The Pacbrake PRXB Exhaust Brake offers the highest braking power-to-price ratio.

It features a patented 90-degree non-contacting butterfly valve for maximum backpressure and seizure prevention, and Arcor nitride coating enhances wear, corrosion resistance, strength, and lubricity. The kit includes the PRXB Exhaust Brake, a controller, a Pacbrake Onboard Air Kit (HP325 Series Compressor, 0.5 Gal Air Tank, 25 Ft Coiled Air Hose, Air Accessories, and Fittings), and Heavy Duty Exhaust Valve Springs. A Transmission Controller is also included.
