Jake vs Exhaust Brake

[Trixie47]

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

I have a 2007 3500 with 5.9L Cummins --- tow a 14K 5th wheel
Have an 'exhaust brake'====4" electric solenoid actuated butterfly with a 2" spring loaded bypass butterfly that controls backpressure

GCVWR 22,000 (truck/trailer)....6% grade exhaust brake will hold downhill speed at 50 mph

BEST add on device I have done!!!!

^ LMMs are not recommended to use a conventional inline butterfly valve exhaust brake. (Guessing other VVT diesels have a similar recommendation)
Not saying it wouldn't work, but everything I've seen in the past says no inline butterfly valve brakes with the emissions systems intact.
Either way, a $600 plug n play module like ib516 mentioned gets you a turbo brake without even getting your hands dirty or busting out a wrench!

You will find an actual exhaust brake (valve that goes in the exhaust and creates back pressure) for about $1000 and one that uses a computer box to close down your factory turbo like the new ones do for about $500.

Check out BD Diesel and Banks as two examples of the above.

A "Jake brake" is technically an engine brake, which opens the exhaust valve during TDC to purge the compressed air. It turns your engine into a giant air compressor.

Jacobs as a company also make exhaust brakes, which operate similar to the variable geometry turbo induced braking on OEM setups.

With light duty trucks, you only have one choice - exhaust. An engine brake is better, the best can produce almost as much retarding hp as the engine hp rating.

What most refer to as a Jake Brake is an engine brake that alters valve timing, the only one I have seen offered for HD pickups is from PacBrake for the Cummins engine.

Jake, but it is more expensive and I doubt they make one for your engine as Ivylog stated. You might have to go the exhaust brake route
