Pacbrakes 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, Pacbrakes 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. ECM Bypass Kit (Optional) - Part Number #PAC C14037 (Dodge Cummins 5.9L 2003-2004) ECM Bypass Kit (Optional) Part Number #PAC C20135 (Dodge Cumming 5.9L 2004.5) ECM Bypass Kit (Optional) - Part Number #PAC C20141 (Dodge Cummins 5.9L 2005) Switch-Pac (Optional) - Part Number #PAC C18042 Note: Do not install the kit on 2003 model year Dodge trucks built up to June 27th 2005 with automatic transmissions without a transmission controller.

Yes this will work on the 1500.
100 psi
Yes! This is a bonus feature of an exhaust brake. It creates a restriction at idle that puts a slight load on the engine, causing the engine to warm up faster.
This is a normal operation if the engine is not warm. This allows the engine to warm up sooner by increasing engine load at idle. This feature can be turned off by cycling the toggle switch 8 times.
Every Pacbrake exhaust brake has a 1/8" NPT port tapped into the side of the exhaust brake housing. It has a port plug threaded into it from the factory. Remove the plug and install a back pressure gauge to this port. Go for a test drive and observe the backpressure readings.
The exhaust brake requires very little maintenance. If it is switched off the brake will go through an "exercise cycle" which activates the brake 3x at startup. This is to ensure it does not stick or seize up with inactive use. Also, it is recommended to apply a few drops of Pacbrake Super Lube to all pivot points every 3-6 months.
No, you cannot. This spring is specifically calibrated and adjusted and made tamperproof on the assembly line. This is done to ensure each application is matched to the maximum engine backpressure and will not cause any damage. Tampering with the springs will void the warranty and potentially cause severe engine damage.
This application is the preferred option for vehicles with a tight 90° bent header pipe post turbocharger. The cast adapter is constructed from cast iron with machined mating surfaces on both ends, eliminating any chance of exhaust leaks.
This is a traditional style exhaust brake tuned for maximum allowable backpressure at the maximum engine rated RPM by the drilling of a carefully selected hole size in the butterfly valve.
InLineMount – Some vehicle configurations do not allow for clearance around the turbocharger, for installation of a DirectMount exhaust brake, these applications require an InLineMount. Inline exhaust brakes require a minimum 7" of straight exhaust pipe which is then cut out and exhaust flange adapters are installed in its place. Ensure the exhaust brake is mounted as close to the turbocharger as possible and away from road spray.
NOTE: Clamped joints that exist between the brake and the engine must be welded to ensure that the joints cannot separate or leak under pressure. No flex pipe is allowed between the exhaust brake and the turbocharger.
