What Does a 100% Increase in Engine Braking Performance Feel Like?

Jacobs High Power Density (HPD) technology generates twice the engine braking power at cruise RPM, and provides you the lightest, most cost-effective, high power vehicle retarding technology available.


  • World-class engine braking power
  • Operates at the engine speeds you use and avoids downshifting during retarding
  • Increased driver confidence and comfort
  • Faster trip times and increased productivity
  • Quicker shifting for better acceleration
  • Compensates for decreased aerodynamic drag and decreased rolling resistance
  • Improved service brake life
  • Compensates for the trend toward lower engine speed operation and specification of smaller displacement engines
