DP-YD4 Front One-Way Housing Details

This front one-way housing is a precision RC replacement that accepts YD-4 standard front components. It contains a one-way mechanism intended for front drivetrain layouts, and its freewheel/lock direction differs from drift-style packages, so confirm orientation prior to fitting.

Fit and compatibility are focused: the housing is manufactured to match DP-YD4 geometry and mounting points. During installation, check alignment with the differential output and ensure the one-way rotates in the required direction for your configuration. If transferring parts from drift sets, re-check rotation and engagement.

When tuning, this housing affects front-end engagement behavior. Use it when you need the front assembly to freewheel one way and lock the other, and pair it with matching bearings and drive cups for reliable operation. Inspect the one-way surfaces and bearings regularly to prevent wear-related issues.

Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Is this housing a direct fit for DP-YD4 assemblies?

Yes. It is produced to the DP-YD4 mounting pattern and accepts YD-4 front parts; still confirm screw lengths and clearances during mock assembly.

How should I orient the one-way during installation?

Orient the unit so the locked direction matches your desired front-drive behavior. The freewheel direction here is not the same as many drift-focused units, so do a rotation check before final tightening.

What post-fit checks are recommended?

After fitting, verify bearing alignment, confirm smooth engagement of the one-way, and re-torque screws after an initial run-in period to catch any settling.
