MX-11 Engine Brake

Jacobs Vehicle Systems has launched an engine brake for the PACCAR MX-11. 

The result of more than three years of collaboration between Jacobs and PACCAR engineers to minimize weight and space the new engine brake is said to  deliver as much as 427 hp of braking power at 2100 rpm and 278 hp at 1500 rpm, which is the most fuel-efficient engine speed. 

The MX-11 brake is currently available in the European market on the new DAF Euro 6 CF and XF Series trucks and will be launched in North America on Kenworth and Peterbilt trucks in January 2016.
