Towing Air bags installed

I installed my Firestone Coil Rite kit today. Its freaking cool, i love how it rides and the adjust ability too. I cant wait too hook up to a trailer. Pics are not the best but its getting dark out.

This is the kit i bought here.
http://www.fsip.com/riderite/products/crinfo.shtml

There is another brand called Air Lift but i heard it was much harder to install. This kit took an hour to install and no drilling or coil removal was needed. All i had to do was jack it up to release pressure off the springs, remove the bump stop, deflate the air bag, squeeze it in the coil, hook up hose and top rubber spacer/protector and run the hoses.

I ran both air hoses along the sub frame in the back to the drivers side rear corner. I bought a Tee at a local supply shop and then i ran the single line of hose up behind the tail light. there was a factory hole with some tape on it behind the light so i went through that, drilled a small hole for the hose through the second layer of sheet metal and then mounted the valve next to the cargo tie down and aux power port.

One thing i did notice is that the instructions say 5 to 35 lbs in the air bags but their setup/instructions run to individual air lines per bag and valves. So when i air them up i will need to double the pressure wont it? If my pressure gauge says 10lbs that means that there is 10 lbs in the system so its most likely only 5lbs per bag.

This should really make a huge difference when towing. If i max out the air bags i can get about 4" of lift in the rear end.

Ya gotta love what New England Winters will do to a 2005 WK.

Re: Towing Air bags installed

Niiiiccceeee!


On another note, you need a wire brush and some rustoleum badly. Damn Northeast winters.

Re: Towing Air bags installed

as far as 10 pounds in the system really meaning only 5 or whatever you were saying, if the valve is connected after a y then the valve should read what the pressure is for the system total ( both bags combined)

so:
bag-----airline------
.............................>--- guage.... Then it should read the correct pressure..
bag-----airline------

Yes, the valve is after the Y so it is reading the whole system so to get the proper pressure per bag for each function i need to double the reading the the air pressure gauge.

As far as the rust goes, i am too damn lazy to start wire wheeling and brushing and painting. It will only look good for a little while before it comes back. Id rather just buy a whole new rear sub frame paint it and bolt it in. The rest of the under side of the jeep is pretty clean compared to the sub frame.

Re: Towing Air bags installed

Bought them locally for $90 even but they are about $75 online plus shipping depending on where you find them.

I guess the air lift kit requires you to remove the coil and drill a 3/4 in hole in the spring bucket(mount) and there is not enough room to get a drill in there. These came recommended for do it your selfers over the Air Lift brand.

I dont think so, what you see is what you get...

Combined, it will read the total amount of pressure in those lines...

I have a 2 tank air compressor... and it has 3 gauges... 1 after they combine, and one for each tank before they combine.. they all read the same unless i shut off one tank.. They will equal out as long as the valves come together and the reading is at the end of the 2 into 1

Here is the next best idea i can try to explain.. I have this cool little air hose that i put in my bag for when i get a flat tire riding my bike... I can hook it up to a car tire to inflate my tire... Now even though a car tire has WAAYYYY more air in it than a bike tire, it doesnt inflate the bike tire to 80+ PSI, it only inflates it to the equal pressure the tire has, so like 35 psi.

Re: Towing Air bags installed

Ok, i think i get it now.

Just and FYI, in these pics there is only 10 psi in the air bags.

Re: Towing Air bags installed

10psi = 10psi. It doesn't split just because there is a Y fitting to connect both bags to one fill. Pressure is constant throughout a connected system so you can drop it to the minimum 5psi at the fill fitting and it will be 5psi at each bag.

Install looks good though, definitely like seeing the fill port located inside.

Re: Towing Air bags installed

Yea, i got it now. i was thinking Volume and not pressure.

I have seen so many people put the air valve out side or on the frame or any place it gets dirty and corroded and then it needs to be replaced. If its done right the first time it will last longer is how i look at it. It only took a little be of extra time to get it inside vs under the jeep or in a inconvenient place.

Re: Towing Air bags installed

sweet set-up Kyle...if you get time post up a before and after you level it off with something on the tow-hitch!

so if you wire brush and do a couple coast of Rustoleum underbody spray the rust will just come back???
