Aluminum Bearing Spacer for Wide 5 Hub

The aluminum bearing spacer for Wide 5 hub applications is a precision component engineered for high-performance wheel assembly on vintage and custom vehicles. Whether you're building a hot rod, restoring a classic truck, or upgrading a race car, this spacer maintains proper bearing preload and axial alignment on Wide 5 lug patterns—a standard found across American muscle cars, drag racers, and street rods. Proper bearing spacing is critical to wheel longevity, handling integrity, and safety at speed.

Manufactured from aluminum and finished in black anodize, this bearing spacer resists corrosion while remaining lightweight—a key advantage in performance applications where unsprung weight directly affects suspension response and fuel economy. The anodized coating provides durability against moisture, salt, and road chemicals without adding significant mass; at 0.3 lbs per unit, it contributes minimal rotational inertia. The spacer's precision bore and shoulder design ensure consistent bearing preload geometry, which is essential for reducing radial and lateral play that would otherwise accelerate bearing wear and compromise wheel stability.

Buyers restoring or modifying Wide 5 hub assemblies—including vintage Mopar, Ford, and Chevrolet platforms—will find this spacer indispensable for proper wheel installation. It is sold individually, so confirm your wheel count and bearing configuration before purchase. Installation requires basic mechanical skill and proper torque specification per your vehicle's service manual; incorrect preload can result in bearing failure or wheel lockup. Pair this spacer with quality roller bearings and a compatible hub assembly for optimal performance and reliability on the street or track.
