The BD Diesel 1030606-DS-58 is a heavy-duty auxiliary transmission cooler kit designed to improve cooling efficiency in demanding fleet and automotive applications. Engineered with double stacked cores, this cooler delivers over 40,000 BTU per hour of cooling capacity, significantly reducing transmission fluid temperatures and enhancing overall drivetrain longevity. The large surface area of the cooler promotes efficient external air flow cooling, while the turbulent oil flow design ensures a more complete heat transfer process. This kit is suitable for street, towing, and race track use, providing consistent thermal management under severe operating conditions. The included galvanized bracket kit offers quick and easy installation, eliminating the need for fabrication or modifications. The pre-wired loom harness with fuse and relay features plug-in connectors for a clean, reliable electrical connection. The thermostatically controlled 80-watt, 10-inch electric fan maintains optimal operating temperatures, preventing overheating and ensuring continuous performance. With fittings, clamps, hoses, and hardware included, this kit is a comprehensive solution for high-performance cooling needs, tested to withstand pressure levels up to 300 psi. The large 5/8-inch inlet and outlet ports prevent restriction and facilitate turbulent oil flow, further improving cooling efficiency. Designed to enhance transmission durability and optimize performance, the BD Diesel cooler kit is an essential upgrade for heavy-duty trucks and fleet vehicles operating under severe conditions. Its robust construction and advanced cooling technology contribute to lower operating temperatures, increased power transfer, and extended component lifespan, ensuring your vehicle remains reliable mile after mile.
