Product Overview
The Watson & Chalin 52000045.R01Z is an upper right-hand arm assembly for Watson & Chalin auxiliary lift-axle suspensions. It is the current replacement for discontinued part number 930356-20Z.
Installed in the upper right-hand position, this arm helps locate and control the lift axle as the suspension moves through its travel. Its side-specific design matches the right-hand mounting position of the original 930356-20Z arm, allowing customers to replace the discontinued component with the current Watson & Chalin/Hendrickson part number.
This product includes one upper right-hand arm assembly. For the corresponding left-hand arm, use 52000045.L01Z, which replaces 930356-10Z.
