Front One-Way Unit for DP-YD4 Explained

This front one-way housing serves as an RC-scale replacement designed to accept standard YD-4 front components. It contains a one-way mechanism intended specifically for front drivetrain arrangements, and its rotation behavior is not the same as drift-oriented kits, so double-check orientation pre-install.

The housing is produced to align with DP-YD4 geometry and mounting bosses, providing focused fit and compatibility. During assembly, verify differential output alignment and ensure the one-way's rotation matches the front-drive needs of your build. If you transplant parts from drift packages, confirm engagement direction again.

When tuning, this housing alters front-end engagement characteristics. Install it when you need the front assembly to freewheel in one direction and lock in the other, and pair it with correct bearings and drive cups for steady operation. Regular inspection of one-way surfaces and bearings will extend service life.

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.

Can this housing change front-end handling?

Yes. Swapping to this one-way housing can alter when and how the front engages; use it alongside matched drivetrain parts to tune handling predictably.

Is bearing replacement recommended when fitting?

Replacing worn bearings during installation is a good practice to ensure smooth rotation and correct one-way function, especially on performance setups.

Any tips for reducing engagement chatter?

Use clean, appropriate lubrication on one-way contact surfaces and ensure bearings are free of play; correct preload and alignment will reduce chatter.
