Flex-a-lite 1 Inch Fan Spacer Kit — Aluminum 14548, Stackable to 3 in, Includes Bolts

The Flex-A-Lite 1 Inch Fan Spacer Kit (14548) is an aluminum shim designed to correctly position belt-driven radiator fans, protecting the fan center and restoring optimal airflow.

When a belt-driven cooling fan sits too close or too far from the radiator or shroud, it can reduce airflow efficiency or stress the fan hub. This one-inch spacer creates the precise offset needed for proper fan alignment in Flex-A-Lite belt-driven fan systems. Machined from aluminum with a radiused edge and a wide load-bearing face, it reduces point loading on the fan center star and helps prevent stress cracks while improving clearance and airflow performance.

How does the spacer protect my fan and radiator?

By increasing the distance between the fan hub and its mounting surface, the spacer spreads load over a larger area and eliminates sharp contact points. The radiused edge is finished to minimize stress concentrations that can lead to cracking in the fan center star.

• Large load-bearing surface reduces concentrated pressure on the fan hub.
• Soft radius machined around edges prevents stress risers and cracking.
• Aluminum construction resists corrosion while remaining lightweight.
• Use with original bolts/washers included for secure installation.

Will I need more than one spacer to get the right clearance?

Yes — the kit is modular so installers can stack up to three 1-inch spacers to achieve the desired offset. This flexibility allows fine-tuning of fan position without altering existing engine components or fabricating custom parts.

• Single spacer yields a 1-inch offset; up to three can be combined for up to 3 inches.
• Stackable design maintains alignment and load distribution across spacers.
• 5/8-inch pilot hole ensures a centered fit on standard fan hubs.
• Comes with the bolts and washers required for typical installations.

What hardware and fit details should I know before installing?

The spacer includes the mounting bolts and washers so you won’t need extra fasteners for most installs. It features a 5/8-inch pilot hole to locate the spacer concentrically on the fan center, ensuring proper balance and alignment.

• Includes bolts and washers sized for common Flex-A-Lite belt-driven fan mounts.
• 5/8-inch pilot hole centers spacer on the fan hub to prevent misalignment.
• Aluminum construction keeps added weight minimal and resists corrosion.
• Compatible with Flex-A-Lite belt-driven fan center stars and mounting geometry.

Is there warranty or support if something goes wrong?

Flex-A-Lite backs this spacer kit with a one-year manufacturer warranty that covers defects in materials and workmanship. For fitment questions or warranty service, contact Flex-A-Lite customer support or your authorized retailer with the product code 14548.

• One-year manufacturer warranty for peace of mind.
• Product code 14548 identifies the exact spacer kit for support requests.
• Documentation and installation guidance available from Flex-A-Lite resources.
• Retailer or manufacturer support for warranty claims and compatibility checks.

Who is this for? The Flex-A-Lite 1 Inch Fan Spacer Kit is aimed at DIY mechanics, restoration enthusiasts, and professional installers working with belt-driven cooling fans who need a reliable, serviceable way to correct fan position without modifying engine components. If you’re fitting a Flex-A-Lite belt-driven fan and require precise offset, less hub stress, and a bolt-on solution, this spacer kit provides a simple, durable option backed by a manufacturer warranty.
