Pacbrake (C44037) PRXB Exhaust Brake Kit for trucks w/on-board air (04.5-07 5.9L Cummins w/manual trans)

For models equipped with on-board air

Pacbrake’s flagship product, the PRXB (Pressure Regulated Exhaust Brake), is the unquestioned leader in the exhaust brake industry. The patented PRXB design delivers the strongest braking horsepower, greatest speed reductions and shortest stopping distances possible without the use of service brakes. It maintains optimum retarding performance by maximizing the exhaust back pressure throughout the entire RPM range. Unlike a typical exhaust brake, which requires high RPMs to work properly, the PRXB delivers constant exhaust pressure (braking) as early as 1200 RPM through to the maximum allowable RPM

Features:

• Stainless steel sealed air cylinder
• Automatic low-rpm adjustment
• Maximum allowable exhaust backpressure limit
• No overpressure potential
• 90° Closing, non-contacting butterfly valve
• Arcor Nitride housing & components
• Free flow exhaust
• Precision mounting surface

Includes:

• PRXB Exhaust Brake
• Air Accessories & Fittings Kit
