  • 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 the 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).
