Precision Steel Tubing in Automotive Suspension Systems

A vehicle’s suspension system is group of mechanical components that connect the wheels of the vehicle to the frame or body. Typically, the suspension system consists of three basic components: springs, linkages and shock absorbers that help to isolate the vehicle chassis from sudden vertical displacements of the wheel assemblies during driving. Along with improving the ride and handling of the vehicle, passenger safety and comfort has required a great amount of engineering and innovation for suspension system designers. The use of precision steel tubing in vehicle suspension systems allows for the strength required for performance and safety standards to be met without adding extra weight to the vehicle. Steel tubing is best used in the following suspension system applications:

  • Shock absorbers
  • Tie rods
  • Struts
  • Sway bars
  • Bushings/rings/fasteners
  • Hydraulic cylinders


When selecting tubing for vehicle suspension system design, it’s important to specify a material that features high-strength, high-wear resistance and maximum protection against oxidation and corrosion. Plymouth Tube supplies specialty carbon, alloy and stainless steel tubing solutions that offer these advantages to the vehicle suspension system manufacturer. With over 95 years of industry experience, Plymouth’s team of technical experts can work with decision makers to assist in material selection for all automotive components, including suspension systems.
