Zone Offroad Products expands its lineup of Adventure Series Upper Control Arms (UCA) to include the 2007-2016 Toyota Tundra 2/4WD. These new arms are a direct replacement for the factory upper arms and offer improved ball joint positioning for more wheel travel on leveled and lifted trucks. These new control arms dwarf the factory stamped steel units for improved performance and strength, with high quality ball joints and OE style rubber bushings for a smooth, quiet operation.
