Ack, if I had the time this weekend I could measure on the LR3. Maybe sometime this week.
"Also, neat idea I've seen before, just to spur some extra creativity.... Rock slider nerf bar air tanks, with hose connections for tire filling"
I LOVE this idea. Idk how much volume you could get out of it, but for an application like this it could work out well! I thought it would be sick to close up the frame and make it the air tank, but that's just asking for rust from the moist air. You could also put a drier before the tank and make it work. I'm actually test fitting an air chuck on the front an rear of the car that way I can use a shorter hose compared to a long hose. A guy I know made an elaborate system that auto inflates each tire to a specified PSI. All he has to do is hook up the 4 short air hoses he made and press a button. He'll walk around and chat with us while were squatting or kneeling on the ground watching a pressure gauge. To make it sufficient for filling up tires on a regular basis, get a higher CFM one than the HF one. It literally took me 30 minutes to air up 4 tires with the compressor, and it got REAL hot. I doubt it could do it more than 3 times. I'll have to do a write up when I do my on board air system.

Could try sourcing used compressors with a better duty cycle on Marketplace or the like to save a few bucks. The HF stuff will not be a 100% duty cycle, as far as I know? Compressors meant for air suspension can handle a lot more volume for a lot longer without overheating or failure. And the PVC for a tank thing would be a no go for me, specially not in the Colorado cold temperatures... that'd make for one heck of a bomb, lol
Wow! I severely underestimated how much volume was inside the frame. Air tank volume can help air up tires faster, but not by a whole lot. In my system (2 gallon tank at 120psi, to fill up 35 ft^3 from 10-40 psi) it saves 30ish seconds overall according to my napkin math. You can start the air compressor before you air up and build up some pressure, so you start with X psi over 0 psi in the system. When switching from airing up one tire to another you can build up some pressure too, but it won't be a whole lot. But ofc that's with 2 gallons, not 8-10.The reason I'm including it is to help set beads. As I'm switching from CO2 ($$$ to refill, and takes up a lot of interior space), to dust stuff off at camp, and to run a train horn. I used to have 4 quick connects and 4 small hoses, one to each tire. But because of the different length air lines each would fill up at a different pace, and I'd have to let it sit to equal out. Not to mention having to store 4 hoses instead of 1. Now I designed and built that system when I was in high school, and have learned since.
I'd build this system to me modular, so you can add or remove components easily and build off of it.

Also, just something to consider, while an air suspension system can also be used as a tire fill system, the reverse is not true. Air suspension runs at around 200 psi, an onboard air system will usually run much lower pressures around 120-150 max. This also makes a big difference in the style of compressor that is used for air suspension.

Hey guys, thanks for all the information. I'm glad to hear folks are already thinking about this, so I'm not the only crazy one.
I've been chatting with the guys at Arnott about components about some of their options. They're willing to help, but had a couple of questions:

- Overall length of loaded shock assembly. (front and rear, I suppose)
- Spring Rate.

Found a link to the spring rates for Land Rover vehicles, should be helpful, loads of info:
land rover spring specifications
And this link should be helpful for basic shock lengths for the D2:
https://www.aulro.com/afvb/discovery...ngth-list.html
Although, the front shocks may be more akin to the P38 lengths once we modify the front shocks mounts with the R.A.C. Twister kit. RAC should be able to say what shock length would work best with their kit, but for starters, I found this info for the P38 basic OE specs:
P38 std shocks
front - 534mm open, 337mm closed (21", 13.2")
rear - 475mm open, 311mm closed (18.7", 12.2")

I got a reply back from R.A.C. tonight. They say they will put together some info on their kit and post it here, as well as letting me know others have used their kit to add air suspension to the Disco, and that it has been done successfully. So, good news... gettin closer

100th Monkey effect...in effect, lol
Looks like the European guys are sharing some pretty useful and promising info on FB. Seems to be yet another one of those commonplace mods over there, that we are just gettin on board with. There's a thread in the "Discovery 2 Owners Club" on FB, LOTS of good info...
Happy Modding !
