Airlift 1000 finally installed! First impressions...

Mcfarmall, I installed Firestone RideRites in my F150 as well last year. It does make a significant difference when handling a large tongue load (900-1000lbs). With 50-75lbs of air you can almost eliminate porpoising. One thing that surprised me was the classic 1/2 ton driveline 'shudder' you get when taking off from a stop with a heavy trailer was completely eliminated as well. The airbag brackets stiffen up the leaf spring to axle connection and reduce twist. That alone made it worth the price of admission!

Raguustin,

Here is probably the suggested process:

Install Air Springs keeping each side independent, do not "T" the fill lines to a single fill nozzle. Air Lift told me that this will provide for better roll control since the air will not go between right<->left bags.

1) Fill bag to min PSI (5lbs).
2) Hitch up TT to TV with WDH and adjust to get best level.
3) Unhitch TT from TV.
4) Fill bags to MAX PSI (35lbs).
5) Hitch up TT to TV with WDH to same adjustment as in #2
6) Remove air from Air Lift for fine adjustment and note PSI when complete.

You only have to do this once. The next time you hook up the TT to TV, you can skip steps 1-3.

My conversation from Air Lift was to always fill the bag to MAX PSI, apply load, then lower PSI until level.

Hope this helps.

James

Excellent explanation James!! That is just how they explained it to me too.

Thanks for all the advice! I have mine installed and have towed for a short haul at max PSI. It was a little bit bouncy, so now it is time to start taking air out until I am both level AND happy with the ride. Reading the instructions certainly helps, LOL.

There is also a "rule of thumb" that you shoul expect to add about 2 psi above min fill (5 psi) for each 100 pounds of added weight. So if my toungue weight was expected to be about 800 lbs, I would be at 21 psi on each side {5 + (8*2)= 21}. I'll try that and then add back in if necessary.

We just bought a new 12 Laramie Crew & put the bags in the coils, it really holds our 308FBS up nice. Remember to check the air pressure often because you will ruin them if run flat & Airlift will not warranty them if over or under inflated.

Well, I've run into a really odd problem with the air bag ont he right (passenger) side. After last weekend, I went to release all but 5psi of the air from the bags and the right side was completely empty (not reading on the tire pressure gauge). So I put 20 psi in it and left it over night. The next day, same thing. No pressure on the right side. I took it to a service centre because I'm going out again this weekend and won't have the time to check this myself. They soaked all that lines, connections and bags with soap and water and tell me they didn't see any bubbles. Then they put 20 psi in it yesterday and it has held (up until this morning anyway).

Does anyone have an idea as to how you can have a phantom air pressure problem? This makes no sense to me.

After you set the pressure where you want it, you'll need to go back and readjust the WD. When you change the rear height of the truck, you are changing the tilt angle on the ball, the tension on the bars, and thus the amount of weight transfer. Once that is readjusted, you need to tow with the same amount of air in the bags every time or the WD is going to be different. For some reason people seem to be more concerned with how level the truck sits rather than if the right amount of weight is being transferred back to the front axle.

The right side bag is now holding air. The only difference is that I didn't put the cap back on. Maybe that was the culprit?

I'll get to find out this weekend when we're on the road again.
