This complete kit replaces your weak, factory stamped lower control arms and panhard bar with our heavy duty tubular setup. These direct bolt-on replacements minimize wheel hop, improve cornering while lowering ET's and helping track consistency. The panhard bar greatly increases rear stability, controls side movement and body flex while the lower control arms help to reduce unwanted wheel hop. Both items are constructed of Seamless DOM mild steel tubing, stronger and less flex then Aluminum made versions on the market. Control arms and panhard bar are both completely CNC machined and fully TIG welded featuring Energy Suspension polyurethane bushings, zinc plated steel sleeves and "on car" grease-able grease fittings.
