The BD Diesel Brake (Part # 1037135) is a heavy-duty exhaust brake designed for use on Dodge trucks from 1989 to 1998, including D250 and D350 models. This exhaust brake features a vacuum operation with a 60 PSI control system, providing reliable retarding power to enhance vehicle safety and control on descending grades or challenging terrains. Its rugged cast-iron housing incorporates BD’s exclusive alumibronze bushing and positive-sealing piston rings, ensuring long-lasting, leak-free performance even under high-heat conditions. The system is controlled via an included brake valve and spool valve, with mounting hardware made of corrosion-resistant stainless steel for durability in demanding environments. The kit also features a port to monitor retarding performance and is compatible with most trailer and engine brake applications.
The BD Diesel Brake communicates seamlessly with the engine’s electronic idle verification system, enabling quick engagement via a lighted On/Off toggle or optional stick-mounted rocker switch for manual transmissions. Most applications mount directly in place of the factory exhaust elbow or inline within the exhaust system between the engine and muffler or DPF. The included air compressor, standard in most kits, can also be used for auxiliary functions such as air horns, air bags, or air-ride fifth wheel hitches, emphasizing the component’s rugged versatility. Proven to withstand harsh exhaust environments, this brake provides up to 150 retarding horsepower across the engine’s RPM range, significantly improving downhill control and brake life.
Designed for heavy-duty fleet and automotive use, the BD Diesel Brake offers a reliable, high-performance solution for vehicles requiring precise exhaust braking capability. Its advanced features include BD’s exclusive variable orifice technology, spring-loaded cylinder pressure regulation, and a stainless steel butterfly shaft for smooth operation. With robust construction and proven durability, this brake enhances safety and reduces wear on service brakes, making it an essential component for fleet operators and heavy-duty vehicle owners.
