BD Diesel 2023331 Exhaust Brake Air Actuated Turbo Mount Dodge - 2004.5-2005 5.9L

The BD Diesel Performance exhaust brake provides professional-grade engine braking for 2004.5-2005 Dodge trucks equipped with the 5.9L Cummins diesel engine (325hp rating). This air-actuated, turbo-mounted system delivers up to 150 retarding horsepower throughout the engine's RPM range, giving you superior downhill control and reducing wear on your service brakes.

Variable Orifice Technology:

BD Diesel's exclusive Variable Orifice Technology uses a solid, offset butterfly design with a spring-loaded cylinder and pressure regulation to maintain consistent braking power across the entire RPM range—not just at high RPM like competitive designs. This proven system has been refined over nearly three decades of real-world testing on mountain roads and steep grades.

Built for Extreme Conditions:

• Rugged cast-iron housing designed specifically for Dodge applications
• Stainless steel butterfly valve and rotating shaft resist corrosion
• Exclusive alumibronze bushing and piston ring seals
• Stainless steel mounting hardware throughout
• Engineered to withstand the harsh, high-heat exhaust environment

Complete Kit Includes:

• Air compressor for pneumatic actuation
• All necessary mounting hardware
• Installation hardware made from corrosion-resistant stainless steel

Installation & Warranty:

Typical installation time is approximately 3 hours. BD Diesel backs this exhaust brake with a 24-month/24,000-mile parts warranty and 12-month/12,000-mile labor warranty.
