Hellwig; 1" Diameter; 4140 Chrome Moly Steel w/ Poly Bushings
Hellwig sway bars offer quick bolt-on installation that's engineered to perform. An immediate improvement will be felt when you drive through the first corner with a Hellwig Sway Bar installed. Though most vehicles come equipped with factory installed sway bars, they are often insufficient for today's load and tow demands. Hellwig sway bars feature larger than stock diameters and precision engineered components to optimize handling and reduce body roll. Every Hellwig Sway Bar is designed for a specific vehicle; Hellwig sway bars are not universal fit kits and Hellwig does not weld any fixtures or tabs to its alloy sway bars.
  • Reduces body roll so you benefit from better vehicle control
  • Greatly improved cornering traction for safer driving and cornering capabilities
  • Distributes weight evenly
  • Every sway bar is developed for your specific application
  • Fast, easy bolt on installation with simple hand tools (some kits may require drilling)
  • High quality 4140 chromolly steel
  • High tech polyurethane bushings
How To Determine Stabilizer (Sway) Bar Diameter

To determine Stabilizer (Sway) Bar diameter, measure the bar next to the bushing (toward the center of the vehicle), utilizing one of the methods below.

  1. Use a digital caliper or micrometer for a precise reading
  2. Use an open end wrench that fits snug around the bar, or tighten an adjustable wrench around the bar, and then measure the span opening
  3. Wrap a piece of non-stretchable tape (like masking tape) around the bar to get the circumference. Circumference divided by Pi (3.14) = Diameter. In the example below, the tape measured 3 5/8". 3 5/8 = 29/8 = 3.63 inches. Diameter = 3.63/3.14 = 1.15 inches.
