These are adjustable rear upper control arms for the 3rd Gen Tundra, usable on lifted or stock trucks up to 4 inches of lift. Their job is to let you set the rear pinion angle correctly after adding a lift while also adding strength over the stock arms. Dobinsons also says they suit long-travel rear suspension setups.
They are made from HSLA steel, 30mm in diameter with a 5mm (0.2 inch) wall, zinc plated and powder coated black. The adjusters and rod are oversized and have a double-nut locking feature, and the arms can be adjusted on the vehicle: the left-hand thread side has a silver nut and the right-hand thread side has a gold nut.
Fitment
3rd Gen Toyota Tundra, rear upper position, for lifts up to 4 inches. The vendor notes the arms do not include a headlight adjustment bracket.
What's included
Both upper arms and four rubber bushings, for owners who prefer not to run the polyurethane bushings. The rubber bushings must be pressed into the arms.
Questions before you order?
Fitment questions are easier to settle before the box ships. Call or text Carl & Anton at (920) 249-7744 or use the chat — real humans in Sheboygan, Wisconsin, not a call center.
