    Torsion Bars should be installed so that they always twist in the same direction. The bars retain a memory of the direction they are twisting, if they are twisted in the opposite direction the spring rate will be compromised and the bar could fracture. For this reason its always a good idea to mark the torsion bars to ensure they are used in the correct corner of the car.

    Torsion Bar Pre-Stressed Service

    Re-stressing allows bars to have greater elastic twist angle and hence more wheel travel. It also drastically reduces bar settling eliminating a need for a racer to bounce a car up and down in order for it to settle at the correct height. During pre-stressing the bars are twisted within the plastic shear zone over a specific angle, unloaded and repeated two more times.

    The Torsion bars’ strain curves are carefully monitored during the procedure. The procedure causes compressed residual stresses at the outer boundary of a bar increasing its yield strength. Ultimately, this saves time and, more importantly, conditions the bar for immediate on-track use in while also increasing the bars overall longevity.
