2004.5-2005 Cummins Exhaust Brake (55227)

Fits

The Banks direct-mount, no-maintenance exhaust brake has electronics that monitor critical engine and transmission parameters to maximize braking efficiency to keep your Cummins on the road with control and safeguards. It dramatically cuts downhill speeds without using the wheel brakes. This keeps brakes cool and ready for emergencies and saves thousands in brake maintenance. Optimizes exhaust flow when not engaged. Easy install, needs no drilling, cutting or modifications to stock wiring. Fast warm-up function prolongs brake durability, and automated brake disengagement at low speed smoothes stop-and-go driving. Smooth, controlled downhill descents. Highest peak braking horsepower. Immediate response. Superior airflow with brake open. By far, the quickest braking response time, the vacuum pump produces no audible noise over normal engine sound.
