Duramax LB7 Diesel Performance Exhaust Break

Exhaust Brake

Designed with safety in mind and built on quality, the Pacbrake Direct Mount® is a bolt on 'pays-for-itself' product that saves wear and tear on your brakes. When used consistently, this exhaust brake can extend the life of your service brakes by as much as 5 times!

The superior Directmount installs easily with no welding or special tools, and bolts on with no engine modification in most cases. The exclusive sealing system prevents exhaust gas from escaping into the engine compartment and is safe for all engine components.

Avoid costly brake jobs, escape brake fade, and gain peace of mind on the steepest descents and during everyday stop-and-go driving. Engineered specifically for your Dodge, Pacbrake's DirectMount design bolts right onto the turbo and you can install it easily with no special tools or complicated wiring. Its high temperature coating prevents harmful corrosion and because it has a back pressure preset, 90° closing valve, you'll get reliability without the risk of engine damage. With use of the exhaust brake on trucks equipped with an automatic transmission, the addition of the ATS CoPilot Lockup Controller is strongly recommended for maximum retarding power. Upgrading the torque converter to the ATS Five Star Torque Converter is recommended for maximum converter strength & effectiveness.
