Pacbrake’s new PRXB (PRemium
performance eXhaust Brake) offers a full 33 percent more retarding
horsepower than a standard exhaust brake at 1500 RPM, yet sells for half
the cost of an engine brake.
The PRXB features a constant-backpressure design that maintains optimum retarding performance throughout the engine’s entire operating range. It’s available in 3.5″, 4″ and 5″ sizes for most popular applications, and makes a great upgrade for existing exhaust brakes.
Like all Pacbrake products, it’s made to fit, and made to perform!
