COMING SOON: Jacobs Vehicle Systems is now part of the Cummins family, and our website will be merging with Cummins.com soon. When this happens, our pages will have a new look, but don’t worry, you will still be able to use our parts and service pages for all of your Jake Brake needs.
From Spec Sheets to Tune-up Kit Instructions, Service Letters to Installation Manuals, our Service Literature look-up has the literature you need for your engine brake. For product-related and technical inquiries related to the engine brake, please contact your engine manufacturer’s parts and service network.
Narrow your results by selecting an Engine Manufacturer and/or type of literature. You can also narrow the results by engine model numbers and/or Jacobs brake model numbers. Full or partial searches will work.
