This RC-scale slide rack base is supplied as a direct replacement for parts in the YD-4 group. The component is manufactured from steel and provides the mounting foundation for the slide rack assembly where it interfaces with the chassis.
The base locates the slide rack and helps keep alignment under lateral load; replacing a bent or worn base will restore the intended rack geometry and reduce steering play that impairs precision.
Fitment aligns with YD-4 standard mounting points, so check seating during assembly and verify rack travel and centring before final tightening. No modifications are required for the supported chassis listed below.
