Upper Control Arms | Tech Talk
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.
