The BD Diesel Brake (Part # 1027146AP) is a heavy-duty exhaust brake engineered specifically for 2003-2007 Ford F-250 Super Duty trucks equipped with the 6.0L PowerStroke engine and automatic transmissions. This exhaust brake is designed to enhance vehicle control and safety during descents on steep grades by providing up to 150 horsepower of retarding power throughout the engine’s RPM range. Its rugged cast-iron housing ensures durability under the high-heat conditions typical of diesel exhaust environments, making it a reliable component for fleet operators and heavy-duty applications. The unit features BD’s exclusive variable orifice technology combined with spring-loaded cylinder pressure regulation, which optimizes braking performance while minimizing wear and tear on the engine and drivetrain.
Installation is straightforward with mounting hardware made of corrosion-resistant stainless steel, and the system includes an air compressor that can also be utilized for other pneumatic accessories such as air horns or air-ride components. The brake communicates seamlessly with the engine’s electronic idle verification system, allowing for quick engagement via a toggle or optional stick-mounted rocker switch. Most applications mount directly in place of the factory elbow between the turbo and exhaust system, providing a clean, integrated look and optimal performance. Optional programmable AutoLoc and PressureLoc kits are available for automatic control of the torque converter clutch in trucks built before 2006, further reducing slippage and transmission temperatures for improved longevity.
This exhaust brake comes complete with all necessary hardware, wiring, and instructions, making it suitable for fleet operators seeking a dependable, high-performance retarding solution. With its proven performance and industry-leading durability, the BD Diesel Brake is widely recognized as the most effective diesel exhaust brake in the market, ensuring safer descents, reduced brake wear, and lower operating costs for heavy-duty diesel trucks.
