US Gear D-celerator exhaust brake

[TFlewitt]

I think I want to install a 4" exhaust brake under the truck so I can take it with me to the new truck in a year or so. Anyone else make one besides US Gear? Talked to them and they said if shaft is lubed once a year, should have no problems with sticking. Any thoughts? Where for best price? Thanks!

I have been looking into the D-celerator brake also. Anyone have additional info?

I've sold several exhaust brakes for in line installation for those guys who have upgraded their turbos and the direct mount won't fit...



The problem with an inline brake is the requirement for welded connections to prevent leaks... and the time delay for all that pipe to build back pressure... . If you have no intention in changing your turbo. . I suggest you mount a direct mount exhaust brake like the pacbrake C44045 with the PXRB technology for greater back pressure...



When you go to move on... you pull the exhaust brake and reinstall the elbow that you took off... . this is the best of both worlds. .



The pacbrake elbow is larger than the stock elbow. . and is designed to flow more air allowing you to upgrade the HP and increase air flow without a problem... .



Hope this helps... . BTW if you have an automatic in some cases you'll need a kit to lock up the torque converter...

I had a 4" brake on my 94 for about a year, then changed to a 3". The problem I had with the 4" was that the back pressure never got above 40psi (2500 rpm). With the 3" it jumps up to 55-57# at 2000 rpm. I think that there is to much flow/leakage around the circumference of the larger 4" butterfly for the 5. 9L engine to develop maximum back pressure. The 3" valve has 75% of the sealing area that a 4" valve has. If you want a 4" inline kit I have one in the classified's.

The pacbrake requires an air compressor, correct? Does the inline us gear inline require an air compressor? I would like to have an electric one and it was my understanding that the usgear was electric?

The US-Gear ones that I have had were electric solenoid operated.

Here is their application web site.

Ian... .



The pacbrake in line brakes can be adjusted for back pressure as it can be used on several different trucks with different exhaust valve springs... I can only assume that all in line brakes are the same... when we install an inline brake on a Cummins we set it for 60 psi... . some other trucks because we can't get HD exhaust valve springs we have to set down to 40 psi... .



We just did 2 Fords, (Brazilian) with Cummins engines... we had to change the exhaust valve springs to HD springs and set the brakes to 60psi of back pressure... . customer was very happy... he sprays the side of the highway for the state and used to wear out the brakes going down hill... .

I did the same as Jim with the Pac-Brake. It is electric over vac and works very well. It does not have to be lubed either.

What do you means, electric over vac? Trying to gather as much info as possible. First time buying an exhaust brake, just want to get it right.

Being that you are already a BD customer, May I suggest a BD inline 4" brake it can be adapted to any vehicle, requires no maintenance other than checking back pressure once a year, No disassembly and we stock them.
