BD Diesel 2023138 Exhaust Brake Air Actuated Turbo Mount Dodge - for 2003-2004 5.9L

The BD Diesel 2023138 is a turbo-mounted exhaust brake designed specifically for 2003-2004 Dodge trucks equipped with the 5.9L Cummins diesel engine. This air-actuated system provides superior engine braking performance to help control your vehicle on steep grades and during heavy towing.

Variable Orifice Technology:

BD Diesel's exclusive Variable Orifice Technology uses a solid, offset butterfly valve with spring-loaded cylinder and pressure regulation to deliver up to 150 retarding horsepower consistently throughout the engine's RPM range—not just at high RPM like competing designs. This provides smooth, predictable braking power when you need it most.

Built for Durability:

• Rugged cast-iron housing engineered to withstand extreme exhaust temperatures
• Stainless steel butterfly valve and shaft resist corrosion and wear
• Exclusive alumibronze bushing and piston ring seals for long-term reliability
• Corrosion-resistant stainless steel mounting hardware included
• Air compressor included in kit for pneumatic actuation

Installation and Warranty:

Estimated installation time is 4 hours. BD Diesel backs this exhaust brake with a 24-month/24,000-mile parts warranty and 12-month/12,000-mile labor warranty.

Important Notes:

• Not legal for sale or use on California-licensed vehicles
• Trucks with aftermarket turbos (except BD Killer B 1045161) require remote-mount exhaust brake
• Automatic transmission vehicles should consider adding an AutoLoc or lower stall converter for optimal performance
• Exhaust back pressure test gauge kit (BD 1030050) recommended for proper setup

This product meets EPA reasonable basis requirements and is legal for sale and use within federal EPA jurisdiction (EMS:2).
