Steering Shaft Collapsib le Shaft 18-1/2in Long

The BORGESON Steering Shaft Collapsible Shaft 18-1/2 inch long is a precision-engineered steering component designed for vehicles requiring compact, safety-focused steering geometry. This collapsible shaft incorporates a 3/4-inch double D connection interface, allowing it to adapt to a range of steering column configurations while maintaining mechanical integrity under normal driving conditions. Constructed from steel with a natural finish, this shaft meets the functional requirements of modern automotive and light-duty vehicle applications where steering safety and column collapse energy absorption are critical design considerations.

At 18-1/2 inches in length with a compact 1.75-inch outer diameter, this collapsible steering shaft is engineered to fit within standard steering column envelopes while delivering the steering response and mechanical precision expected in professional vehicle applications. The double D shaft interface ensures positive engagement with compatible universal joints and coupling components, eliminating rotational slip during acceleration, braking, and cornering maneuvers. Weighing 2.21 pounds, the assembly balances structural rigidity with practical weight management, a consideration for vehicles where unsprung mass and inertial loads affect handling dynamics.

This component serves applications where OEM steering columns have been modified, replaced, or upgraded—including vehicle restorations, custom builds, and fleet maintenance scenarios. The collapsible design provides the safety benefit of energy absorption in frontal impact events, a feature that distinguishes modern steering systems from rigid installations of earlier decades. Technicians and builders selecting a replacement or upgrade steering shaft should verify fitment against existing universal joint interfaces and steering box input connections before ordering.

BORGESON is recognized in the automotive aftermarket for steering and suspension components that prioritize mechanical fit and safety compliance. The natural steel finish of this shaft requires corrosion protection consistent with standard automotive maintenance practices, particularly in salt-air or high-moisture environments where bare steel oxidation accelerates.
