Features, Description, Q&A
High Performance Exhaust Brake. The Pacbrake DirectMount 4-Inch PRXB High Performance Exhaust Brake Kit for onboard air significantly increases engine braking power, improving vehicle control and safety, especially on steep declines. This exhaust brake uses air actuation combined with a patented butterfly valve to provide effective backpressure, helping reduce brake wear and enhance overall driving confidence.
Construction and Appearance. The system features components coated with an industry-exclusive Arcor nitride finish, enhancing durability by providing excellent resistance to wear and corrosion. The brake housing and internal parts are engineered for severe duty applications and built to meet military specifications, ensuring long-lasting performance under harsh operating conditions.
Installation. Installation requires the vehicle to have an existing onboard air system as the kit does not include the air supply. The setup is straightforward for technicians familiar with air-actuated systems and typically does not require drilling or significant modifications.
Warranty. This product includes a manufacturer’s warranty to protect against defects and ensure customer satisfaction.
Application. Specifically designed to fit 04.5-07 5.9L RAM 2500 with Manual Transmission; 06-07 5.9L RAM 2500 with 48RE Automatic Transmission.
