Would take a heck of a lot of modding to stuff a engine that uses a Jake brake in a pick up. If I'm not mistaken, I think Cummins invented the Jake Brake and granted it's use for all semi engines but some mfr's may offer their own version of a Jakeibetween 1600-2000 to get the best retarding power. Exhaust brakes offered by Ford, GM & Ram are better than nothing and from what I gather, folks seem to be quite happy w/ them.

Clessie Cummins, one of the founders of what became Cummins engine is credited with the invention of the jake brake in the late 50's. It was granted a patent in the early 60's. I think by that time he was not associated with Cummins and when he went looking for someone to market it, Jacobs mfg was the only taker, which, relates to how it got it's name, Jake brake. Jacobs started mfg it in about 1961 IIRC. BTW it's the same Jacobs that makes 3 jaw drill chucks.
