Your Overlander NEEDS Air Bags! Fast DIY Onboard Air Episode 3.
today on dirt lifestyle we're going to try to finish up a truly one-of-a-kind

onboard

air system in the last

episode

we finished assembling our primary manifold and got it mounted on the chassis we then fabricated a secondary manifold using a drill press and some taps and used that as a way to distribute air to our front and rear air locker and air truck that we have mounted in the rear of the vehicle so we always have access to our

onboard

air anytime we're on the trail i have such a hard time finding exactly what i need to manifest these ideas i know a lot of you guys know this is like our one number one problem if you're a creative person you're trying to build one-of-a-kind four by fours is you'll come up with a cool idea but it's so hard to find the parts you need in order to make that idea a reality so i have been looking forever for an air actuator that can be controlled in the cab that will allow me to fill and empty air

bags

at will and there's a few different companies probably that make stuff that are similar to what i want but not exactly what i want and summit racing happened to have exactly what i needed for this build so i reached out to them i said hey do you guys work with smaller youtube channels and you know just check out my channel if you like it i would love to work with you so sure enough they like the videos they sent out the stuff that we need in order to make this video happen and uh i'm super happy so everything you...

see on this table every fitting every piece of airline the controller all this stuff can be found at summit racing and if you go to the description this video because you want to find this specialized air actuator you can click on the link it will take you some racing and you can find it you don't have to do what i did and just like continuously feed weird search terms through google you can just click on the link in the description it'll take you to summit and you can get this stuff so the way this system works is that we have a controller this is from a company called ridetech this controller communicates to an air actuator that we're going to remote mount through a harness that ridetech also makes so this is going to make it to where i can inflate and deflate

bags

at will as we're going down the trail and some of you watching might think why would you ever need that let me tell you why if we have these you've got two air

bags

each one's going to go inside one of the rear coils if we are out of level because this is a really tall discovery with a heavy rooftop tent all this stuff on top and we're getting really leaning around that obstacle we can inflate this bag we can deflate this bag and make it where we can level the chassis out a little bit we can give it a little encouragement but also just as simple as sometimes i'm gonna be camping by myself and i'll need a certain amount of gear for that other times i'm gonna have my wife and...

my two kids and all of our water and food and all that stuff that's gonna be completely different weight on the vehicle and you can't get a spring rate that can handle both of those demands so these air

bags

are gonna make it to where we can because if we need a little bit of a boost in the back because it's starting to sag from all of our gear or we have a trailer hooked up or whatever the situation may be we can give it a little boost with these air

bags

level everything out and we can even go as far as stiffening the ride for better handling on the highway or softening the ride for better better handling in big potholes so anyway this communicates with this through a wire harness we are going to have these

bags

uh connected to our actuator with some quarter inch line we have eighth inch line that is going to go from the actuator to the gauges this is a dual gauge setup so we're going to have i think i'm going to do the red gauge will be the passenger side the white gauge will be the driver's side and i also lucked out in another way and that is the fact that these air

bags

from firestone and this actuator from ridetech both are quarter inch meaning that the line that was sent for both kits is the same size and i love that it's different colors because i can make the passenger side blue i can make the driver's side black and i think a good place to start is mounting our controller in the cab and then we'll just work our way out from there ...

when prepping everything for install i removed the switches out of this control panel to make it a little bit easier to screw it into the piece of plastic that i think i'm going gonna mount it to i then apply double stick tape to the back side of this actuator intending on using double stick tape in conjunction with screws to make sure that this won't fall out of there on a hot day or rattle around if these screws back out a little bit i then applied a little bit of construction adhesive on the threads of these screws to give these holes in the firewall a little bit of weather resistance after getting the actuator secured it was time to run some air lines through the firewall and there just so happened to be a blank grommet in the perfect location to feed these air lines now we can move on to the switch panel and one thing that i've learned with projects like this is it's nice to prepare as much stuff on the bench as you can before you get into the vehicle so after mounting our two air lines to the back of the gauge we can move forward and figure out a way to secure this in a location that makes sense we're finally to a point where we can do our first series of tests and the reason that i want to test some right now before this system is done being installed is i've got a whole bunch of loose line everywhere that i want to secure and zip tie and i want to make sure that all the push to connect fittings are tight before i like anchor it in...
really tight and then later on if i find a leak i'd have to snip all those zip ties out of the way so what what the plan is is i'm going to fire up one of these compressors i've got this little temporary gauge that i made up so we can monitor the pressure i want to get it up to around 50 psi because around 50 psi you can really start to hear a leaky fitting whaling and then we're gonna kill the compressor i'm gonna walk around and i'm just gonna listen for leaks i was very apprehensive about using plastic fittings in this system specifically for reliability but i've had this dryer sitting in my toolbox for 10 years or more and this felt like the perfect time to get rid of it unfortunately the bottom part of the dryer was cracked rendering it useless with an easy out i was able to get the remains out of the threads and bypass it all together according to the gauge the system is holding air just fine but i want to go around and listen for leaks myself after confirming there's no leaks anywhere at least not any massive ones i aired the system back down and it was time to install the rear air

bags

in most applications these rear air

bags

can be folded up and fit in between the wrappings of the coils but with these springs in particular i think that it's a little bit too tight so i decided to just drop the rear axle pull the coils out and fit them in that way this air system is ready to rock and roll um except for one big snafu but we can still...
test it so the snafu is we have an aftermarket lower coil spring seat that is uh for the land rover discovery and the way this is shaped is it's shaped kind of like in a pyramid to make it to where whenever you have one wheel flex all the way out it's uh this coil can loosen up and it can come out and that's not a problem we're gonna have because we have limit straps on here so we're just gonna make the limit straps long enough to where uh this coil can't get loose on us but i wasn't sure how this relationship was gonna end up between this coil spring seat and this airbag and as you can see it's bunching up that airbag and it's something that might work but either way i'm going to order the oem coil spring seats for this because it's ten dollars aside it's an easy install i mean i can have these coils out in less than five minutes because there's so few things i need to take apart in order to access them so in the future that is what we're gonna do but for right now i'm gonna bolt the the wheels back on this and we can fire up this air system and see how they work this air system is clearly a work in progress we now just have like the skeletal system of this built but i still consider today a huge win we have a system that is holding air we are at just under 40 psi right now and it's been holding there for an hour so we're holding air the rear air

bags

are working that ride tech gauge setup is super sweet i...
think i like that it's really low profile very practical and i think that it looks good in there so all those systems are working great the air the air pump itself the air compressor is filling super

fast

and this isn't a very big system but it's nice to watch the needle just go up like that that's only on one compressor once we fire up the other compressor it's gonna be twice as

fast

so i'm very much excited about this system i think that we're going in a good direction we right now we probably have like an inch and a half ish of movement in the rear with those air

bags

so not a ton of flex but these aren't made for that however in the future if i do decide that i want to have like you know five six inches of travel i can replace the rear springs altogether and i can just put a big massive air strut back there and we can get a ton of wheel travel out of it so we'll see this is version 1.0 i think this is going to work for our

needs

perfect because if you're parking somewhere and you want to level out

your

rooftop tent an inch and a half bump on one side is giant usually you're trying to find a place that's pretty flat anyways so i think that this is going to work really well for those types of situations i'm not going to do the electrical system portion of this air system just yet i'm going to do that when i do the entire aftermarket electrical video for this discovery there's a ton of lighting that we're gonna...
add there's a whole bunch of switches there's there's so much work on the electrical side of this that i figured i would just incorporate this portion into that video then at the end of that one i'll probably play with the air system a little bit more but for now the air system build on this discovery is done let's run through a couple comments from the last video which was

episode

2 homemade manifold with basic hand tools that is that's a mouthful but i gotta get all the search terms in there first question is from 60 foe would you need to step down the air pressure for the lockers pretty sure they don't run at 120 psi so i looked at the manufacturer's recommendations and i think the minimum was 85 and the maximum was 110 so 120 is definitely over that and i originally had a prv in line that was 100 psi but it turns out i couldn't make it work so i'm going to revisit this right now the maximum pressure of this system is 120 i don't think in my experience that would damage these lockers but i would like to get it down to like 100 just to be safe so that's something i'll address in the future next question is from it medic three where did you get the air chuck that is mounted inside the goal wing i need a new set for my garage i'm tired of the harbor freight ones leaking these are from uh these are from home depot they're just husky brand i've had really good luck with these i had the same...
experience as you if you just get the off-the-shelf um just brass like cheapest cheapest air trucks you can get they always have leaked for me but these ones from husky seem to be working a lot better so that's why i decided to buy those for my discovery as well because i'm having good luck with them in the shop charlie toner says check out speedflat for air up downs ps not sponsored i use their system and it was built better and less expensive than i could do in my shop so there's a bunch of companies that make these speedflat style uh inflation and deflation systems and basically it's just like one port you uncoil a couple well a few hoses you un coil four hoses one to each tire and then you can deflate everything at once or inflate everything once and i think they're pretty slick but it's just not for me i full disclosure as youtubers we get so much stuff that is like people emailing us that they want to send us stuff like that i've had so many companies that make that exact product that have said hey i want to send it to you for free it's just not my style it's just that simple so maybe one day i'll change my mind but right now i don't like the idea of having to uncoil all these hoses and whatnot rather just have one hose one filler upper just go around and fill each tire one one at a time next comment is from abp sd73 should have a pop-off relief in case the pressure switch fails and the compressors keep running yes that is...
definitely part of the plan i i need to stress this i used to act seriously i used to build these systems commercially for a living i uh i know of all the things that it takes to make a system like this fully functional and safe and all other stuff but it is way easier for me to find the industrial stuff that i would use like i did the bass pro shops in tacoma and we have air system in there and it was easy to find all the stuff for that air system because it's all it's all commercial grade big stuff it's harder to find it for the automotive space so these are things you're going to see me add in the future right now are just getting like the bare bones of this system built and in the future i'm going to start adding some little things here and there and i've got a whole bunch of ideas for this
