Product Description

*April 2016: We are pleased to announce our 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 2016 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 4340 aircraft grade alloy steel, before being heat treated, centerless ground, pre-stressed and finally 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. This means you get virtually no settling and no more bad bars. Specific to our Sprint Car series bars is our quick safety clip ends, which rest inside a groove along the outside of the splines. These fast and easy to use safety clips meet all safety requirements and 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 may be used in the left front or right rear and bars marked RFLR, may be used in the right front or left rear.
