Description
Product Overview
Flex a lite 2in Mopar fan spacer is engineered to deliver a precise, machined fit for a wide range of Mopar engines. Constructed from high‑grade aluminum alloy, the spacer combines lightweight construction with exceptional strength, ensuring it can withstand the demanding thermal cycles of automotive cooling systems. The exterior finish is machined for a clean, professional appearance that matches OEM standards, while the internal dimensions are calibrated to the manufacturer part number 14536, guaranteeing seamless integration with existing fan assemblies.
Measuring 5 × 10 × 6 inches and weighing only 15.5 ounces, the spacer adds minimal mass while providing the critical 2‑inch offset required for optimal airflow. This offset creates a larger gap between the fan and the radiator, allowing air to move more freely and reducing turbulence that can lower cooling efficiency. The design also helps to align the fan blades more accurately with the shroud, improving overall pressure balance and extending the life of both the fan and the cooling system.
Compatibility is a core focus of the Flex a lite fan spacer. It is listed as compatible with the 2in Mopar Spacer Kit and aligns with the OEM part number 14536, making it a direct replacement for the original component. The part number FLE108431 ensures that distributors and service technicians can quickly identify the correct item, reducing the risk of ordering errors. This compatibility extends to a variety of Mopar models, providing a versatile solution for both professional garages and DIY enthusiasts.
Beyond the core specifications, the spacer features a corrosion‑resistant coating that protects against moisture and road salt, extending service life in harsh environments. The precision engineering also minimizes vibration transmission, which can improve overall vehicle comfort and reduce wear on adjacent components. Each unit undergoes rigorous quality testing, including dimensional verification and stress analysis, to ensure consistent performance across production batches.
For customers seeking to upgrade their cooling system, the spacer offers a cost‑effective method to increase airflow without the need for a complete radiator replacement. Its compact size fits within existing engine bays, and the lightweight design contributes to marginal fuel efficiency gains. The product’s design philosophy emphasizes simplicity, reliability, and performance, making it a trusted choice for performance‑oriented builds and everyday driving alike.
Usage
The Flex a lite 2in Mopar fan spacer is ideal for installation in performance‑oriented street vehicles as well as heavy‑duty trucks that demand reliable cooling under high load conditions. By creating a larger airflow channel, the spacer assists in maintaining lower engine temperatures during prolonged highway cruising, aggressive acceleration, or towing operations. Mechanics appreciate the straightforward bolt‑on installation, which typically requires only the removal of the existing fan assembly, placement of the spacer, and re‑attachment of the fan using the original hardware.
Because the spacer is fabricated from corrosion‑resistant aluminum, it performs well in humid climates and resists the buildup of rust that can affect steel components. It is also compatible with aftermarket shrouds and can be paired with high‑flow radiators for enthusiasts seeking maximum cooling capacity. When combined with a properly tuned fan speed controller, the spacer contributes to a balanced cooling system that protects engine components while minimizing unnecessary power draw from the alternator.
In real‑world applications, the spacer has been reported to lower engine bay temperatures by up to 10 °F in demanding conditions, translating to improved engine longevity and reduced risk of overheating. The increased airflow also benefits turbocharged and supercharged engines, where heat management is critical for maintaining boost pressure and preventing detonation. Users have noted smoother fan operation with reduced noise levels, as the spacer helps to dampen vibration transmitted through the fan assembly.
Installation does not require specialized tools; a standard socket set and torque wrench are sufficient to secure the fan bolts to factory specifications. The spacer’s design includes pre‑drilled mounting holes that align precisely with OEM bolt patterns, eliminating the need for drilling or modification. For vehicles equipped with electronic fan control modules, the spacer does not interfere with sensor placement, ensuring that the existing control logic remains functional.
Maintenance of the spacer is straightforward. Periodic visual inspection for debris accumulation and cleaning with mild detergent will keep the surface free of contaminants that could impede airflow. The aluminum construction tolerates typical automotive cleaning agents, and the machined finish resists scratching, preserving both aesthetics and performance over the product’s lifespan.
