a 30mm square cooling fan.
Fitting a separately purchased 30mm fan onto this brace lets builders add active cooling to a rear-mounted motor without changing the motor position or major chassis parts. The brace is supplied without a fan and is intended as an aftermarket upgrade to help control motor temperature and support rear-end tuning changes.
Installation aligns the brace with the existing rear mounting points on the YD-2 chassis and secures it using the corresponding factory hardware; no cutting or permanent modification of the chassis is required. As a structural and thermal support item, the Y2-303RBA helps with setup work and thermal management rather than altering gearing or drive layout.
As a simple aluminum upgrade for YD-2 owners, the Y2-303RBA supplies a durable rear mount with fan compatibility to improve localized motor cooling and support chassis setup during practice and events.
