Direct Mount 4 inch PRXB High Performance Exhaust Brake Kit with Max Flow Design

Features:

• 50 percent More Braking Power at Lower RPM's
• Maximises backpressure while preventing seizing
• Protects against engine overpressure
• Severe duty & military approved
• Strongest braking horsepower, greatest speed reductions & shortest stopping distances possible without the use of service brakes

Pacbrake's Direct Mount 4 inch PRXB High Performance Exhaust Brake Kit W/Max Flow Design offers high performance tailored to the 5.9L Cummins, ensuring optimal reliability and functionality. One standout feature is the PRXB system, which delivers 50 percent more braking power at lower RPMs, offering superior holdback in the 1400-1800 RPM range where most driving occurs. This performance surpasses that of any standard exhaust brake available on the market. Additionally, the exhaust brakes are engineered with a patented 90-degree non-contacting butterfly valve, designed to maximize backpressure while preventing seizing. This innovative design, combined with precision machined surfaces, eliminates the need for troublesome gaskets, reducing the risk of leakage.

The exhaust brakes incorporate a spring-controlled, pressure-regulated mechanism that safeguards against engine overpressure, ensuring the system's longevity and safety. The use of industry-exclusive Arcor nitride coating on housing and components enhances resistance to wear and corrosion, while simultaneously strengthening the exhaust brake and adding lubricity. The brakes are constructed with a hard-anodized aluminum and stainless-steel body and shaft, complemented by high-performance seals for durability. Maintenance for these brakes is straightforward, requiring regular use and occasional application of Superlube, Pacbrake's multi-purpose heat-resistant lubricant, which aids in preventing rust and corrosion. When the brake is deactivated, exhaust flow remains unrestricted, ensuring it doesn't interfere with power output.
