Exhaust Brake

Control heavy downhill loads, prevent dangerous brake fade, and extend the lifespan of your factory brake pads on your classic Dodge Ram with an aftermarket exhaust brake engineered for the 1989–1993 1st Gen 12V Cummins. Vintage 12-valve engines produce massive low-end pulling power, but navigating steep grades with heavy trailers can quickly overwhelm factory braking systems. Upgrading to a high-performance exhaust brake restricts exhaust flow to generate powerful backpressure, providing reliable, engine-assisted retardation that keeps your heavy loads secure and manageable on any descent.
