Banks Brake w/CBC-SmartLock: Dodge 5.9L. Auto. A total system solution with enhanced transmission control for exhaust braking, Banks' direct-mount, no-maintenance exhaust brake has electronics that monitor critical engine and transmission parameters to maximize braking efficiency. 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. Computerized Brake Controller and SmartLock (CBC). Computerized brake control (CBC) and SmartLock are included. CBC automatically senses throttle position, controls brake engagement and cuts out annoying brake noises. Fast warm-up function prolongs brake durability, and automated brake disengagement at low speed smoothes stop-and-go driving. Banks SmartLock locks the torque converter & raises line pressure to smoothly reduce vehicle speed and safeguard the transmission.
