Description

Product Description

  • 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 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.
