PacBrake's New Patented PRXB™ is "A Revolutionary Advancement In Exhaust Brake Technology."

In a fast paced industry, improvement and a proactive approach to demand are a must. As a leader in exhaust brake technologies, Pacbrake is proud to announce the PRXB.

PRXB™, Pacbrake's Premium Performance Exhaust Brake, provides constant backpressure as engine speed changes to maintain optimum retarding performance throughout the entire RPM range.

Its unique design will compete with both engine brakes and fixed orifice exhaust brakes.

In addition to the regular features of a traditional exhaust brake, the PRXB™ has up to 1/3 more retarding horse power at 1500 RPM. Not only does the PRXB maximize braking power for steep downhill descents, it operates quiet enough for in-city standards.

The "Extreme Braking Performance" is superior to existing exhaust brakes combined with a design able to maintain up to 3/4 the power of an engine brake. The PRXB, at 1/4 the weight and 1/2 the cost, provides an excellent alternative to an engine brake.
