The BD Diesel Brake with part number 1037136 is a heavy-duty exhaust brake designed for 1994 to 2002 Dodge Ram 2500 and 3500 trucks. This robust system provides reliable retarding horsepower up to 150 HP across the engine’s RPM range, making it an essential component for safe descending grades with trailers or heavy loads. The brake features a rugged cast-iron housing with BD’s exclusive alumibronze bushing and a positive-sealing piston ring, ensuring long-lasting leak-free operation under high-heat conditions. Its variable orifice technology allows precise regulation of back-pressure, contributing to consistent braking performance and reduced brake fade during extended downhill towing.
This exhaust brake is controlled via a convenient lighted on/off toggle switch or an optional stick-mounted rocker switch for manual transmission vehicles. It mounts most commonly in a turbo-mount configuration, replacing the factory elbow between the turbo and exhaust system, or as an inline installation between the engine and muffler or DPF. The included components, such as the brake valve, spool valve, and mounting hardware, are made from corrosion-resistant stainless steel, ensuring durability in harsh environments. For newer trucks, the system’s integrated air compressor can be utilized for additional applications like air horns, airbags, or air-ride fifth wheel hitches, demonstrating its versatility and toughness.
The BD Diesel Brake is engineered to stand up to demanding conditions, providing consistent, high-performance retarding to improve safety and reduce wear on service brakes. It includes a port to monitor retarding performance and, in most models, an EGT port for exhaust gas temperature monitoring. Proper installation and adherence to the manufacturer’s break-in procedure are critical for optimal operation. This component is suitable for fleet operators and heavy-duty enthusiasts seeking a proven solution for downhill control and extended component longevity.
