Sprint Torsion Bar RFLR 975 Rate 30in

The SWAY-A-WAY Sprint Torsion Bar RFLR 975 Rate 30in is a precision-engineered suspension component purpose-built for sprint car competition. Manufactured from chromoly steel with a 0.975-inch outer diameter and 30-inch length, this right front / left rear application torsion bar delivers the stiffness tuning critical for balanced handling on dirt and asphalt racing circuits. The red powder coat finish provides corrosion resistance across multiple race seasons while the 1-1/8-48 inch spline interface ensures secure, repeatable installation in sprint chassis.

Sprint car suspension tuning demands precision. The 975-rate specification on this SWAY-A-WAY torsion bar designates its torsional stiffness per degree of twist—a critical metric for controlling chassis roll and maintaining consistent tire loading through turns. Chromoly construction provides superior strength-to-weight compared to standard steel, allowing racers to dial in handling adjustments without excess unsprung mass. The spline design enables quick swaps during event weekends when track conditions shift or setup refinement is needed. Weight of 4.02 lbs keeps the front suspension nimble while maintaining the rigidity required for competitive edge.

This torsion bar is engineered for racers who understand that suspension geometry determines lap times. Whether adjusting for increasing track temperatures, driver preference changes, or competitive class requirements, the 975-rate stiffness sits in the tuning window preferred by many sprint car teams. The right front / left rear configuration provides the lateral control balance necessary on both clockwise and counterclockwise layouts. Serious competitors rely on SWAY-A-WAY components to isolate suspension variables and focus on driver performance and fuel strategy rather than chassis guessing.
