Yokomo Y4-415S Steering Block for YD-4, left and right steering blocks for YD-4 chassis  [Y4-415S]

Steering block for YD-4

This is an RC-scale steering block designed for the YD-4 family, supplied as one left and one right piece. It serves as a direct replacement steering block for the YD-4 platform and is intended for use on hobby-grade touring car builds and repairs.

The part supports DP-YD4 and DP-YD4MR chassis layouts, matching the steering geometry of those platforms. When installed, it forms part of the front steering linkage and contributes to steering responsiveness and alignment stability. Check existing linkage orientation and ball stud positions when swapping this part to maintain correct toe and wheel alignment.

Installation is straightforward for those familiar with chassis maintenance: remove the wheel hubs and existing steering blocks, fit the left and right items in their respective positions, and verify free steering travel before final tightening. After installation, perform a quick on-bench steering check to ensure no binding and that both sides move symmetrically.
