The BD Diesel Brake (Part # 2023138) is a heavy-duty exhaust brake designed specifically for 2003-2004 Dodge Ram 2500 and 3500 trucks equipped with turbocharged engines. Constructed with rugged cast-iron housing and BD’s exclusive Alumibronze bushing, this brake offers reliable performance in high-temperature exhaust environments. It features a variable orifice technology that provides up to 150 horsepower of retarding force across the engine’s RPM range, making it an essential component for descending grades with trailers or in severe towing conditions. The unit is mounted most commonly in the turbo elbow or inline within the exhaust system, ensuring a seamless fit that maintains optimal engine performance and safety.
The BD Diesel Brake is controlled via a lighted On/Off toggle switch or an optional stick-mounted rocker switch for manual transmissions, and it communicates with the engine’s electronic idle verification system for rapid engagement. Its durable design includes stainless steel butterfly shafts, corrosion-resistant mounting hardware, and a spring-loaded cylinder that ensures consistent brake operation. Most kits include an air compressor, which can also be used for additional air-powered accessories such as air horns, air bags, or air-ride fifth wheel hitches, emphasizing its versatility and robustness. When installed correctly, this exhaust brake significantly reduces brake fade during downhill driving, improves vehicle safety, and increases component longevity.
This exhaust brake is suitable for trucks that require high-performance retarding power, especially in demanding fleet or towing applications. The unit’s proven ability to withstand harsh heat and exhaust conditions makes it a preferred choice among fleet operators and heavy-duty enthusiasts. It is important to verify compatibility with your specific vehicle and engine setup before installation to ensure optimal performance and safety. Regular maintenance, including inspection of mounting hardware and sealing components, will help sustain its reliable operation over time.
