UltraCool UC-SMT8-6N Lower Fairing Mounted Oil Cooler Kit for Harley-Davidson Touring 17-24 w/Lower Fairing

This UltraCool Oil Cooler 3.0 kit is designed for 2017-2024 M8 Touring Models with Twin-Cooled Engines or non-liquid cooled M8 engines with 2017-2024 OEM lower fairings or aftermarket OEM copy lower fairings. It also fits 2017-2025 Tri Glide Ultra models.  This kit DOES NOT fit with the 2025 and newer style Harley lower fairings.

Note: The M8 “Liquid Cooled” engines only cool the exhaust ports, and the stock system is not sufficient to prevent overheating during city riding or traffic. By adding the FLO Oil Filter and UltraCool Oil Cooler 3.0, you can give your M8 engine 60 degrees of cooling power and the performance of a FULLY liquid-cooled system!

The stock cooling system on the M8 engines is not designed to handle the heat during slow riding or heavy traffic. The UltraCool 3.0 Oil Cooler significantly improves cooling efficiency, providing you with the same benefits as a full liquid-cooling system.

Key Features of the UltraCool Oil Cooler 3.0
• Fits M8 Engines with Lower Fairings: This kit works with FLH Milwaukee 8 Frames (2017-2024) including Twin-Cooled or non-liquid cooled engines equipped with 2017-2024 OEM lower fairings or aftermarket copies. It also fits 2017-2025 Tri Glide Ultra models.
• “Naked” Side Mount Version: The cooler features a sleek, uncovered design that fits neatly into the left lower fairing air door after modification for a clean look.
• Thermal Control with Dual Fans: The 3.0 Oil Adapter and Thermal Switch automatically activates the dual fans when your oil reaches 210°F, continuing until the oil is cooled to 185°F. The goal is to maintain an optimal oil temperature between 200-230°F for maximum engine protection.
• High-Efficiency Cooling: The specially designed dual-pass aluminum heat exchanger with turbulators maximizes heat dissipation, keeping your engine cooler even in the most challenging conditions.
• Sealed, Waterproof IP68 Dual Fans: The dual fans produce a powerful 220 CFM of airflow to keep your engine’s oil at a safe temperature.
• Easy Installation: The plug-and-play wiring harness with relay and waterproof connectors connects directly to the battery under the seat, making installation a breeze.
• Durable Oil Lines: Black nylon-coated stainless steel braided oil lines with AN6 fittings offer strength, durability, and resistance to wear.
• LED Indicator Light: A built-in LED light shows when the fans are operating, so you’ll know when cooling is active.
• Included Accessories: The kit includes an LED mount, special oil line fitting wrench, and detailed instructions to help you complete the installation.

Additional Recommendations
• For best results, we recommend using FLO Oil Filters (PCS4B, PCS4C, or PCS4BC) for added cooling and easier maintenance. These filters are designed for a tighter fit with the UltraCool Lower Fairing Mounted Oil Cooler, making oil changes hassle-free.
• You may also need the electrical connector #SMB-Y128 for specific installations.
