Front One-Way Housing for DP-YD4 - Yokomo Y4-641  [Y4-641]

Yokomo Y4-641 Front One-Way Housing Notes

This front one-way housing is an RC replacement part made to accept YD-4 standard front components. It encloses a one-way mechanism intended for front drivetrains, and because its rotation differs from many drift-specific assemblies you should confirm orientation before final fitting.

The unit is produced to match DP-YD4 geometry and fixing points so compatibility is targeted. When assembling, align it with the diff output and check that the one-way rotates as required for your setup. Parts transferred from drift kits must be rechecked for correct rotation and engagement.

In tuning scenarios, this housing affects how the front end engages under drive. Fit it when you want the front to freewheel in one direction and lock in the other, and use compatible bearings and drive cups to maintain consistent behaviour. Inspect the one-way faces and bearings periodically to maintain dependable engagement.
