Upgrade the upper control arms on your GM HD truck for improved reliability and travel. Adventure Series upper control arms dwarf the factory arms and are made of fully-welded, 1/8" steel plate with CNC-machined ball joint and bushing mounts. These arms one-up their factory components and work in conjunction with stock-style rubber mount bushings to provide a quiet ride.
