Description

UMI’s rear control arm kit is a durable and reliable upgrade for your vehicle. This kit reduces suspension deflection for improved handling and reduced wheel hop. The lower control arms are reinforced with sway bar mounting holes for factory-style installation, and the included shim ensures the sway bar sits at the proper height. The upper fixed-length control arms feature heavy-duty mounting pads suitable for all rear end housings.
