I am a new Sierra owner and am now looking to do some personalization to make it officially mine. One of the items that I am wanting to do is installing an onboard air compressor and tank. I want to have the ability to air up tires if needed for the dreaded roadside visit.

I have a tank that I will be fitting up under body, but what I would like to know is if others have installed one of these units, where the air compressor was mounted, switch location and any tips or tricks that they may have done to make the install clean and hidden.

 

Thanks in advance for any and all responses.

I seen some guys, mostly Jeep guys use these. http://store.arbusa.com/ARB-On-Board-High-Performance-12-Volt-Twin-Air-Compressor-CKMTA12-P21341.aspx

 

I thought about adding one as well, back in my younger days I was roadside tech during my first year as a MB tech, they made us do it to get experience. I always need air, so many folks never check their tire pressure until its too late, esp.. the spare tire.

 

At home I have a 80 gallon quicy air compressor, on the road I have a tiny compact 12volt tankless air pump, takes a bit long but works.

 

It would be nice to see someone make use of all that open space between the outer & inner bed after the rear fenders, if you have rear fender wheel well guards its fairly clean in there.

Thanks camcamaro,

 

I had a Jeep that I was planning on putting this tank and air compressor on, but my wheelin buddy passed away and I lost all interest in the Jeep. I am looking forward to installing them on my Sierra though. I am planning on the tank up under the bed, but not so sure about the compressor install location yet. The spare battery tray would be great, but I'm thinking of adding the second battery.

Another question is, where in the world do I mount the switch???? All that leather trimmed panel sure makes me leary of drilling anywhere to install a switch!

 

I will keep you posted on what my decisions are and I will try to post a few pics as I get into the install.

 

Thanks again,

Scott

Sorry about your friend.

 

I have a console in my truck, for the switch I would guess the lower rear map holder areas towards the rear inside pocket, or bottom/lower side of the "inside" of the center console.

 

from Jeep forums the ARB compressor is compact enough to be mounted in the engine bay area, or maybe the inside of the frame.

 

I am a fan of this, as I would rather just carry it with me when I need it vs mounting it and running the wiring = https://www.amazon.com/ARB-CKMTP12-Performance-Portable-Compressor/dp/B007KEVN00/ref=pd_sbs_263_5?_encoding=UTF8&pd_rd_i=B007KEVN00&pd_rd_r=X4113WHCX4Z7MGBB096B&pd_rd_w=q60lT&pd_rd_wg=Ipoix&psc=1&refRID=X4113WHCX4Z7MGBB096B

I bought the AirLift Quickshot air supply kit. 2 gallon tank and compressor. Only place I could find to mount was passenger side between frame and steps. I bought Firestone's mounting brackets which matched up fairly well but they protrude farther than I'd like. Thinking I may have some custom brackets made for a cleaner look. I have a second battery so engine compartment was out of the question but you're not supposed to do that anyway due to heat.

I haven't installed yet but I am in the process of getting organized to install an Airlift 7200 wireless system to control the airbags on my truck. One of the things I came across while searching for install ideas is that a lot of sellers do not recommend putting the compressor in the engine bay. Apparently over time the heat may have adverse effects on the compressor functionality. That being said I have also read where a lot of people have put them in the engine bay and stated that they have not had any issues. YMMV.

 

One thing I did see online that I liked and am copying is where a guy took an ammo can and mounted his compressor on the inside of the lid, cut breather holes in the floor (now ceiling) of the can and then mounted the whole thing upside down to the frame rails of his truck. The idea being that the ammo can provides protection against debris, salt and water. His thought was that if he ever needed to access the compressor he could open the lid and the compressor would swing down from the underside.

 

In any case that's where I am at the moment, trying to shoe horn things into a 50 cal. ammo can. Whenever it stops raining I'll climb up under the truck and figure out a decent spot to mount the thing. One idea I had was to purchase a waterproof computer fan, mount it over the ventilation hole and wire it up so that it comes on when the compressor comes on. (Probably way over kill, and I likely won't do it.....but it seemed like a need thought at the time)

Another option that's always been interesting to me the Power Tank setups. Yes there are long term costs/fillups but I'd much rather put it in the truck when I need it, or mount it to the bed, can think of all sorts of uses. From what I've read the average 10lb tank is good for about 4 x 4 tire fill-ups from offroad pressure (16-20?) to road ready (36+).

What would the long term costs be? Can't these be filled with a home compressor or do they require specialized equipment? I guess I need to do my homework!!

The tanks are compressed a lot higher than the typical DIY air compressor is capable, that's how they have enough volume to fill multiple sets of tires. Someone might know better, but those might be compressed far enough that the gas becomes a liquid (think propane).

 

I own a Puma 12V air compressor, basically a 12VDC version of a portable 120VAC air nailer compressor...has a small tank and decent compressor.

I have a viair 450c with 2 2.5 viar tanks on a 110 on 14( off pressure switch. I wired a Bosch relay into the gm stock upfitter harness and later added in wiring it to the inadvertent power controlled by the bcm. I run train horns and a full filter water separator that's mounted on my tool box. I run 1/2 ID brake grade line and push in DOT connectors. It's the easiest, most durable and leak resistant setup I could find. The compressor is 100% duty cycle and this is the 3rd truck I've ran it on. I don't beat it up too bad except a blue nozzle to clean truck, occasional impact gun and train horns like it's my job.

 

I made a harness to tap into the upfitter port by the pedals that's oem parts. I'm selling them since I had to purchase a large quantity of parts to get them cheap. GM sells the un pinned parts for $68

 

I'll build, pin and ship ready to wire for $45 plus $6.80 shipping

Daniel,

 

It is obvious that you are much better versed at electrical work than I am. I do like how you have these set up for a clean finished install. Nice and neat makes it easy to trouble shoot if needed.

 

Thanks for the info and if I decide how I am going to do my install, maybe I will order one of these to tie it in.

Thank you sir!

 

I learned some lessons about inadequate wiring the hard way when I was young. I'm happy to help out any way I can.

 

There are plenty of resources for wiring in these trucks available if you have any questions. Tons of people on here can help too. Best of luck!

This harness will provide two battery power sources, 1 Rap accessory, 1 crank accessory and a ground. It is very useful in adding any mod. I just wanted to clarify due to some inquiries. My harnesses are soldered at every joint and will handle far greater current than factory equipment. I will offer wiring support for anyone that buys one and stand behind my product as long as I'm alive and able. They come with braided friction shielding and I can custom build and write up plans for just about anything you want to install. This is just something I do to make things easier and since this is my hobby. Any questions, please feel free to openly post or pm.

 

If you know you are going to order please include name, shipping address, email address truck info to include trim level as well. Thanks for your time. I currently have a couple left pre built but they are going faster than anticipated. I've place an order to replenish supplies so I should be able to maintain same day shipping.

      Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.

      Towing In Loose Gravel

      By Another JR · Posted

      The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts.

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.

      Multigate electrical problem

      By Another JR · Posted

      The recall is for exactly this issue - those drain holes combined with the limited environmental capability of the tailgate electronics card inside the tailgate were a problem. The “safety issue” was the potential for the tailgate to spontaneously open, but all kinds of tailgate misbehavior can occur from water contamination of that control card.    There is no real fix yet. The initial recall just disabled the tailgate. Later, when parts became available, they would replace bad parts with new parts of the same bad design. My dealer is going nuts because the few times I let them get their hands on my truck, my tailgate is off due to a slide-in camper installation. They really want to cut my tailgate wires, but I won’t give them the chance. I will let them get their dirty hands on it when a real fix (redesign) is available.  My tailgate, which works just fine with sealant plugging the drain holes, will remain safe in a dry storage crate until then.
