Has anybody used a d-celerator from US Gear
Are thay any good with the 47re or stick to pac brake.

Thanks,
John

 

I'm also looking at in-lines and they are on my list. Pacbrake, BD and US gear have in-lines. Craig

 

I have the US Gear D-Celeratoron my truck. I Fulltime RV towing a 14,000# 5th wheel and on a 6% grade it will hold ~42mph in 3rd gear. It uses an automobile type solenoid and is activated by a small on/off pushbutton switch that can be mounted (via sticky-back tape) just about anywhere. It comes on instantly and produces ~59# of back-pressure which is controlled via a small by-pass butterfly valve. Also very quiet in operation but does produce a loud 'clonk' when activated. It does work....well enough that my GF no longer grips the 'chicken' bar, stomps the floor board and screams "We're all gonna DIE" when we are cruising thru the mtns!!

 

I have had it on my truck for 3 years now and it works great.I've had no problems at all.

 

Is this the standard or the Super Duty D-Celerator?

So what is the difference between the 60# and the 35#? They are both the same price through RVExit. I guess what I'm really asking is, why would you go with the 35# when you can have the 60#?

 

From what I've read ~60lb are the good ones and the low psi ones are only good for light loads. Some only have a hole in the butterfly (typical of the low psi brakes) and only produce 20 psi - what a waste! The good ones use a wastegate or some kind of regulated (I think by a spring) means to keep the pressure up to the max. None that I've found are variable - full psi is what they always do. US Gear is $1295, (electric or air) but none of the air stuff comes with the air operated brake cuz they usually sell them for bigger RV/TVs that have airbrakes or other air accesaries already. BD and Pac include all the air stuff in their air operated brake kits. Both have air kits w/tank, hose and accesaries for airing tires, blowgun etc. If you don't need or want onboard air the US Gear D Celerator would keep things very simple. Craig

 

MikeyB My is the Super-Duty. Has two butterfly valves (one large 4" I think and a small one to regulate backpressure via spring pressure). The large one slams closed when activated and the small one regulates to maintain 60# of backpressure (Mine holds ~59#). Very simple.....no worries about split/cut air lines although an onboard air compressor would be nice (but I have a good one that is very portable and is stowed in my 5'vr.). Hardtack

 

You will not be able to run a 60# version on unmodified 12 v trucks - their exhaust valve springs are not strong enough, hence the need for 35# brakes. With newer trucks, their springs are 60# and the brake can go all the way up to that.
The pressure regulated ones (US Gear SD, BD and PRXB) are different from non-regulated in that they have a proportional device of different designs that allows them to keep max pressure in the manifold at low RPMs. Other brakes will keep only a portion of that pressure since they always bleed some exhaust off through a calibrated orifice. This is why they are most efficient at over 2000 RPM and that is why I did not get one of them - I use it a lot under 2000. My proportional BD works great all the way down to 1200.
Search Performance forums for exhaust brakes and you will see many threads on comparisons of US Gear with other brands.

 

I had one on my 2001 truck for the three years I owned it. Honestly, I didn't like it. Mainly because of the VERY loud CLANK! it made whenever you activated it. Add to that the fact that when you start the truck, it automatically does that twice. If you don't let it, carbon build up will restrict its movement and it won't work. So no matter what, you get to live with the loud clank and the strange looks from people.

Next time I'll get a Pac Brake.

Thanks for the replies. but just how loud is the "clank/clonk" at activation of the unit and does it happen when touching the throttle with out turning it off.

Thanks
john

 

It is LOUD......it happens when it closes. It automatically cycles (close/open/close/open) when you turn the key on and is loud enough that is scares the %$^# out of anyone standing close to the truck and people WILL look at you kinda strange. When driving down the road you will hear it after you take your foot off the throttle......I don't mind the 'clank'......lets me know it's working and I like the strange looks especially from mechanics (simple things in life give me joy)!!

 

I also read somewhere that the solenoid on the US Gear takes about 80 amps to activate, that is some serious draw. If any electrical gets corroded under the truck there, it will not work well with that kind of draw.

 

Thanks for the info on this unit.
Iv got a 05 and the only other brakes I found had to add more electronics to get them to work with the auto.

 

I think any e-brake will require more electronics to work with an auto. You have to tell the auto to lock up in order to use any E-brake.
