Upper Link Shaft Details

This scale top shaft is made for the YZ-4 4WD off-road chassis and serves as the upper suspension link spindle. It locates the top of the suspension arm and transmits setup changes through the top link system.

The component is hard anodized aluminum to improve surface durability where link motion contacts the shaft and to provide consistent mounting for bearings or link hardware. Prioritised here is predictable linkage performance over decorative finishes.

For installation, carefully remove the original top shaft while maintaining correct bearing placement and thread length; check alignment with YZ-4 mounting points and ensure clearance against nearby parts before locking fasteners. Follow standard RC maintenance procedures when handling the assembly.

Compatibility

  • YZ-4
  • B-YZ4
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.

How does the Z4-303TA affect link alignment over time?

The hard anodized finish helps maintain a consistent contact surface, which can stabilise alignment as link bushes and bearings wear; routine inspection is still advised to detect play early.

Are there corrosion concerns with this shaft?

The anodized layer offers good protection against oxidation for aluminum parts in normal use, but rinse and dry the area after exposure to salt or chemical cleaners to prolong life.

Can I use the same link hardware from my stock YZ-4?

Yes, standard YZ-4 link hardware is generally compatible; verify that bearings seat properly and that recommended spacers are installed to maintain correct geometry.
