Torsion Bar Reamer 1.125 Taper For Sprint Car Bar

The MPD RACING Torsion Bar Reamer 1.125 Taper for Sprint Car Bar is a precision honing tool engineered for competitive sprint car suspension tuning. This 1.125 inch-per-foot taper reamer is purpose-built to accurately enlarge and finish torsion bar bores, enabling fine adjustments to suspension stiffness and handling characteristics critical in high-speed oval track competition.

Constructed from aluminum and finished in black anodize, this reamer measures 18.35 inches in overall length—a dimension that accommodates both standard and extended torsion bar applications. The 1.125 taper specification allows controlled material removal while maintaining bore concentricity, essential for balanced suspension response across both left and right sides of the chassis. The black anodized finish protects the tool from corrosion during storage and frequent use in shop environments. At 2.72 lbs, the reamer is manageable for hand-operated or machine honing setups common in sprint car garages.

This tool is designed for sprint car builders and suspension technicians who need to customize torsion bar rates beyond factory options. Lightweight rear-wheel-drive race cars depend on precise torsion bar geometry to achieve the roll stiffness and compliance balance required for competitive cornering. A properly sized and finished torsion bar bore ensures the bar seats correctly and performs predictably lap after lap. The MPD Racing reamer is the appropriate choice for shops working with modern sprint car platforms that rely on torsion bar suspension tuning as a primary setup variable.
