This is the strongest, most bullet proof rear sway bar in the market. This sway bar is a full steel solid 1" bar!  And it's the last rear sway bar you will ever have to buy for your foxbody because it has a lifetime warranty! The stock sway bar's ends and many aftermarket replacements as well are smashed flat from the same piece of round tubing that makes up the rest of the bar. This process significantly reduces the structural integrity of the material, hence why the factory sway bar breaks in this area and most aftermarket sway bars as well.

This sway bar has thick billet steel ends welded onto the ends of the bar. No smashing of the ends. Billet steel ends are far stronger than the resulting smashed ends and welding them to the bar makes for a far stronger point of connection. This eliminates the inherent weakness of the factory and many aftermarket designs.  Plus, new grade 10.9 mounting hardware.

Note: Does not fit 99-04 IRS Cobra
