Adventure Series upper control arms dwarf the factory arms they directly replace. Made from cast ductile iron with CNC-machined ball joint and bushing mounts, these arms one-up factory components by providing a significantly increased range of travel and come equipped with stock-style rubber mount bushings to provide a smooth, quiet ride.
