This slide rack is an RC-scale replacement part for the YD-4 series, supplied under Yokomo part number Y4-202R. The rack is manufactured from wear-resistant steel and functions as the sliding element in the front steering assembly.
Fitment is limited to the DP-YD4 family; the unit supports DP-YD4 and DP-YD4MR chassis. It is designed to replace the original slide rack without changing the steering linkage geometry when installed with compatible YD-4 components.
When fitting, confirm correct engagement at the servo linkage and tie-rod connections, verify smooth sliding motion, and check for binding through the full steering sweep. Replacing a worn rack restores consistent steering return and reduces play between the steering assembly and the servo output.
