Torsion bars provide the vital suspension link between the surface of a race track and a car's chassis. Torsion bars have as much to do with the car's response as do its tires, so their quality and consistency are essential to a good performing car. The quality of material, workmanship, heat treatment and finish all have an effect on the performance of the torsion bar.

Schroeder uses only aircraft quality high alloy steel to achieve the finest bar possible, and machines their torsion bars with state of the art CNC equipment. Only Schroeder torsion bars are machined in one continuous pass from end to end in order to prevent irregularities. Then they are polished, heat treated to exact specifications, then polished again to assure no surface imperfections exist which could cause a stress point or crack to originate. The bars are then coated with a protective film and shipped in plastic screw-lock tubes for protection and easy identification.

Gun drilling allows use of superior materials which will allow the bar to twist faster and store more energy during wind up for quicker response.

  • 1-1/8" x 30" long
  • Gundrilled to ensure a consistent performance
  • Choose your diameter size; .975", .987", 1.000", 1.015", 1.025", or 1.050"

Speedy Tip:

Hollow and Solid Torsion Bars - There are significant differences between gundrilled and solid torsion bars other than their weight.  The hole in the center of gundrilled torsion bars creates two surfaces instead of one, allowing the bar to react differently than a solid bar to deflection.  Gundrilled torsion bars have a faster spring rate than a solid torsion bar, which means they rebound, or spring back, quicker.  The center diameter of a hollow torsion bar is adjusted to achieve the same spring rate as a solid bar.  Therefore, no chassis adjustments need to be made when switching from solid to hollow bars. 

Schroeder gundrilled and solid torsion bars all start the same way, as aircraft quality high alloy steel stock, and the gundrilled bars are drilled out using the same high performance equipment used to machine the barrels of fine rifles.  Track conditions and chassis characteristics determine which type of bar is the best choice for your particular application.
