This steering block set is produced for the YD-4 range and is supplied as one left and one right unit. It is intended for direct replacement on YD-4 platform touring cars during maintenance or repair.
The parts are compatible with DP-YD4 and DP-YD4MR chassis variants and match the steering geometry used by those platforms. Once mounted they form part of the front steering linkage and contribute to steering accuracy and wheel alignment control. Prior to installation, confirm linkage layout and ball stud placement to maintain correct toe settings.
Installation follows standard procedures: remove the wheel hubs and existing steering blocks, install the left and right units in the correct positions, then check for free steering movement before final tightening. After fitting, run a quick bench test to ensure symmetrical motion and absence of binding.
