It seems my local dealership is VERY proud of this product @ 1500.00 + installation...WOW!!

So, I'm asking fellow RV'ers. Is there better prices out there? If so, Please point me in the right direction....

Thanks......

Mr Traveler

You don't need a compression brake system for pulling this set up, if you was doing heavy haul I would think about it. I pull RV's for a living and never had a need for one

I find mine awfully handy...

Anyhow, you might price check other dealers, and your local Cummins parts house.

Also, if you are at all mechanically inclined, they aren't too tough to install yourself, though it takes several hours.

You can download a PDF of the installation instructions from Jacob's site, to help you decide if it's something you want to tackle yourself.

I bought mine on ebay from a Dodge Dealership for my 2005 and paid $700 for it.

your local diesel shops will have it cheaper if you need it installed for you

i disagree about not needing it, no maybe you don't absolutely need it but it would be a nice option

mine will have one soon also

Well if you never had one how would you know if you need one? Just the savings on the foundation wear is enough to pay for the exhaust brake. The fact you can use it at long idle times and warm up is even more benificial. Check out this link for a price and probably a better product.

Never said I never had one, I drove big trucks for over twenty year most had engine compression brakes, Seem everyone didn't not read the post I made I stated with the setup he has you don't need a compression brake. There is not enough weight that the truck can't handle it. I pull trailer of all size and weights, the choice is yours to make I don't need one.

Mopar4Less has them for $1200. 800-748-2139. When you call them be sure to ask for internet sales.

Get in from a cummins dealer and install yourself. My friend just got one for less than 700.00 and we installed it. He loves it and if I didn't have an auto, I would have one for sure.

I sure love my Jacobs and wouldn't tow much at all without one - - in fact I use it some when running solo. It is $1300 at my dealer installed.

I want to get one as well. What do you think of the ones that mount under the truck, and not at the turbo?

P.J

Can someone explain what kind of slowing power it has?
Like as in, unloaded, will it just about bring you to a stop in 50 yards or something?
Just wondering.

PJ,

Here's an example that might help you regarding mine. There is a very steep hill near here that I drive pretty often. It's about a mile long. If I start at the top at 55 mph, with the brake off, I am at 65 mph about 1/8 mile down the hill. If I turn the brake on, I go down the entire hill at 45 mph. That is in 6th gear turning about 1500 rpms. If I downshifted to 5th, I would probably stay at 35 mph. The higher your rpms the better the brake works. I drove all the way home today without just to see if I could tell a difference without it on. The difference is unbelievable. To me it's worth every penny.

Hello
This is not a "real Jacoabs" brake like the big rigs use, it is a exhaust brake. I have one in my 2001 and use it all the time. It basically is a flap that closes off the flow of your exhaust and makes the exhaust flow through a hole about the size of your index finger. All of the exhaust flows throught that hole and it make one neck of a HISS out the tail pipe.
I think it works great. I have pulleed our 5er camper roughly (truck and camper 18K) and another time our gooseneck loaded 19K (truck and trailer with a farm tractor) down the West Va turnpike and I let the exhaust brake do all the work. I did touch my foot on the brake pedal from time to time to let folks know I was slowing down. I had to turn it off to keep from going to slow.

I agree with the above posts if you don't have one you don't know how handy they are. I have one and use it every day loaded or empty and I would never get rid of it.
See Ya
Chris
