Hellwig's new rear sway bar for the half-ton Chevy Silverado and GMC Sierra fits both the 2wd and 4wd models. This sway bar is made from heat treated, solid chromoly steel to improve handling and safety while reducing body roll in both daily driving and tow/haul conditions. The kit is adjustable to allow for rate tuning to the driver's specific load and driving style. All the components are made in the United States at Hellwig's factory in Visalia, CA and the kit includes everything necessary to complete the installation. This is a direct bolt on kit, requiring no drilling or welding. Availabe for stock ride height and 2-4" lift applications.
