An immediate improvement will be felt when you drive through the first corner with a Hellwig Sway Bar installed. Best of all, with its simple bolt on design these kits can be installed with common hand tools (some kits may require drilling). Do it yourself or have a professional install it. Either way you get outstanding performance. Hellwig sway bar systems enable Chevy Avalanche drivers to handle wind, passing trucks, winding roads and everyday driving with more confidence, control and stability.
