Chevy/GMC 2500HD & 3500HD 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 2500 or 3500 truck stay more level with the road - making for a safer, sturdier, and more enjoyable ride.
