Thumbnail Filmstrip of 5.9 Cummins Direct Mount PRXB Exhaust Brake Pacbrake C44045 Images
Prepare to revolutionize your driving experience with the Pacbrake C44045 DirectMount PRXB Exhaust Brake, specifically engineered for 2004.5-2007 5.9 Cummins manual transmissions and 2006-2007 automatic transmissions. This isn't just an accessory; it's an indispensable upgrade that elevates your control, enhances safety, and significantly extends the life of your service brakes. The PRXB, Pacbrake's flagship product and the undisputed leader in supplemental braking, delivers unparalleled stopping power. Its patented design ensures the strongest braking horsepower, maximizes speed reductions, and achieves the shortest stopping distances possible—all without relying on your service brakes. Forget typical exhaust brakes that demand high RPMs to perform; the PRXB maintains optimal retarding performance by maximizing exhaust back pressure across the entire RPM range, providing constant braking as early as 1200 RPM and protecting your engine from overpressure with its spring-controlled mechanism. This means an impressive 50% more braking power at lower RPMs and superior hold-back in the crucial 1400-1800 RPM range where you do most of your driving.
- Exceptional Braking Power: Provides 50% more braking power at lower RPMs, ensuring superior hold-back in the 1400-1800 RPM range, and delivering the strongest braking horsepower, greatest speed reductions, and shortest stopping distances.
- Engine Protection: The spring-controlled pressure regulated mechanism safeguards against engine overpressure, offering peace of mind.
- Unrestricted Power Output: When deactivated, exhaust flow is unrestricted, preventing any interference with your engine's power output.
- Advanced Valve Design: Features a patented 90-degree non-contacting butterfly valve, specially engineered to maximize back pressure while completely eliminating seizing.
- Superior Durability: Housing and components boast an industry-exclusive Arcor Nitride coating, dramatically increasing resistance to wear and corrosion, strengthening the exhaust brake, and adding lubricity.
- Whisper-Quiet Operation: Enjoy supplemental braking that's barely noticeable, allowing for significantly less reliance on your service brakes.
- Cost-Saving & Convenient: Reduces wear and tear on your service brakes, translating to fewer brake jobs and substantial long-term savings. It can be left on all the time, making it ideal for city driving or navigating steep downhill grades.
- Built for Toughness: Severe Duty and Military Approved, ensuring reliability in the most demanding conditions.
- For Use On Stock Turbocharger: Seamless integration with your existing setup.
What truly sets the PRXB apart is its patented design for creating and maintaining consistent backpressure across the entire RPM range. Unlike conventional systems, the PRXB incorporates an additional wastegate on the butterfly valve, precisely regulating exhaust flow. This flow is meticulously controlled by a spring-loaded arm, strategically located outside the housing and away from heat, ensuring its strength and durability for years of precise braking performance. As engine RPMs increase, the spring compresses, allowing more exhaust flow to pass. Conversely, as RPMs decrease, the spring releases, applying pressure to the plate and restricting exhaust flow, thereby maintaining optimal backpressure and providing premium braking performance exactly when you need it. Backed by a 3-year/100,000-mile manufacturer warranty, the Pacbrake C44045 PRXB Exhaust Brake isn't just an upgrade; it's an investment in safety, performance, and the longevity of your vehicle.
Application Notes:
- All 2004 - 2007 kits will NOT work with Banks Turbo Back Monster Exhaust. However they will work with Banks Cat Back Monster Exhaust.
- Air Actuated - Comes with Air Tank, Hose and Accessories.
