Ford F250 & F350 2wd (w/Dana 70 rear axle) Anti-Sway Bars by Hellwig are an easy and affordable way to upgrade your vehicles handling performance. The torsional effect of the sway bar will significantly reduce sway and body roll. The sway bar will help to transfer the pressure on the outboard wheels and apply opposite pressure on the inboard wheels. Weight is more evenly distributed to all four wheels helping your Ford F250 or 350 stay more level with the road - making for a safer, sturdier, and more enjoyable ride.
