2004.5-2007 Cummins Directmount PRXB Exhaust Brake (C40111)

Fits

PRXB offers the highest braking power to the lowest price ratio available for your 5.9L Cummins. Pacbrake’s flagship product is the unquestioned leader in the supplemental brake industry. Pacbrake has changed the way people think about exhaust brakes by providing performance, safety and durability that is unmatched by any other exhaust brake on the market.

This is an exhaust brake only. Can be used as an upgrade to your current fixed orifice brake. If you have no exhaust brake, you will need additional components for installation.

Part Number: C40111

• The spring controlled pressure regulated mechanism on the exhaust brakes protects against engine overpressure
• Pacbrake exhaust brakes are designed specifically for individual engine applications to maximize performance and reliability. They are not a one size fits all compromise
• When the brake is deactivated, exhaust flow is unrestricted and won't interfere with power output Patented 90-degree Non-contacting Butterfly Valve is specially engineered to maximize backpressure while preventing seizing
• The brakes use industry exclusive Arcor nitride coating on housing and components which increases resistance to wear and corrosion while strengthening the exhaust brake and adding lubricity
• Precision machined surfaces on the exhaust brake eliminate the need for troublesome gaskets and risk of leakage
• The brakes have hard-anodized aluminum and stainless steel body and shaft with high-performance seals
• Maintenance is as simple as using the exhaust brake on a regular basis and periodically applying Superlube (Pacbrake's multi-purpose heat resistant lubricant which helps to prevent rust and corrosion)
• Withstands extremely high exhaust temperatures
• Compliant with the latest emission regulations
• Severe duty & military approved
