Toyota 4Runner Upper Control Arms
Toyota 4Runner Lifts Require Upper Control Arm Upgrades
JBA Offroad manufacturers upper control arms (also known as UCAs or upper a-arms) for the Toyota 4Runner beginning with the 2003 model year. With the right modifications, Toyota 4Runner models are wonderfully capable off-road vehicles.
All Toyota 4Runner models have independent front suspension and require the replacement of factory upper control arms when lifted. If factory UCAs are not replaced, your Toyota 4Runner alignment and clearances will be both incorrect and unsafe.
When Toyota 4Runners are lifted, the caster is lost from the front-end alignment. The caster is critical for stability over 45 miles per hour and returns the steering wheel to center after going around a corner. Additionally, factory upper control arms often rub on the front springs at certain articulations. If factory a-arms are not replaced when lifting a Toyota 4Runner, expensive and dangerous damage is likely.
JBA led the industry back in 2004 with the development of the first aftermarket upper control arms, which enabled vehicles with independent front suspension to be safely lifted. Today, JBA upper control arms are installed on thousands of vehicles, including lifted Toyota 4Runners, and driven all over the world. JBA UCAs work with Toyota 4Runner lift kits up to 4 inches above factory ride height.
