BD Diesel Xtrude Double Stacked Transmission Cooler Kit - Universal 1/2in Tubing

If you're pushing your truck hard, whether it's for towing heavy loads, hitting the track, or just dealing with extreme heat, keeping your transmission oil cool is critical. This BD Diesel Xtrude Double Stacked Transmission Cooler Kit is designed to significantly improve your transmission's cooling capacity. It replaces your factory cooler with a much more robust system, capable of handling the demands of high-performance applications and heavy-duty use across a wide range of trucks, including models like the Dodge Ram 2500/3500 and Ford F-250/F-350 Super Duty.

What sets this kit apart is its double-stacked core design, which offers over 40,000 BTU/HR of cooling power and achieves more than a 350% temperature drop compared to stock systems. That's a 36% improvement over BD's standard single-core kit. The cooler features 200-micron extruded passages for a large surface area to transfer heat efficiently, and a turbulent oil flow design ensures thorough cooling. The large 5/8-inch ports minimize restriction, and the furnace-brazed rails are tested to withstand up to 300psi of pressure. It also includes a thermostatically controlled 10-inch electric fan that kicks in automatically to maintain optimal oil temperatures.

BD Diesel makes installation as straightforward as possible with this kit. It comes complete with all the necessary fittings, clamps, hoses, and hardware. You also get a build-it-yourself galvanized bracket kit, saving you the hassle of fabricating custom mounts. The pre-wired, loomed harness features fuse and relay protection with OEM-style sealed connectors for a clean, factory-like installation that resists the elements. This kit is a solid option for anyone looking to protect their transmission from heat-related damage and ensure reliable performance under demanding conditions.
