I just got a set of King air shocks and they didnt come with any instuctions on how to fill them or with what. Do they fill with nitrogen like the Fox Or with regular compressed air? I figured if you spend that much on a pair of shocks they would at least give you some info on how to set them up. Has anyone had a set before and can give me some info?
 
The fill with Nitrogen. Do not use shop air.......

You can probably get some info off their website. Depending on what type of vehicle you have, you probably can start around 250 on the pressure and go from there.

If you need any assistance let me know

All "air" shocks regardless of make get filled with Nitrogen.

King can probably tell you max oil volume, pressure, etc., just don't expect them to tell you what volume & pressure you need for a Jeep. ;)
 
I have looked on their web site and all there is is information describing the shocks no information on the use or set up of the shocks.

Call them. They've got a good tech support dept, I've spoken at length with one of 'em.
 
If you dont know how to setup air shocks, you probably shouldnt. They are not supplied with instructions b/c there is nothing for basis. Each application, ie: travel, weight, rebound, dampen, is different for each and every vehicle they are mounted on and individuals ride likings. A quick rundown: Most air shocks are shipped with a 60/40 dampen/rebound. The compressed nitrogen will only net you ride height, not ride quality. You can add oil through the shrader valve to adjust compression, ie: soft/hard ride. To adjust the rebound, the shock needs taken apart and the washers swapped. But, a little trick of the trade is different weight shock oil with give different rebound results, ie: a 20w shock oil has a slower rebound as where a 5w oil will rebound quickly.

Most DIY apps are ready out of the box, just add nitrogen and go. If you want a stiffer ride, deflate and add a few cc's of oil.
 
I hade them set up when I had them built from the company I just needed to know what to fill them with and how.

You adjust the spring rate and curve by how much n2 and oil you add. I'd bet $5 they put the same amount of oil in yours they do with every air shock... they MAY have set up the valving a little different, but that's it.

It's still up to you to set them up.
 
You fill them with nitrogen using a nitrogen fill kit. You can buy one for a couple hundred bucks or you can ask around on here like I did and find someone who has already bought the fill kit if you can borrow it. It takes all of 5 minutes to fill them up and then a while to tune them in. If you are setting up on all 4 corners I would suggest buying your own fill kit so you don't have to keep asking someone for help when you dial them in.
 
First, you need one of these, or you can make you own setup.

If you have a N tank and regulator you need this.

Then you need to mount the shocks, and let your suspension droop to where the shock is extended ALL the way. Put in about 180 psi is all the shocks, and see what that gets you as far as ride height. If it's not enough, add some more. You will have to do this several times. The first few times you drive it, they will settle, and you will have to add N a few times to get it right.
