Rack & Pinion Adapter 3/4 O.D. 26-Spline

The MEZIERE Rack & Pinion Adapter 3/4 O.D. 26-Spline (model RP02) is a precision steering component designed to interface aftermarket rack and pinion systems with original equipment or custom steering columns. This adapter converts a 3/4-inch outer diameter input shaft to a 9/16 x 26-spline connection, enabling seamless integration between modern power steering conversions and classic or custom vehicle architectures. The steel construction and natural finish provide corrosion resistance suitable for both street and race applications.

Compact dimensions of 1.35 x 1.35 x 3.05 inches and minimal weight of 0.15 lbs ensure this adapter installs without adding significant mass or complicating underhood packaging. The 26-spline engagement provides reliable torque transfer and indexing during steering input, a critical requirement when converting traditional manual steering systems or adapting non-original steering columns to modern rack and pinion assemblies. The precise bore and spline geometry mean fitment is exact, eliminating play and maintaining steering feel.

This adapter is engineered for restoration shops, hot rod builders, and automotive engineers performing steering system conversions on classic cars, custom builds, and engine swaps where OEM columns must connect to modern steering racks. It is particularly valuable in applications involving V8 conversions, frame-off restorations, or aftermarket power steering upgrades where spline incompatibility between donor and recipient components would otherwise require custom fabrication. MEZIERE is recognized in the performance automotive sector for precision steering components that meet tight tolerances required in racing and high-performance applications.
