Reducer Bushing 1-3/4in to 1-1/2in

The JOES Racing Products Reducer Bushing 1-3/4in to 1-1/2in (MPN 13002) is an essential flow-control component for high-performance cooling and fuel system plumbing. Whether you're upgrading radiator hose diameters, stepping down inlet sizes on performance headers, or adapting legacy cooling lines to modern components, this reducer bushing bridges the gap between mismatched hose or tube sizes. Built by JOES Racing—a trusted name in motorsports fabrication—this adapter is ideal for street machines, track cars, and competition builds where precise system routing demands reliability and clean transitions.

Engineered with precision tolerances, the reducer bushing steps flow from a larger 1-3/4-inch diameter down to a compact 1-1/2-inch outlet, minimizing turbulence and maintaining steady pressure throughout your coolant or fuel circuit. The stepped design reduces dead zones where sediment or air can collect, critical for preventing hot spots in high-output engines or vapor lock in fuel systems running elevated temperatures. This compact adapter measures just 3.7 inches in length and weighs only 0.03 lbs, making it ideal for tight engine bay installations where space and weight matter. The smooth internal transition ensures your system flows efficiently without the pressure spikes and cavitation issues that sharp reducers can cause.

Racers and serious mechanics rely on JOES reducer bushings when custom-fitting cooling and fuel systems to frame-off restorations, engine swaps, or radical modifications. This particular 1-3/4in to 1-1/2in size works seamlessly with aftermarket radiators, remote-mounted water pumps, fuel cell systems, and vintage or contemporary hose assemblies. Installation is straightforward—simply select the appropriate hose clamps or compression fittings for your application and secure both ends. For best results, ensure smooth hose routing and avoid sharp bends; pair with quality silicone or braided hose rated for your system's operating pressure and temperature.
