Copy that. I checked the pressures, then bled them off. One had 100 psi. The other zero, but there is pressure trapped in the body. I think some N2 got past the IFP. Dispite pulling the valve core, pressure is still pushing the shaft out.
They are all like that. Have lots of rags handy if plan on taking them apart. And maybe a hazmat suit.

Thanks. This is my first shock rebuild. LOL
I have some old sway-a-way 2.0 coilovers I should practice on..
AND.. I have Fabtech 2.25 I will run on the rear. My coworker gave me these. I got rebuild kits for them also, from Kris. Screenshot_20200319-101857_LINE_1584746439104.jpg

And in Fabtech's defense. They don't claim a stainless body, I misunderstood. :-( Screenshot_20200320-180841_YouTube_1584746554381.jpg

I had a small email chat with him. He confessed to working at Fabtech for 10 years. 😄

I got my shocks in today 😬 (used)... they are fucking huge. Spring ID is 4.7". 🤯.
They calm they are stainless bodies... bitch please. Stainless coating maybe.. I buffed it with a wire wheel. I will paint the resi and shock body below the treads. View attachment 2969064

You could look into stock car coil springs from Speedway Motors or similar. Not sure on their exact ID, but I do know 5” and 5.5” OD are common and tons of spring rates and lengths are available across multiple brands.

Not to thread jack, but what are the extended and compressed measurements on these in your 8" lift flavour? I saw a set locally for $500 and I'm tempted to snatch them up.

Sorry for the late reply. I missed this.
It is hard to be exact because the heims are moving, but basically 28-1/4" extended to 19-1/4" collapsed. That's center eye to center eye.
Also.. when I called fabtech the rep I talked to told me I have the 6" coilover, but there website says I have the 8".. WTF..

Also.. the stock coilover mounting width is 2", and the misalignment bushing they use is trash. I tossed them and got some stainless ones.
Most off the shelf coilover mounts are 1.5" to 1.75". So I had to make the mounts also.

I'd be very surprised if he can't find an OEM spring that fits his needs. Modern cars run some pretty long springs in the name of ride quality.

Length isn't the problem. It's the ID. 4.7" ID. 350 to 400 LBS/Inch. I need to drop the truck on these springs to get an accurate assessment.

Thanks, no worries on the late reply. I actually emailed Fabtech today and the rep told me there's no difference between the 8" and 10" versions, they just use a different lower mount in their lift kits. Here's the lengths per Fabtech:

FABFTS835012 8" coilover
EXT 28.3”
Compressed 19.25”

if you want to run a dual rate, i ran into the same problem on my 10" stroke shocks for my cantilever.

I made a slider with one end longer than the other. the longer end sits inside the top spring between the shock body and the ID of the top spring. The longer side will alow the top spring to compress then hit the it hits the top slider. adjustment is a bit shitty, i machined the slider down to let the top spring have more travel little by little until i got what i wanted.

So.. I have the truck on the springs. I had to put the resivior to the front because the damn AC until is in the way on the passenger side. I have a lot more work to do.
That's a factory height F250 with 35'S.
