The Pacbrake C40111 PRXB exhaust brake offers superior braking power and durability for 2004.5-2007 Dodge RAM 2500/3500 trucks with the 5.9L Cummins ISB 24 Valve engine. This direct-mount, 4-inch exhaust brake provides 50% more braking power in the critical 1400-1800 RPM range. Its patented 90-degree non-contacting butterfly valve is engineered to maximize backpressure while preventing seizing, and a spring-controlled pressure-regulated mechanism protects against engine overpressure. The unit features an industry-exclusive Arcor nitride coating on housing and components for enhanced wear and corrosion resistance, and increased lubricity. This upgrade kit is designed to replace a fixed orifice exhaust brake. It is compatible with both standard and 48RE automatic transmissions.
