Easy to install suspension dump setup on your Cascadia 2009 to 2017, DIY

[@kmg501]

I don't recall ever seeing a tractor without a suspension dump valve in the thirty five years I've been driving, I'm surprised that it was factory omitted. What I really want is a override valve or control in the cab to over inflate the bags temporarily. Yeah I know that could be a disaster in the hands of a dummy. I'd even take a override control on the frame behind the cab. On another note what I am seeing a lot of these days is no trolley control lever which pisses me off to no end and would be completely unacceptable on any tractor I owned. Nice job you did there, pretty simple to other than having to make the cut in the panel but you did a good job of measuring and laying down the cut lines.

I enjoyed video. I'm replacing some old school switch mess with factory style. This video helped alot. Thanks

[@Little.stJames192]

I have a 98 fld120 and this exactly what I need to do. The only switch I have is the axel lock.

[@CarlosDieselElectric]

@@Little.stJames192 pretty easy setup. It should be similar on most Freightliners. Open up the dash and look at the other switch. Should be air activated. Just follow the video and you should be good to go.

Great job! Thanks a lot!

Nice one sir happy new year

I may go this route , I got that extra expensive suspension adjustment with a dummy axle. One of the modules are leaking air . I can’t find a rebuild kit here in the USA. Only rebuild kits are in the Europe market. Replacement of each control module per axle is 500+.

[@jarvis4712]

I have that identical axel. The airbag sensor for the Ecas is a pain always leaking air. I'm ready to convert into a 6by4

Thank you man

[@GabrielAlvarez-lf2lt]

Nice video I just bought a 2019 International LT it doesn’t have a dump switch can this be done the same way thanks

[@CarlosDieselElectric]

That I am not sure of, I believe you can but may require some programming on the cab side especially if it is electric. However, if you wanted to go with a setup like the Freightliner, you should be able to but it may require more research on the height valve.

Carlos buenos días yo compre las partes pero ellos me dieron un cable electrónico que va ay en el aparato tú no lo ocupas poner? Yo creo que es la alarma

[@CarlosDieselElectric]

@@jesusnunez3583 puede ser para alumbrar. Aveces se necesita pero trabajo sin el

Great video I did exactly same thing to my 2017 and I was done in two hours and everything work flawlessly I would appreciate it more if you give more information about the electrical connection I don’t know if the harness or plug is there or I don’t know what kind of connection we have to do so if you have that informationI would appreciate if you can share

[@CarlosDieselElectric]

Freightliner does sell a jumper harness, it should be a plug and play. Let me see if I can find a part number.

[@JoseMartinez-jl1mk]

I think the harness just for red indicator light only.

[@JoseMartinez-jl1mk]

If you disconnect the plug, the air dump function still good. Just red light remind you the switch is on.

[@vybz876]

Notice you have the 1/4 inch black line from the valve to the switch, and the white jumper to the 5th wheel. Where did that yellow line to the switch came from?

[@CarlosDieselElectric]

If I remember correctly, yellow comes from the cab air supply side on the Freightliner side. Let me double check

[@JoseMartinez-jl1mk]

👍🏿👍🏿

How about for a 2021 cascadia ? I want to install a dump valve in to mines … my cascadia only has the air slide lock . I want to also install a sliding 5th on mines , but would like to get the dump first

[@CarlosDieselElectric]

Since you are just using air, you should still be able to do something like this video. Just need to find an air supply (source) and then everything else should be the same. The newer Cascadia use an electronic switch and I’m guessing a solenoid to activate the air. Kind of like Peterbilt and Kenworth trucks. But Freightliner may require some computer work on the chassis side for the signal.

[@dynamiqforce]

Can you install on a 2019 international LT625

[@CarlosDieselElectric]

@@dynamiqforce I imagine can, the only issue may encounter is the leveling valve. I would recommend you look at another truck that has the feature and go from there. You can always install a manual switch and height leveling valve. Just needs air to make things easier

[@dynamiqforce]

Thank you that’s what I’m currently doing now because the dealership told me about reprogramming

[@CarlosDieselElectric]

@@dynamiqforce Newer trucks are controlled electronically with solenoid.
