Fits

The PXRB C40075 Inline 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: C40075

• Spring controlled pressure regulated mechanism on the exhaust brake protects against engine overpressure 
• Designed specifically for individual engine applications to maximize performance & reliability (not a one size fits all compromise)
• When deactivated, exhaust flow is unrestricted and won't interfere with the power output
• Patented 90-degree Non-contacting Butterfly Valve is specially engineered to maximize backpressure while preventing seizing
  
• Utilizes Arcor nitride coating on housing & components which increases resistance to wear & corrosion while strengthening the exhaust brake & adding lubricity
• Precision machined surfaces on the exhaust brake eliminate the need for troublesome gaskets and risk of leakage
  
• Features 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)
