Lexus GX470 Lifts Require Upper Control Arm Upgrades
JBA Offroad manufacturers upper control arms (also known as UCAs or upper a-arms) for the Lexus GX470 beginning with the 2010 model year. With the right modifications, Lexus GX470 models are wonderfully capable off-road vehicles.
All Lexus GX470 models have independent front suspension and require replacement of factory upper control arms when lifted. If factory UCAs are not replaced, your Lexus GX470 alignment and clearances will be both incorrect and unsafe.
When Lexus GX470s are lifted, caster is lost from the front-end alignment. 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 Lexus GX470, 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 the vehicles with independent front suspension to be safely lifted. Today, JBA upper control arms are installed on thousands of vehicles, including lifted Lexus GX470s, and driven all over the world. JBA UCAs work with Lexus GX470 lift kits up to 4 inches above factory ride height.
