PacBrake C40119 PRXB Pressure Regulated Exhaust Brake for CAT 3116 and 3126 Inline Exhaust Applications
PacBrake’s flagship product, the PRXB (pressure regulated exhaust brake), is the unquestioned leader in the supplemental brake industry. The patented PRXB design delivers the strongest braking horsepower, greatest speed reductions and shortest stopping distances possible without the use of service brakes. It maintains optimum retarding performance by maximizing the exhaust backpressure throughout the entire RPM range. Unlike a typical exhaust brake, which requires high RPMs to work properly, the PRXB delivers constant exhaust pressure (braking) as early as 1200 RPM through to the maximum allowable RPM.
Controlled by a master ON/OFF switch, you can choose when to engage the exhaust brake with just the lift of your foot from the throttle pedal. PacBrake’s exhaust brakes provide whisper quiet supplemental braking that allows service brakes to be used much less, ultimately saving you money. They have the ability to be left on all the time, making it ideal for in-city driving or for steep, downhill grades. This product pays for itself as less wear on the brake pads means fewer brake jobs.
Product Benefits:
- Provides 50 percent More Braking Power at Lower RPM's. PRXB gives you the best hold-back in the 1400-1800 RPM range (where you typically drive).
- The spring controlled pressure regulated mechanism on the exhaust brakes protects against engine over-pressure.
- 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 back-pressure 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.
Applications:
- Motorhome and trucks with Cat 3116 / 3126 with 4" Exhaust - Inline Universal
Special Notes:
- Inline exhaust installation - Does not mount to back of turbo.
