1/2in Fan Spacer Kit

The DERALE 1/2in Fan Spacer Kit (part number 31500) is a precision cooling system component designed to optimize electric fan clearance and performance in V8-powered vehicles. This aluminum spacer increases the distance between the fan and radiator, improving airflow efficiency and reducing thermal interference—a critical consideration for high-performance cooling setups in Chevy V8 and Ford V8 engines where stock spacing proves inadequate for aftermarket fans or modified cooling configurations.

Constructed from clear-anodized aluminum, the spacer resists corrosion while maintaining a lightweight profile at just 0.45 lbs. The 1/2-inch thickness provides the precise spacing needed to prevent radiator obstruction while allowing maximum air velocity through the core. All necessary bushings and hardware are included, ensuring a complete installation without additional sourcing. Anodized finishing protects against oxidation, a key advantage in environments where moisture exposure or salt air could compromise untreated aluminum components.

This spacer kit addresses a specific cooling challenge: factory fan mounts often position fans too close to the radiator, creating dead zones where air cannot flow efficiently. Engine builders, enthusiasts upgrading to larger-diameter or shrouded fans, and owners running tighter engine bays benefit from precise spacing control. The DERALE 1/2in Fan Spacer Kit is essential for maintaining proper cooling system performance when modifying fan selection or repositioning cooling equipment.

Proper fan spacing directly impacts thermal management—inadequate clearance reduces airflow volume, raising coolant temperatures under load. The 1/2-inch offset provided by this kit restores the margin needed for efficient convection cooling, particularly in vehicles with composite radiators or modern shroud designs. DERALE's reputation in thermal management makes this spacer a reliable choice for builders who require validated cooling solutions.
