The Jacobs’ Two-stroke Engine Brake for High Power Density Engines realizes up to 1.5 times the available braking performance of a conventional compression release engine brake. This technology can apply not only to smaller displacement engines but will also maximize the performance of your current engine.


  • Two-stroke braking removes intake and exhaust from the braking event and allows for optimum airflow to maximize performance
  • Provides a high performance solution with proven technology components 
  • Minimum engine height increase
  • Low hydraulic compliance system
