Product Overview
The Watson & Chalin 930356-10Z is a left-hand upper arm assembly designed for heavy-duty trailer air-ride suspension systems. It’s a cast aluminum arm with poly bushings, engineered to deliver durability, reduced weight and improved articulation.
This arm is typically used on Watson & Chalin lift, tag or axle-beam suspensions where OEM replacement quality and fitment are required.
Ideal for drop-axle, lift-axle or tag configurations in trailers where the upper arm serves as a key pivot point for suspension movement.
