Air coilover? (running coil springs with an air shock)

I haven't seen this talked about but I am sure it has, my seach brought up a whole lot of nothing.

I have been looking for a versital set of shocks to run on a truck that will be used for R&D of my "Mid Arm" suspension system. I have been looking for a rebuildable emulsion 2.0 around 10" travel. But while searching I came across Radflo's Air Coilovers... And this got me thinking...

If I am running a spicific coil... say 150lb rate for crawling and I wanted to bump up the spring rate and ride hight for some go fast. I could use the air shock to do this and still tune rebound and compression too. Not running for hours in the desert. While it is 1:00am and my thinking may be wrong, this seems like a pretty cool/good set up... Here is my twist... I would actualy not run radflo's shock in my configuration. I have to keep a conventional coil and was thinking more along the lines of adding an airshock in place of the standered nitrogen mono-tube... Maybe a king PR2010 in place of the Bilstein AK7110S.

So am I on the right train of thought here?

-Chris.

There was a post on this topic in Jeep Tech. Guys with leaf springs and coil springs running air shocks. One of those contributors might be able to chime in.

There's no reason you can't do that. It would add a nice progressive feature to your suspension. Do it and report back!

One of the guys in my crew run air shocks and small coil springs he nabbed off of something. Works real well.

Sweet! Sounds like all I have to do then is have a shock cap made with a stud to bolt into the factory shock mountig location and I'll be set.

He's using Mazda miata front coil springs mounted next to his air shocks front and rear. They also help as a swaybar as well as suspension aid. Big improvement on handling.

Sway A Way also makes threaded bodied Air Shocks for this kind of application but they never really took off so they don't even include them in their literature. I think Fox made a few sets back about 8 years ago as well...dunno whatever came of those. Even Walker made some threaded bodies for a few people but those disappeared. That tells me the applications must really be limited or not work as well as people hoped they would. Still, I haven't ever ran something like that but there may be some applications where they make sense.

The fabtech shocks on roger lovells rig were like this. Seemed to ride pretty nice.

From what he told me of his coil spring setup it sounded nice. He set the coils up seperately from the airshock and has the coil nuetral at ride height and retained securely top and bottom, this way it limits/slows droop and helps only a little during compression.

I can see why they would not catch on... I figure that proper tuning will be a nightmare. Most people already don't set air shocks up properly. If you go adding in another variable that will through off the already complex task of seting up air shocks. Most guys would just opt for coilovers. I'm going to try it. I don't figure I'll be ready for testing till next spring. But once I do I'll post up my openion of the setup. I really look forward to seeing how it performs.

I don't need threaded body air shocks... I will be running a progressive rate 2.5" lift coil that has a average spring rate of 158lbs and a King 2.0x10 air shock along side it. This is all going on the front of a MJ to help R&D a new suspension system I have in the works. I can't use the shock to suspend the weight of the vehicle and I want to keep things as close to a stock configuration as posible while still being able to change variables such as spring rate, shock valving and ride hight without buying mounds of unneeded parts. But thanks for the heads up. I origenaly planed to use 7100's or 9100's. But the air shocks offer more variables and tunability. This is why I am going to use them.

I think you'll love the options the air shock creates for you. Good choice!

If you're running a separate air shock, then wouldn't you get the best of all worlds (in your case) and use a bypass airshock???

Yes I would, But at $900 each... thats $3600 vs $1200. I could be using the extra $2400 for better investments. It would be sweet for sure and give one of the most dynamic suspension setups possible. But that could always be an upgrade for later. I have to be somewhat rational. Because though I will jump the truck, and use it for pre-running. The fact is that this is AR. and byond log roads there isn't any place to really open up at. So my pre-running will be in small short track type settings. There are some good MX tracks and the Superlift park is a blast to baja the main roads at... these will be my test sites.
