Description

High Performance Exhaust Brake. The Pacbrake DirectMount 4-Inch PRXB High Performance Exhaust Brake Kit for OnBoard Air is designed to significantly increase engine braking power, improving vehicle control and safety, especially on steep declines. This exhaust brake utilizes air actuation combined with a patented butterfly valve to provide effective backpressure, helping reduce brake wear and enhance overall driving confidence.
