Steering Box Sportsman Input Spline 3/4-30

The Steering Box Sportsman Input Spline 3/4-30 is a precision steering component engineered for high-performance and racing applications where responsive, reliable steering control is non-negotiable. Built by SWEET—a trusted name in performance steering systems—this input spline assembly delivers the mechanical foundation required for drivers who demand immediate feedback and zero play in their steering geometry. Whether you're building a circle-track racer, drag car, or road course machine, this component ensures your steering input translates directly to wheel movement without lag or slop.

The 3/4-30 spline specification refers to the input shaft interface—a 3/4-inch diameter shaft with 30 splines, a common standard in modern performance steering boxes designed for both manual and power-assisted setups. This design minimizes backlash and distributes loads evenly across multiple teeth, critical when operating at elevated steering inputs under aggressive driving conditions. The precision machining and tight tolerances inherent to SWEET's manufacturing ensure consistent engagement with your steering column coupler, while the robust spline geometry resists wear and maintains steering integrity through countless race events or high-demand street applications.

This input spline assembly is ideal for fabricators, race teams, and enthusiasts building or upgrading Sportsman-class vehicles in circle-track, oval, or drag racing venues. Installation pairs this component with a compatible steering box housing and input shaft coupler—verify spline count and shaft diameter before ordering to ensure proper fit with your specific steering column and box assembly. At 24.35 lbs, the casting weight reflects a substantial, production-grade component built to withstand years of high-stress operation, making it a sound investment for anyone serious about steering performance and durability.
