BD Diesel Xtrude Double Stacked Transmission Cooler Kit - Universal 5/8in Tubing

BD Diesel is known for making tough parts for trucks that work hard, and this Xtrude Double Stacked Transmission Cooler Kit is no exception. If you're pushing your vehicle hard, whether it's for towing, racing, or just heavy-duty work, keeping your transmission oil cool is critical to prevent damage and ensure consistent performance. This kit is designed to handle that challenge, offering a significant upgrade over stock cooling systems for a wide range of trucks, including models like the Chevrolet Silverado 2500 HD and GMC Sierra 3500.

This cooler uses a double-stacked core design, which means it has a much larger surface area to transfer heat away from your transmission fluid. It's rated to deliver over 40,000 BTU/HR of cooling and can achieve over a 350% temperature drop compared to your factory setup. That's a 36% better temperature drop than BD's standard single-core kit. The 5/8-inch ports are large to prevent any restriction in oil flow, and the furnace-brazed rails are tested to hold up to 300 psi. Inside, the turbulent oil flow design helps ensure the fluid is thoroughly cooled as it passes through the extruded passages.

BD Diesel includes everything you need to get this installed. You get all the necessary fittings, clamps, hoses, and hardware. The kit also comes with a build-it-yourself galvanized bracket kit, which saves you time fabricating custom mounts. For automatic temperature control, a thermostatically controlled 10-inch, 800 CFM electric fan is included. The pre-wired, loomed harness features fuse and relay protection with OEM-style sealed connectors for a clean, reliable installation. This kit is a solid choice for anyone serious about protecting their transmission under demanding conditions.
