Durable alumite rail for YD-4 slide rack systems

This RC-scale aluminium rail serves as a direct replacement for the slide-rail component in YD-4 slide rack assemblies fitted to the Y4-202LW. The alumite hard-coating helps reduce friction and resists surface wear so the slide action remains uniform through repeated sessions.

The part is made to work specifically with the Y4-202LW slide rack housing and is shown as compatible with DP-YD4 and DP-YD4MR chassis. It is intended as a maintenance replacement when original rails develop play or scoring marks.

Installation is a simple internal swap: remove the rack cover, fit the alumite-treated rail in place of the old one, check for free lateral movement, and refit the cover. Replacing worn rails helps keep tuning adjustments predictable by restoring consistent slide behavior.
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.

Which housings and chassis list this part as compatible?

This rail is designed for the Y4-202LW slide rack housing and is compatible with DP-YD4 and DP-YD4MR chassis models.

How should I inspect a worn rail before replacing?

Look for lateral play, surface scoring, or rough travel; noticeable binding or uneven motion indicates it is time to replace the rail.

Does the replacement affect setup tuning?

Restoring a smooth rail reduces setup variability and makes slide-related adjustments more repeatable, which simplifies fine tuning on track.
