Air Lift 1000 Questions

adboyd06 · May 31, 2016

I have decided to purchase the Air Lift 1000 to help with rear sag when hauling and I have three questions:

1. Is it best to run the T air line routing or dual air line routing? Positives and negatives for both?

2. How long does it typically take to deflate both air bags back down to 5 or 10 psi after being fully inflating to 35 psi? Does anyone install a dump valve (or something similar) to deflate faster?

3. Is it necessary to wrap the air lines in anything for added protection, if so, what do you recommend?

Thank you. Truck is leveled with Bilsteins at 2.1. Broke up a 8'x10'x4" concrete slab, took three trips to the local dump. Now for some pictures:

I chose not to run the T on mine because I feel it will do a better job at preventing sway if the load shifts to 1 side on a turn.

It only takes a few seconds to inflate of deflate these because they are so small.

And I did not wrap my lines, but I was also careful as to how I ran them so that they do not rub on any sharp edges.

Exactly what he said ^^.

Depending on how you use your truck/what you need the bags for will determine whether or not you want them T'd together or separate. If you are hauling weight in the box itself a lot then you probably will want to keep them separate in case the load does shift as stated above. However if you're towing more frequently then you aren't as concerned about load shifts, just leveling and the bags could be T'd together with no issues.

I ran them with the "T" and schrader valve right next to the license plate. I mainly tow so a shifting load isn't much of a concern. Was more to get rid of bounce.

I just leave mine at 30 PSI. Rides fine for me.

Sounds good, I appreciate the info. I'm going to go with the dual air line, better to have the option to leveling loads left to right.

Just so you know, these aren't "leveling" bags in the traditional sense where they go between the frame and axle. They are helper bags that are stuffed inside of the rear coil springs. When inflated they press out on the spring increasing the springs resistance to compress. To level with this type of system you'd essentially have to load your load, see which way side it's sagging to, unload your load, add air to the bags and re-load your load hoping you got the right pressures.

I can watch each side of my bed lift/lower as I inflate/deflate the bags...this is while loaded. I dont see any reason to have to remove a load before putting air in the bags.

Don't see how that's possible, unless it's a light load. These bags are designed to inflate horizontally, not vertically. Then again, I've not hauled any significant loads, just trailers with 500-1000# of tongue weight.

Last time I raced, I pulled my regular cab on a heavy car hauler (7800lbs truck and trailer). I inflated the bags after hooking up the trailer, and it lifted the back of the truck just over an inch.

Did the same thing last week when pulling a much lighter 2000lb utility trailer.

The Airlift 1000's will raise the truck vertically a slight amount as that's just how pressure in a bag works. However Riccochet is correct in the operation of the bag; they are meant to inflate horizontally to put pressure on the coil to reduce sagging and therefore are meant to be inflated BEFORE any load is put on the truck. Airlift themselves have made that claim. I forget if I read that on their website, in the instructions, or on another forum as it was a couple years ago.

They'll lift the rear of the truck as you air them up. They basically get in between the coils and force them apart.

Update - I was able to get the bags installed yesterday in about 2.5 hours from start to finish with a little bit of screwing around and some rain. Ended up taking the wheel liners off to get access to the top of the bags. So far very happy with them, no hauling or towing experience yet but just driving around with 33-35psi the ride is barely/slightly stiffer/bouncier over bumps.

Now for the measurements...Before - ground to wheel well measurement was 40" up front and 40" and 40.5" in the rear. After - with bags inflated to 33psi ground to wheel well is 40" up front and 42" and 42.5" in the rear.

Did you use the 'T', or run separate lines?
I used the T when I originally installed mine, but removing it and running separate lines helped me rid my towing setup (32' bumper pull travel trailer) of sway by not allowing the air to shift between bags. If you only haul heavy stuff in the bed it would probably not affect it as much.

I ran separate lines to my bags, had the valves run out thru the top holes in my liscesne plate, most don't even notice they are there!

I ran the T...I air up before I put any load on it raises an inch in the rear over stock

Installed two separate air lines, literally takes 20 seconds to air them both up with a compressor and about 5 seconds to deflate. Put the valves in the two holes near the hitch, perfect spot.

I bought mine from AutoAnything, with free next day shipping total was $87.42.

That's exactly where I put the valve on my truck.

I use a high volume bike tire pump. Can go from 5 to 30 PSI in like 4-5 pumps.

I ran a T on mine. I tow 6-7k# everyday. I ran my valve inside my gas fill area
