Easy airing up/down

[djkaosone]

Not sure about you guys, but airing up and down takes forever and bending over to do it isn't fun anymore.

I decided to put (5) schrader valves (1 at each corner and a single schrader valve up front), dot rated 1/4 od tubing, and (3) 1/4 tee push fit connectors. I also made (4) 24" air line with air chucks at each end to connect each tire to each valve stem.

RH side view of both Front and Rear:


RH front:


RH Rear:


Centralized air inflator/deflator:


Tested to hold air with all 4 tires equalized pressure:


To deflate, I simply attach all 4 blue air line extensions to the tires and deflate all to 30 psi. Detach rear blue airline extensions, deflate the fronts to 25 psi. Done. Now I'm 100% sure the front has equal pressure at 25 psi on both L and R sides. And the rear is the same equal pressure at 30 psi.

To inflate, attach all 4 blue air line extensions and inflate all to 40 psi. Detach the fronts and inflate the rears to 45 psi. Done.

I'm using a Viair 400p and airing up is a breeze.

Great innovation! How are you storing the air lines when not in use? Given your awesome fabricating skills, I'm guessing some form of bracket in the wheel wells?

I'm storing them in the same bag as the Viair 400p.

This is my phase 1, getting the air lines in and working.

Phase 2 is getting an air gauge on the line for quick readings.

Phase 3 would be full on-board air with air tank independent of the suspension and auto shutoff. 120 psi auto shutoff at holding tank, well below the rated max pressure of 250 psi. Working pressure will be 90 psi. Tires will be well under 60 psi, more like 40 psi up front and 45 psi in the rear for daily driving. A lot less for off roading.

Given your awesome fabricating skills, I'm guessing some form of bracket in the wheel wells?

Not this time. I simply drilled a hole into the plastic wheel well that wouldn't get in the way.

You're still taking the compressor out of the bag and alligator clip-ing it to the battery at this stage? I'm planning on putting a viair 300 where next to the brake booster like I saw either here or on another forum. No need for a tank to just air up tires.

For now, yes. I have a secondary battery next to the brake booster. I'm still in the testing phase and will head out momentarily to test it out in the field.

Phase 3, will be modifying and installing a secondary oem air tank on the opposite side, hard mounting my Viair 400p, adding an automatic pressure valve with cutoff switch (at 120 psi) to the 400p, and plumbing an actuator between the tank and the current system. This will allow me to turn ON the compressor at any time, then flip a switch to for the actuator to release air into the system to fine tune pump air into the tires.
