Sprint Car Torsion Bar – 30″ Pre-Stressed

Sway-A-Way’s Sprint Car Torsion Bars are manufactured out of heat-treated 4340 alloy steel and are the only pre-stressed sprint car torsion bars on the market. Pre-stressing eliminates virtually all settling prior to installation and significantly increases the torsion bars available twist before yield.

We are pleased to announce our continuing partnership with Pauch Racing and Kenny Tremont. Billy Pauch Sr., Billy Pauch Jr., and Kenny Tremont will be running Sway-A-Way dirt modified torsion bars for the 2018 circuit. Keep it locked on our blog for race results and updates!

Sway-A-Way’s circle track torsion bars are superior quality bars manufactured for improved, more consistent, racing performance. These tough bars are precision machined from alloy steel and powder coated. Unique to Sway-A-Way’s torsion bars is its proprietary pre-stressing operation which significantly increases the torsion bars strength and allows for more wheel travel before yielding. The final product is a torsion bar that is race ready out of the box and has already proven itself on Sway-A-Way’s custom dyno, eliminating the risk of a bad torsion bar.

Sway-A-Way’s Sprint Car Torsion Bars are manufactured with a clip groove at the end of the splines to accept our included safety circlips. These fast and easy to use safety clips meet all track safety requirements and are approved for use in the World of Outlaws series. The safety clips included with all Sway-A-Way Sprint Car torsion bars are rated for 7,000lbs of axial load.

Due to our pre-stressing operation, Sway-A-Way’s circle track torsion bars are orientation specific. This means for Sprint Cars bars marked LFRR, the bar may be used in the left front or right rear and bars marked RFLR, may be used in the right front or left rear.

Note: The torsion bar can be flipped end for end as long as it stays on the corner it was preset for.
