Description
High Performance Exhaust Brake. The Pacbrake DirectMount 4-Inch PRXB High Performance Exhaust Brake Kit delivers exceptional retarding power for heavy-duty applications, improving vehicle safety and control by providing increased braking force without relying solely on service brakes. It is ideal for managing long downhill descents and heavy towing loads.
Construction and Appearance. Built with durable materials featuring an exclusive Arcor nitride coating, the exhaust brake housing and components resist wear and corrosion while enhancing lubricity. The patented butterfly valve design ensures reliable long-term operation under severe duty conditions. The finish prioritizes functional performance.
Installation. Installation requires mechanical proficiency to ensure proper integration of the air-actuated system and valve mounting. The kit includes all necessary components such as the air tank, hoses, and accessories. Installation specifics may vary based on vehicle configuration.
Warranty. The product comes with a supplier-specified limited warranty. A 60-day money-back guarantee may be available as outlined by the supplier's return policy.
Application. Designed specifically for Dodge RAM and Cummins 5.9L 24-Valve Engine models from 2004.5 through 2007 with standard transmission, and 2006-2007 models equipped with the 48RE automatic transmission. This exhaust brake will not function with the Banks Turbo Back Monster Exhaust but is compatible with the Banks Cat Back Monster Exhaust. It is not available for sale in California due to regulatory restrictions.
