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

Y4-641 One-Way Housing Overview

This one-way housing is built as an RC replacement to take standard YD-4 front parts. The unit contains a one-way mechanism tailored for front drivetrain use; note that its rotational locking differs from many drift packages, so verify direction before you secure it.

Designed to match DP-YD4 mounting points, the housing targets accurate fit and alignment. During assembly, align it with the differential output and confirm the one-way rotation is appropriate for your setup. Swapping components from drift kits will require a rotation and engagement check.

For ongoing maintenance, the housing influences how the front end engages and frees. Use matched bearings and drive cups to keep operation consistent, and periodically inspect the one-way surfaces and bearings to avoid premature wear.
