Why 4130 Chromoly?

4130 chromoly steel offers an exceptional strength-to-weight ratio compared to mild steel, making it the material of choice for performance steering and drivetrain components. Its high tensile strength resists flex and fatigue under the torsional loads of steering input, while the hollow construction keeps weight to a minimum — critical in race and custom builds where every gram counts.

3/4-48 Spline Standard

The 3/4-48 spline specification is a widely adopted standard in the custom steering and shifter industry, ensuring broad compatibility with aftermarket universal joints, couplers, and steering components from leading manufacturers. Both ends are splined, giving you maximum flexibility when cutting to length and fitting to your specific application.

Note: Shaft can be cut to length to suit your specific build requirements. Always verify spline compatibility with your universal joints and couplers before ordering.
