Should jam down to Harbor Freight for one of their 3ton long reach models
Sorry it’s not going smoothly, but glad you weren’t hurt by flying coils

Well, woke up, decided id do the slee mounts while i waited for the coil clamps due by 10PM.
Fender liners out, around 11, truck pulls up with the overnight goods. LOL
ANYYYYWAY. Ive got some good stuff going on with my group 31 and on air compressor.
Here it is, im getting lazy, and dont feel like writing stuff on the computer on saturday. But ask and we shall be answered from my phone later.
I got really creative with this one, and planned it out well, and its gonna be ****ing sick.
Both fender liners yeeted.
heheh
just one cut to the slee 2nd tray, and itll be bolted underneath here, and this compressor is DROP IN and clamped. Finesse ...
Can anyone recommend the best way to hardwire this with a switch or something though? I know theres tons of info all over MUD, but i want to ask here.
BTW rough edges on everything SLEE, very unimpressed with these expensive 1 day R&D brackets.

I put these hoes in time out.
Here you can see how much further the collar sits and how much load there really is to get it back to stock length assembled.
Im gonna swap L and R too, get the right fresher spring and shock some of my heavy weight driver seat loving. With that heavy ass battery, and the brake system, and steering column all on top of it.
BTW I decided I'm indeed lifting 2". I want N to be what H was, will watch cv angles and dial in and level of course with the laptop.

Silly question, but are you running the Westcott 200 series front and rear spacers?

Yes, in addition to a cheapy 20mm i had up front before.

And its in.
Few cuts in the right places, removed unused bracketing. And bam.
The fit is almost perfect. By my standards perfect.
Just need to get some metal riser spacers instead of the plastic temporary fittings i put on but its solid as can be.
Its removable, servicable, and mobile as it sits with the batttery leads. Need to come up with a clean solution for permanent cabling.
But IDK. No-one chimed in.
Also, I dropped a locking nut in the front of the secondary cooler box on the left here and its gone.
Black hole gone. I have a borescope and everything. I think its wedged between the foam and crash bar.
Its driving me nut.

If anyones still reading, my "27.5mm stack" probably compresses to 25mm given the minimal 34 lb-ft torque spec.
I have plenty of stud engagement BUT, for tomorrows problem, I'm test fitting today and it is indeed the case the AHC hose bracket does not meet.
This assembly below fits perfectly into the bucket, but the stand off hose attachment bracket is like 2mm beneath the buckets top hole bore.
I put the angle grinder to it and will take some more photos once i round off the hose attacher to be able to sit inside that flange.
@TeCKis300 i believe you've been here for your 20mm? Good info for those who dont want to hack stuff up, although its not a big deal at all.
) 10mm oem = drop in, no stud lengthening, no ahc hose clamp mod
) 15mm = stud lengthening, ahc still clamps sealed to the isolator it bolts to
) 20mm and above = mod both studs and the ahc hose fitment flange mod
I decided to go rubber, metal, rubber, metal.
Ill write up more bs once im done trying to get the courage to compress those coils again.
The new style locking clamp compressors seem promising, but im going to do it outside this time with some more protection.

What im hoping to learn after this is installed, is the true motion ratio of the IFS.
I measured 23 drooped when bolted up before, and i am adding only 7.5mm to the top.
Whatever MMs my hub droops further from there, should equal additional travel, and reveal how muhc 7.5 in shock motion, relates to the wheel through the arms.

Have you seen an unmodified droop measurement anywhere?

Lol no, thats part of the problem.
The Westcott spacer measures 12.8mm, or I’d guess they call it 13mm and since they don’t include longer studs, I guess they also expect that is the thickest you can use on factory studs? I would, however, be a little more comfortable with longer studs even on the Westcott spacer despite there being a tiny bit of the factory stud sticking up out of the nut.

I am super dumb i have no idea why that 7.5mm was stuck in my head. I discussed with westcott during measurements and i think that was misquoted….
I will have to edit all of my references to that.
Just measured it, its 12.5mm.
No wonder the stack looked so tall.
I guess ill be at 30mm after compression. Definitely will have to lift more.
Or should i just order the T 10mm?
Hmm

Ok, got a bit concerned my plans were shot after your comment @MTKID so thank you!
I have since found my mistake. Of all things to not measure...
I was never on 20mm spacers... I was on 15mm...
I returned the 20s out of precaution for over-compression 6 months ago when i bought both to compare stud length.
Now that I'm extending the bump stops as part of the lift kit, and we know there is reserves up top, I'm happy with this once again LOL and will continue on.
My "homework" total is still correct though. 27.5mm
This is where i guess i pulled that 7.5 spec out of my ass. My plan was always 27.5mm top spacing. And i just deduced from my faulty memory what the westcott was.
Glad i decided to take things super slow on this one and do multiple mods to keep busy.
And thanks for the support!

Some more photos comparing thread engagement:
15mm only
27.5mm test fit:
(aka will the ahc hose clamp up)
Were still on track boys!
Just need to deal with the death traps soon. Im calling around the shops in my neighborhood to see if they will take care of me.
But everyone is "super busy". When will 2020 end?

Documented here. Fender to center of hub is 24.5".
Suspension Travel Comparison
Been meaning to do this to get some objective numbers to compare ride height versus droop travel versus compression travel. What better to do on a rainy day. Hope is that others may contribute and I'll update my table. We've known for awhile that some aftermarket suspensions increase what is...
forum.ih8mud.com
That's a really ambitious stack. I think you know that @Killacaviar is backing down to 24mm? I'm not exactly following but I think it's going to be more than you bargained for. Also concerned that with that stack, and the spring pre-load, you'll have too much overall pre-load even for a 2" sensor lift.
If I were to recommend, I think the sweet spot is 18mm - 24mm. With anything beyond ~18mm needing sway bar droop attention.

Thanks teck!
So in reality, the rubber isolator spacer will compress quite a bit, im 27.5mm finger pressed.
That spacer will easily compress the few mm to be in the 25mm overall length probably even less.
If i keep ratcheting on the stud nuts up top, i can keep compressing, and thats why i like the rubber spacer in between, i can get solid bite and some give at the same time. So assuming doubling of wheel motion with 25 ish mm, that puts me right around that 2" overall lift im aiming for.
Unless we know the exact actual motion ratio?
I know i have the 25mm in the shock ram in upwards compression to spare, I can clearly confirm visually where it has never travelled.
But I'm also extending bump stops and since i wont ever be rock crawling this anyway, i should never be in danger zone at full stuff.
I will definitely be doing extended sway links front and back, and the 1" additional sensor lift only at that time.
Im still shopping for those.
I will definitely be over-sprung in the meantime, but this is intentional due to;
A) My need for further personal experimentation and observations at the 1" l ride on currently and how it has improved in damping and control.
B) I need the sway links extended front and rear before i add the lift and crush all my bushings or worse snap/ bend link arms or bolts and crush bushings.
C) I need to Install my now arrived adjustable 4 link arms upper and lower back there
D) Re-adjusting my pan-hard and a true 4 wheel alignment.
E) Finalize the rear travel extension mod solution i like best.
Before all of that is done, the rear does not have enough droop for me to feel comfortable beating on it. Im not trying to go fast and loose on this one.
And those steps above, are another full teardown install for another day.
In regards to your preload issue, maybe im wrong but the preload only sits within the spring collar and OEM top strut plate.
Both top spacers do not contribute to preload on the coil. Just compensates for the additional down travel needed.
Are you concerned that the additional overall strut length will prematurely compress the coil?
I expecting ride control to be soft, and springs to be actuated earlier. Is there something else im missing thoug?
Help is always appreciated.
All for experimenting and breaking new ground so I'm exciting you're pushing the envelop.
Couple thoughts
- Preload - in regards to AHC, both in coil and above coil spacers are going to contribute to pre-load of the coil spring. That's because neutral height is governed by the AHC system rather than falling on the coilovers to find equilibrium.
- It's kind of...interesting that the Wescott above coil spacer is not solid? I'm not sure the stud mount is designed for play there. You'll get some weird noises through the chassis as the stud threads saw against the bucket mount if it's allowed to compress there. I would mount it tightly and not assume it should compress.
