This exhaust brake is to be mounted directly to the factory turbo, or with an aftermarket turbo with the same outlet flange as the factory.

Diesel engines, unlike gasoline engines, don't slow down simply by taking your foot off the accelerator; they rely on service and supplemental brakes. An exhaust brake is a form of a supplemental brake, and they work much differently than their conventional counterparts.

Introducing the Pacbrake PRXB
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, 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.

In order to have consistent and effective braking over the entire RPM range, it is important (and necessary) to maintain constant backpressure. To achieve this, Pacbrake's patented design has incorporated an additional waste gate on the butterfly valve to regulate the amount of exhaust flow that is being passed through. The flow is controlled by a spring-loaded arm, whose pressure rating and location are key factors in the functionality of the PRXB. Located outside of the housing and away from the heat, the spring is able to maintain its strength and durability for years of proper and precise braking performance.

PRXB Exhaust Brakes: PRXB To The Test
Two trucks, one equipped with a PRXB exhaust brake and the other with our competitors exhaust brake, are traveling down a 5% grade. Both vehicles start descending at the same time while traveling at a speed of 45 MPH. With a sharp corner ahead, both vehicles activate their exhaust brake...

RESULTS AFTER 60 SECONDS
The truck equipped with the PRXB slowed to a safe cornering speed (18 MPH) in just under 1/2 mile. In that same amount of time, the truck equipped with our competitors exhaust brake traveled 450 ft MORE and was still moving at a dangerous 30 MPH. Did this truck slow down in time?

IMPORTANT NOTES:
  • If you have added an aftermarket 4" exhaust, you will need (1) additional exhaust adapter (C11342).
  • Kits for automatic transmission trucks include a torque converter lockup controller.
  • All three kits come with heavy duty 60 psi exhaust valve springs.
  • This exhaust brake is to be mounted directly to the factory turbo, or with an aftermarket turbo with the same outlet flange as the factory.

A Cable That Knows Its Job and Does It Without Drama
Style: 1-Pack, Size: 6 Feet
This Amazon Basics DisplayPort‑to‑HDMI cable is the strong, silent type — uni‑directional, dependable, and absolutely not here for your “why won’t this work backwards?” nonsense. It plugs in, does its job, and beams your DisplayPort signal to your HDMI display like a loyal little digital courier. No flickering, no tantrums, no “surprise, I’m actually an adapter from 2009.” If you want a cable that just works and doesn’t demand emotional support, this is the one.

Clear picture and reliable connection.
Style: 1-Pack, Size: 6 Feet
This DisplayPort to HDMI cable was exactly what I needed at a low price point to connect my computer to my monitor. The gold-plated connectors are functional for maintaining a steady signal, and the 6ft length is more than adequate for my desk setup. I’m giving it 5 stars because the picture quality is excellent and it worked immediately without any flickering—this was a good choice.

just works perfectly out of the box
Style: 1-Pack, Size: 6 Feet
Plugged this in between my PC and monitor and it worked right away with zero setup required. Picture quality is great and I've had no issues with flickering or signal drops after weeks of use. The 6 foot length is perfect for a typical desk setup and it feels a lot sturdier than the random cheap cables I've used before. Honestly what more could you want from a cable at this price point.
