YD-4 Steering Block Replacement for DP-YD4/DP-YD4MR - Yokomo Y4-415S  [Y4-415S]

YD-4 Front Steering Block Details

This is an RC steering block set made for the YD-4 family, supplied as one left and one right piece. It functions as a direct replacement for the YD-4 platform and is intended for use in hobby-grade touring car repair and maintenance.

The component supports DP-YD4 and DP-YD4MR chassis layouts and maintains the intended steering geometry for those platforms. Once fitted, it becomes part of the front steering linkage and helps preserve steering responsiveness and alignment stability. Confirm existing linkage orientation and ball stud positions when swapping parts to keep toe and wheel alignment correct.

Fitting is straightforward for anyone familiar with chassis work: remove the wheel hubs and the current steering blocks, install the left and right items in their proper positions, then confirm free steering travel before final tightening. After installation perform an on-bench steering check to ensure there is no binding and that both sides move evenly.
