HENS-21099
This is a thick bushing tube spacer (also called a wear pad) used on heavy-duty trailer air-ride suspensions. It installs between the tri-functional bushing and the suspension hanger to maintain proper axle alignment and prevent metal-to-metal contact. Over time, these spacers can wear, crack, or compress, leading to looseness and uneven tire wear; they are typically replaced in sets of four per axle whenever the bushings are serviced.
Requires 4 pieces per axle. Recessed side of pad must face the bushing.
