This kit replaces your factory lower control arms and panhard bar with heavy duty tubular versions. These bolt-on replacements minimize wheel hop, improve cornering, and help with track consistency. The panhard bar increases rear stability and controls side movement, while the control arms reduce wheel hop. Both are made of Seamless DOM mild steel tubing for added strength over aluminum versions. They are CNC machined and TIG welded with polyurethane bushings, zinc plated steel sleeves, and grease fittings for easy maintenance. Installation is quick and easy, taking approximately 30 minutes using OEM hardware in factory mounting points.
