Description
Maximum Braking Power and Control. The Pacbrake InLineMount 4-Inch PRXB High Performance Exhaust Brake Kit delivers unmatched braking strength for your 7.3L Powerstroke engine. By using backpressure to safely slow your vehicle without excessive use of the service brakes, it improves downhill control and extends overall brake life, perfect for towing or hauling heavy loads.
Patented PRXB Technology. Equipped with Pacbrake’s exclusive Pressure Regulated Exhaust Brake (PRXB) technology, this system maintains high braking power across a wide RPM range. Unlike traditional exhaust brakes that lose efficiency at lower speeds, the Pacbrake InLineMount 4-Inch PRXB High Performance Exhaust Brake Kit design ensures consistent braking force whether you’re cruising or descending steep grades.
Built to Last. Built from high-quality cast iron and stainless-steel components, this Pacbrake InLineMount 4-Inch PRXB High Performance Exhaust Brake Kit withstands extreme heat and pressure conditions for long-term reliability. Pacbrake’s rigorous testing ensures durability that stands up to the toughest towing environments.
Greater Safety and Reduced Brake Fade. By relieving your service brakes from constant strain during descents, the Pacbrake InLineMount 4-Inch PRXB High Performance Exhaust Brake Kit significantly reduces brake fade and heat buildup. This results in safer operation, especially when carrying heavy trailers or navigating mountain roads.
Installation. Putting this Pacbrake InLineMount 4-Inch PRXB High Performance Exhaust Brake Kit on your 7.3L Powerstroke F-250 Super Duty takes 4 hours to install.
Warranty. There is a limited warranty on this product.
Application. The Pacbrake InLineMount 4-Inch PRXB High Performance Exhaust Brake Kit fits 1999-Early 2003 7.3L Powerstroke F-250 Super Duty models with Manual Transmission.
