Take care of a worn upper arm and its ball joint in one step with the SKP SK620063 front right upper control arm with ball joint, which comes with the ball joint already installed. It fits many vehicles, among them the 2003-2023 Toyota 4Runner, 2007-2014 Toyota FJ Cruiser and 2010-2023 Lexus GX460, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list.
The upper control arm connects the steering knuckle to the vehicle's frame and lets the wheel travel up and down. The ball joint is the pivot that allows the knuckle to steer and move with the suspension. If worn original parts are behind a loose or unsettled front end, this unit is designed to help restore proper handling and control.
This part is for the front right upper position and is sold individually. Replacing both upper arms together is recommended for balanced handling. Have the wheel alignment checked after installation.
