Yes, taller free length for sure. They will probably be taller under load as well. I have the free length specs for them somewhere if you need.

Yes, the 700 lb coils are going to ride taller than the OME J. A friend is running them and the rig was certainly taller compared to mine with the J springs.
I would make sure of your part numbers before you order. Last I checked the progressive coils in 3-4" range weren't up on Amazon. The ones you looked at might be linear. A quick email to @David Otero will get you the right thing first time around.
Also, this might be helpful - I went back and forth on whether or not to run a different length front and rear. Similar to the level stance you get by using an OME 850J but regular 863 rear. In the end we decided to run the 3'' all the way around and the truck sits almost perfectly level.
Thanks for the heads up. yeah the ones on amazon are linear. I deleted them outta my cart! Can you post a pic of your rig? What size tires? I am running 37's now. Works well with the J's
Also as of now I am running a 1" spacer in the front to level out the J's. I do not want to lift the front anymore. I am already not satisfied with my castor #'s now so I don't want to have to lift the front even more to match a higher rear. I was planning on leaving the front j's and spacer up front and just replace the rear coils. I have added rear drawers (130#), plus stuff in box (100#) Rear fridge (30#) Rear bumper with carrier (250#). So right around 510#. So trying to keep the same height should I go 3" or 4" thats the question.
Thanks for the help on this.
@scrowley I don't want to clutter up the op's thread with my springs. Here is the link over to the 3'' review and you will be able to see my current setup. Or my build thread is at the bottom of my sig. More pictures in the other thread coming soon. Dobinsons 3 inch Progressive / Flexi coil review hope this helps.
@Bad80 what weight do you have in the rear of the 80 and what do you think of the ride?

The weight on the rear of the 80 is about 300lb. I'm trying to get some measurements with specific weights so you guys can see how high it will ride according to different loads. The truck feels more stable than before. It doesn't lean as much as it used to with the J springs,making it feel more planted on the road. There is no wondering of any kind and I don't feel any type of transition between the spring rates on the coil. It is very smooth

If you measure the distance from the center of the hub to the top of the fender, you can compare it to what I have posted and see if it is close to what you have
That's great to hear. My 4" coils should be here tomorrow.
I found out real quick that I need a spring compressor or I could fight with the Fox shocks again.

I did mine without spring compressors, It wasn't hard to do at all. Disconnect the shocks, sway bars, the rear proportioning valve arm at the axle, and the brake lines from the chassis mount and let the axle drop. I had a friend stand on the axle end to push it down while I got the coils in. About 1 hr per axle with air tools (FL truck with no rust)
I left the wheels on the axle but only lifted one side at a time. I used the spring compressor to get them in. It took about 45 minutes from start to finish.
Pulling out of the driveway last night with the new coils installed and the rear felt mushy and bouncy. After 1 mile, the coils were starting to settle in and the ride became more stable. I also noticed that my rear is leaning quite badly to the drivers side. I installed the springs per the label, left (driver) and right (passenger). I hope that after a week the distance between driver and passenger heights are closer.
Driving to work this morning and the springs felt great. The rear end felt both compliant and stable over bumps. The only issue I had was when I took a tight corkscrew onramp, the truck was leaning quite a bit to the driver's side.
Dobinson has trim packers and spacers that will fix your lean.
Are both of your anti-sway bars installed with good bushings?
What shocks are you running? How old are they?
How about some good pics showing stance, tire to fender distance, and what your 80 has bolted to it in the way of extra weight.
I really don't want to go higher with trim packers on the truck. The previous springs were "3.5 lift" springs The Dobinson 4" springs lifted the truck a lot more than I expected.
Sway bar is installed. The swaybar moves freely in the bushings and the bushing are ok shape.
The shocks are new Fox 2.0 Performance shocks for 3" to 5" lift.
I will get pictures with the truck on a level surface.
