The PXRB C44067 Inline 4" PXRB Exhaust Brake Kit will deliver the strongest braking horsepower, greatest speed reductions, and the shortest stopping distances possible without the use of your service brakes. Not only will this kit protect your engine from the potential of overpressure, but it will also maintain optimum retarding performance by maximizing the exhaust backpressure throughout the entire operating RPM range. If you are wanting an unmatched exhaust brake that will provide increased performance, safety, and durability, then the PXRB is the brake for you. 

Part Number: C44067

• Provides 50 percent More Braking Power at Lower RPM's PRXB gives you the Best holdback in the 1400-1800 RPM range (where you typically drive). Better than any standard exhaust brake on the market.
• 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 a 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).
