according to Jake Brake's website, i think the L10 is the smallest cummins offered with a Jake, HOWEVER.............. the 7.2 Cat they put in F-650 Ford trucks you can get one for.

Might as well set your truck up to run an 8.3...they have jakes don't they? That's gonna take one big cowl hood too.

NOPE......they are just a fat 5.9......

That's what I was thinking....wasn't sure.

Well I e-mailed PacBrake's tech department about the comment Rattler made. I'll let yall know what they tell me. I don't think these companies realize how many they would sale if they actually would make one.

Yeah, but the R&D would far outweigh the sales profits. First comes designs, prototypes, testing, redesigns, retesting (this can go on for months, often years before a final production version is reached). Then comes the big expense, TOOLING. Figure a few million dollars, then production costs for overhead, material cost, labor cost, and warranty work.

All for a product that does nothing better than a standard exhaust brake, it just sounds cool. Even if Pacbrake ends up producing one, do you know what the cost will be just for the part? I bet at least $3,500, and probably closer to the $5k mark. Remember, they don't just bolt on, there are a lot of other necessary parts, gaskets, and adapters to install a Jake.

Yea, you'll need a whole new head at the least.

Don't tell him all that. He'll just think you're being a smartass.

the problem is the engine isnt strong enough, when a jake engages it holds the exhaust valve open, and that would rattle apart the smaller 5.9.

I think this might be one thing our beloved 5.9 might not be able to handle.:booo:

but i do think it would be a sweet thing to have.:choochoo:

The block and head could handle it, but you'd surely need studs, and a ton of machining to the head, if not a whole new casting...

Why don't you just ask somebody to invent something that sticks in your exhaust pipe and makes the jake noise when you flip a switch. They have those whistlers you stick in your muffler to make it sound like you have a turbo... It'd be way cheaper than trying to fit a real jake. lol

i know this is an old thread, but i was wondering if anyone would be interested in a set of jakes for the 12 valve cummins, i have a set of jakes off of a cummins 350 small cam, and i am going to try machining valve covers to hold the electronic actuators for a set of jakes.
