Spohn Performance sway bars are the single biggest handling improvement you can make. Dramatically reduces body roll and increases cornering capability. Don't skimp on the foundation of your suspension! Eliminates body roll encountered when adding lowering springs. Spohn Sway Bars are larger & stronger 1 5/16" front (solid) & 1" rear (solid) 4140 chrome moly sway bars to reduce body roll and provide predictable handling (matched sizing for balanced handling). Our bar stock is 4140 chrome moly heat treated spring grade steel. The bars are entirely heat formed and coined as one piece. We put our bars through this extensive process to insure that the final product will be the strongest, most durable bar on the market, and that it will be the most resistant to form alteration. Most aftermarket anti-sway bars are cold-bent, making them weaker at the bends, and more vulnerable to shape alteration. Sway bar sets include polyurethane bushings and end links, everything you need for installation and maximum performance! Sway bars are gloss black in color.
