No, but you did ask for the link;)
 
I have a 1999 with 863's......I used to have 864's which were way too stiff...
 
Blast from the past...

Are the 2863 and 2864 3" lifts with different sprint rates?

But, I'm a bit confused with the table from post #1 that has the 2864 as 1.5" lift. Or that's just for the older 100 Series?

At the risk of being wrong. I don't see how a 2864 can be a 1.5" lift on any 100. It's the same length as the 863, it just has slightly thicker bar and a higher spring rate. I have them on mine and even with the torsion bars maxed (with droop) I get a little more rake than I want without my full set of summer gear (tent, fridge etc), and that's with a steel bumper and roof rack and spare.

What are your measurements hub to fender?

Don't follow the table. Find the ome spring rate chart. If you compair 863 and 864 you'll see they are the same height, but the 864s have a higher spring rate. Used to run 2863s, drawers, bumper, dual swingouts with 3 Jerry cans, drawers. Got about 2 inches. Was going to switch to 2864s but I wasn't always that loaded up. So I went with TD tourflex progressive heavies

My truck is actually at the shop, so I can't check for you, but the front is at 21.75 and the rear is a good deal higher so there is an inch or two rake.

The first key is forget about lift height. There are way to many factors to say that a coil will give you X" of lift. Focus on the spring rate and experiences from members here.

I run a dobinsons rear with a full size 315 spare, 2 jerry cans, and a hi lift, plus a Dissent roof rack, WKOR sliders, and I run 863's. The 863's are a hair tall unloaded but are perfect when loaded up for a solo trip. I am looking to build some drawers soon and keep more tools with me and that may be reason enough to go to the 864. I havent measured recently but unloaded my hub to fender is ~23-23.5" in the rear.

Me neither... That's why I asked. It seemed odd that the ARB chart would mention that.

I was under the impression that was an ARB chart.

I have a RTT and drawers now. I'm planning to get the rear bumper at some point and don't want to get the wrong springs.

Thanks for your help guys.

I'm not overly worried about some exact amount of height, i'm, just saying that I don't think there are any applications where the 864 only generates 1.5 " of lift in a 100 series. Fully loaded, without extra water, my truck is over 7,000# with just me in it and even then it's more than 1.5" of lift. I just think the chart is wrong.
 
Ok so I am confused... according to Alita's records, she has 865s on her with a 1.5" lift. Wondering if that is part of the reason she is so stiff? She is completely stock other than 285s and sliders, so no heavy bits added.

865s are a relatively light spring, and probably around 1.5 or so of lift. They shouldn't be overly stiff
 
Ok thanks @4Beast ... Was trying to find the aforementioned chart on the ARB USA website but it just keeps reloading the page for me.
Can someone link to it?

The 865 are stock to light with 1.5" lift.

Yes. They have a problem with that site.

I put it in the first page, around post 3

Should have clarified. Dont go off the "lift height column" in the first chart.. Go by spring rate and length in @4Beast post. Youll see the 863 and 864s are the same except 864s have a higher spring rate, which will yield a higher lift with the same weight. My recommendation. Go with the 863s but install Air bags (airlift 1000). Thatll help "future proof" any additional future weight.

Another source for spring rates
 
Ive maxed out the rate on my Ironman TOY13B springs with my build and looking for an option that will get rear height back up close to 23" hub center to fend lip height.

The Ironman TOY13B is a "performance coil" for loads from 0-220 kg ~40Nm spring rate 18mm coil 485/495mm free height- when I first installed them before the rear bumper and sliders my rear hub center to fender edge measurement was closer 23.5" . Later adding rear bumper & swing outs, sliders, drawers and fridge Ive lost some height and measuring 22,25 & 22.5 with a static load now closer to 450-500lbs.

So my next move is to go up a step on springs. Theres a few OME to consider, as well as some others. For those with set up similar to mine ( rear bumper & swing outs, sliders, drawers and fridge) running 2863 or another spring- what are your current hub center to fender edge measurements?

@atnolan94 What are your current measurements with the 863's we have similar set ups.

Here a comparison list I've started to put together:

I’m at 23.5-24ish. But in discussing with @ga12r1 I believe I have a 30mm trim packer in there. I can’t remember if I threw them in or not and I’m not about to lay on my back to look. So an 863 with my setup would net you around 23.
