29in Tubular Torsion Bar 1025 Rate Hollow

The 29in Tubular Torsion Bar 1025 Rate Hollow from MPD Racing is purpose-built for sprint car suspension tuning and performance vehicle modifications. This hollow chromoly torsion bar delivers the precise spring rate control that competitive drivers and chassis builders demand when dialing in front-end geometry and load transfer characteristics. Whether you're a weekend racer optimizing your car's handling or a professional mechanic fine-tuning suspension response, this tubular design offers the stiffness-to-weight ratio essential for high-performance applications where every pound matters.

Constructed from chromoly steel with a 1.025-inch outer diameter and hollow core design, the 29in Tubular Torsion Bar 1025 Rate reduces unsprung mass while maintaining torsional stiffness across the 1-1/8-48 inch spline interface. The hollow construction lowers weight to 4.35 lbs—critical for sprint car applications where suspension compliance and responsiveness directly influence cornering grip and acceleration traction. The chromoly material provides superior fatigue resistance compared to mild steel, ensuring consistent spring rate performance through repeated cycles of compression and extension during hard cornering and braking events.

This torsion bar is ideal for sprint car builders and open-wheel racers who require precise anti-roll stiffness adjustment without sacrificing chassis dynamics. The standardized 1-1/8-48 spline connection ensures compatibility with most sprint car front-end suspension assemblies that accept tubular torsion bars of this dimension. Installation involves mounting the bar between the frame's forward and aft anchor points, with spline engagement on both ends; consult your vehicle's suspension geometry documentation to confirm the 1025 spring rate matches your desired handling balance, as torsion bar rates directly control cornering stiffness and weight transfer distribution.
