PacBrake PRXB Inline Exhaust Brake 07.5-18 Dodge Ram 6.7L Cummins
Description
The PRXB exhaust brake from PacBrake provides stopping power to not only save your service brakes, but keep you and your load safe on nasty descents. This kit mounts inline (as opposed to turbo mount) to an aftermarket 4 exhaust.
For those that had a 5.9L Cummins with a PacBrake exhaust brake, and then made the switch to a 6.7L with a factory VGT brake, you know all too well that the PacBrake completely outperformed the slowing power of the factory unit. Sure, the VGT works good for a factory unit, but it truly doesn't compare to a traditional, butterfly valve style of brake, such as the PRXB.
And for those that have upgraded turbo to a non-VGT style of turbo, such as an S300, you've now completely eliminated any exhaust brake. If you're ready to get a brake back, and have something that's performance completely overshadows that of the stock exhaust brake, you need to upgrade with this replacement from PacBrake.
VEHICLE REQUIREMENTS:
4" or 5" Turbo Back Exhaust
Non-VGT (Variable Geometry Turbo)
WHAT IS A PRXB? A PRXB is a Pressure Regulated Exhaust Brake that offers the highest retarding power for the lowest price available. Although the PRXB's retarding power is comparable to that of a compression release engine brake, the manufacturing and installation costs are significantly less.
HOW IS IT DIFFERENT FROM A STANDARD FIXED ORIFICE EXHAUST BRAKE? Conventional exhaust brakes experience a reduced exhaust backpressure at low engine speeds, resulting in an unnecessary loss of braking power. Pacbrake's innovative PRXB addresses this issue with a patented wastegate design that regulates exhaust backpressure as engine speed changes. The valve maintains near constant engine backpressure throughout the entire RPM range, providing maximum exhaust braking power at all times.
Controlled by a master ON/OFF switch, Pacbrake's exhaust brakes provide whisper quiet supplemental braking that allows service brakes to be used much less, ultimately saving 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.

About PacBrake
PACBRAKE EXHAUST BRAKES
Pacbrake is a manufacturing company based out of Langley, British Columbia that began operations in 1961, specializing in exhaust and engine brakes for commercial truckers, loggers, and the military. Today, their expertise still lies on exhaust braking solutions, but it goes well beyond this and into numerous other vehicle upgrades such as air suspension, air compressors, complete air management solutions, and so much more.
PACBRAKE EXHAUST BRAKESDiesel Power Products is proud to offer the complete line of Pacbrake PRXB Exhaust Brakes for Cummins, Duramax and Powerstroke diesels. At the time of their release, the PRXB line of brakes was unlike any other, and still maintains superiority over many alternatives to this day. So what does PRXB mean and how does it work? PRXB stands for "Pressure Release Exhaust Brake." Basically, all exhaust brakes have to release a certain amount of exhaust, otherwise it would cause excessive backpressure to the engine and cause damage. However, PRXB's are unique in that they have a variable release so that as RPM's slow down, so does the release of exhaust, equating to better retarding power at lower RPM's. If you tow with your diesel and don't have an exhaust brake, you're simply missing out on the peace of mind and safety that it delivers. Pacbrake's kits come complete, even torque converter lockup controllers when applicable, exhaust adapters for aftermarket oversized exhaust, and more.
