Description

IMPORTANT NOTICE: Requires Banks iDash tuner which is not included.

Banks Power exhaust brakes are tops in safety. Their revolutionary design produces stronger, more sustained braking force—and actually increases engine power, when not in use, by increasing airflow and diffusing exhaust. These kits utilize a computerized brake control (CBC) module that automatically senses throttle position, controls brake engagement, and eliminates annoying brake noises for improved operation and drivability. So, keep your brakes cool and ready for emergencies by cutting downhill speeds with Banks Power engine (exhaust) brakes. Order the kit recommended for your application.
