A suspension upgrade system designed for Jeep Grand Cherokees replaces the factory control arms with longer ones. This modification is intended to improve off-road performance, primarily by allowing for greater suspension articulation and travel. As an example, installing such a system can increase a vehicle’s ability to navigate uneven terrain.
The implementation of extended control arms offers several advantages, including improved handling at higher speeds when combined with a lifted suspension. The altered geometry can optimize the vehicle’s roll center, leading to enhanced stability. Historically, these systems were developed to address limitations found in the stock suspension designs of Jeeps used in demanding off-road environments.
