9.0 ATRO Key Parts: Suspensions and Trailers
9.0 ATRO Key Parts: Suspensions and Trailers
The problem of rubber bushing walkout is solved because ATRO’s pin freely rotates to prevent the entire bushing from turning in the leaf spring eye and wallowing it out. Inbound flanged outer sleeve limits lateral travel. UB20500-OS is offered as an oversized option (+.060")
Resistant to the chemicals polyurethane maintains a longer product life than rubber competition. The ATRO design also enables easier installation due to the separation of the sleeve and the upper mount bases. This reduces the amount the engine needs to be raised. The lower mount also has a snap groove to locate spacer sleeve to simplify installation. Kit includes hardware.
