Vehicle Application



Pacbrake P55003 P-67 LoadLeash Engine Brake Kit


The Pacbrake P55003 P-67 LoadLeash Engine Brake Kit changes the diesel engine to be more like an air compressor. This supplemental brake turns the diesel engine into an air compressor, allowing it to absord more of the braking power needed for heavy-duty vehicle. Tire wear is lower since it prevents tire hop and lockup. It gives the driver better control of the vehicle when driving on elevated roads, and uses less power when descending. The engine brake has three levels of retarding power, and the whole thing uses just a single housing to make installing it easier.
