Drive Shaft Steel 28in Hollow 10/16 Spline

The MPD Racing Drive Shaft Steel 28in Hollow 10/16 Spline (Model MPD65104) is a purpose-built hollow drive shaft engineered for sprint car racing and high-performance motorsport applications. This 28-inch shaft delivers the lightweight rotational efficiency demanded by competitive drivers while maintaining the structural integrity required for demanding track conditions.

Constructed from steel in natural finish, the 10/16 spline configuration provides secure mechanical coupling at both ends while minimizing unsprung weight. The hollow design reduces rotational mass without sacrificing torsional rigidity, a critical balance in sprint car powertrains where every fraction of a pound affects acceleration response and fuel economy. At 4.78 lbs and spanning 28.25 inches in installed length, this shaft fits within standard sprint chassis geometry while optimizing the power delivery from engine to rear axle. The 1.7-inch outer diameter and 1.55-inch inner dimension are consistent with MPD Racing's precision manufacturing tolerances, ensuring concentricity and eliminating run-out issues that compromise reliability during high-RPM operation.

Sprint car teams and high-performance enthusiasts select hollow drive shafts when weight reduction and rotational efficiency directly impact lap times and overall vehicle dynamics. This shaft is ideal for drivers building competitive sprint car platforms or upgrading from heavier solid-shaft designs. The 10/16 spline pattern is a standard in the sprint car community, ensuring compatibility with most contemporary rear ends and transmission output flanges.

MPD Racing is recognized in sprint car racing circles for manufacturing precision drivetrain components that meet the demanding specifications of competitors and teams. Proper installation requires alignment verification and torque specifications per your chassis builder's or engine manufacturer's recommendations.
