Torsion Bars

Torsion Bars

Let's cover the basics:  A torsion bar is a flexible spring that moves about its axis via twisting.  It works by resisting the torque placed on it.  Adjusting the height of the torsion bar affects how the vehicle rides because of the new angle of the control arm.  Speedway Motors offers torsion bars in a variety of lengths and splines to fit your application.  We also offer industry leading technical support to help with any adjustments.
