PRXB Exhaust Brake Kit – C44031 – DirectMount 4 Inch Exhaust (Air Actuated)

• 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).
  
  
• The spring controlled pressure regulated mechanism on the exhaust brakes protects against engine overpressure.
  
  
• 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 maximise 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.

Every PRXB Automotive Kit comes with everything required for a complete installation. PRXB Exhaust Brake, Controller (when required for application) and Pacbrake Onboard Air Kit.
