Flex-a-lite 1 Inch Fan Spacer Kit - Aluminium spacer with matched bolts & washers, stackable up to 3

The Flex-A-Lite 1 Inch Fan Spacer Kit (14548) is an aluminum spacer and hardware set that positions belt-driven cooling fans correctly to protect the fan and maintain cooling performance.

When installing a belt-driven radiator fan, correct spacing is essential to avoid contact, reduce stress on the fan center star, and preserve airflow. This 1-inch spacer from Flex-A-Lite is machined for a broad load-bearing surface and softened edge radius to minimize point loads and stress cracking. It includes the matching bolts and washers and fits systems using a 5/8-inch pilot hole, allowing installers to stack up to three spacers to reach the ideal fan offset for a variety of engines and fan assemblies.

How does the spacer protect my radiator fan and center star?

The spacer increases the distance between the fan hub and mounting face, reducing rubbing and direct edge load that can crack the fan’s center star. Its large bearing surface distributes forces evenly while rounded edges prevent sharp contact points.

• Aluminum construction resists corrosion while carrying load
• Soft-radius machining reduces stress concentrations on the fan center
• Large bearing surface disperses force to avoid point loading
• Compatible with Flex-A-Lite belt-driven fan designs

What hardware and fit features are included for installation?

The kit comes ready to mount: it contains the spacer, bolts, and washers sized to the spacer’s 5/8-inch pilot hole. That means you won’t need to hunt for fasteners or adapters when fitting a Flex-A-Lite belt-driven fan to your vehicle, simplifying installation.

• Includes bolts and washers matched to the spacer
• 5/8-inch pilot hole aligns with common Flex-A-Lite fan hubs
• Stackable up to three 1-inch spacers for flexible offsetting
• Designed for belt-driven fan assemblies rather than electric fan conversions

How many spacers can I use, and why stack them?

You can install up to three of these 1-inch spacers in series to increase clearance as needed. Stacking lets you fine-tune blade-to-shroud distance, helping you achieve optimal airflow without interfering with shrouds, radiators, or accessory pulleys.

• Use a single spacer for minor adjustments
• Two or three spacers provide greater offset for deep shrouds or recessed fan mounts
• Maintains consistent load distribution even when stacked
• Prevents fan blade contact across varying engine bay geometries

Does the spacer come with any warranty or reliability assurances?

Flex-A-Lite backs this spacer kit with a one-year manufacturer warranty, offering coverage against defects in materials and workmanship. The durable aluminum build and precision machining are intended for long-term service when installed correctly.

• One-year manufacturer warranty for peace of mind
• Machined aluminum resists wear and environmental damage
• Designed specifically for compatibility with Flex-A-Lite belt-driven fans
• Follow manufacturer installation guidance to preserve warranty

Who is this for: The Flex-A-Lite 1 Inch Fan Spacer Kit is aimed at DIY mechanics, performance enthusiasts, and professional technicians who fit belt-driven cooling fans and need a reliable method to correct fan offset. It’s particularly useful when shrouds, radiator placement, or aftermarket accessories interfere with proper blade clearance. If you use Flex-A-Lite belt-driven fans or are adjusting mechanical fan position for reliable airflow and reduced stress on fan components, this spacer kit provides a straightforward, durable solution.
