Description

UMI’s boxed rear lower control arms are a durable upgrade for your vehicle. These arms are suitable for various driving conditions and help minimize suspension deflection for improved handling and reduced wheel hop. The sway bar mounting holes are reinforced for added strength, and the included shim allows for factory style sway bar mounting at the correct height. UMI’s control arms are precision CNC machined and come with high quality greaseable polyurethane bushings. Installation is straightforward and can be completed in about an hour with basic hand tools.
