Jake vs Exhaust Brake
Pulling a 2012 39 ft. 5th wheel with a 2008 Chevy Silverado 3500 dwd. Question is: what is best ? Jake brake or Exhaust brake ?

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 Jake to which (IMO) aren't as good. A true Jake requires the engine to be between 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.
Not so, PacBrake makes an engine brake for the Cummins 6.7 that is a bolt on kit. Looks like it raises the valve cover about 1-1/2”.
The PacBrake exhaust brake is not a compression release brake such as a "Jake Brake". It is a little more effective than a standard exhaust brake but both the PacBrake and a standard exhaust brake utilize the turbo vanes to create back pressure in the exhaust system to provide the engine braking. The engine brakes on the bigger diesels are far more effective. A pick up truck doesn't really have need for the level of braking provided by a "Jake".
