Jeep Grand Cherokee Lifts Require Upper Control Arm Upgrades

The Jeep Grand Cherokee 2nd, 3rd, and 4th generation are respectively known as the Jeep Grand Cherokee WJ (1999-2004), Jeep Grand Cherokee WK (2005-2010), and Jeep Grand Cherokee WK2 (2011-present).

JBA Offroad manufacturers upper control arms (also known as UCAs or upper a-arms) for the Jeep Grand Cherokee. With the right modifications, these Jeep Grand Cherokee models are exceptionally capable off-road vehicles.

All Jeep Grand Cherokee models since 1999 have independent front suspension and require replacement of factory upper control arms when lifted. If factory UCAs are not replaced, your Jeep Grand Cherokee alignment and clearances will be both incorrect and unsafe.

When Jeep Grand Cherokees 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 Jeep Grand Cherokee, 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 Jeep Grand Cherokees, and driven all over the world. JBA UCAs work with Jeep Grand Cherokee lift kits up to 4 inches above factory ride height.
