Description
If you’re fabricating a custom steering setup or rebuilding a race car with non-standard shaft diameters, you need a coupler that bridges the gap between your steering column and gear box without compromise. This weld-on steel coupler handles the transition from 5/8″ 36-spline to 3/4″ smooth shaft—a common requirement in tube-frame chassis and custom builds where off-the-shelf solutions fall short. Precision-engineered for direct power transfer, it eliminates play and ensures your steering input translates directly to wheel response.
