Update,
I got the steel today, chromoly
4140 should be nice and strong

1.5" is too short, not enough steel
in that length to keep the strength
2" is as short as they can be made
and keep product integrity

Sorry
Wild

I'd go for whatever is necessary for a 2" lift.  I'm less worried about max extension with it than having it too long and bottoming the shaft out on compression.

No, 2-1/2" of length, the front is a compound
ratio, 2" at the spring is 3" at the wheel, but
the CVs can't take 3" without moving the axle
housing down, so 2-1/2" it is for CV life

Also, no upper mount flip is needed with these

Ok, I did not read this post carefully enough.  The 2.5" strut spacer helps the CV's when there is a 2" spring spacer.  If you get 3" lift at the wheel on the front, since you have a straight axle in the rear, will a 2" spring spacer in the rear only give you 2" at the wheel? meaning you will need a 3" spacer in the rear to match the 3" of lift at the wheel in the front?  I know the crown vic shocks are 1.5" longer, but are they long enough for a 3" lift?
My rear is slightly higher than the front, but I like it that way, because when I fill the thing with people and junk, the hitch hits more on the trail, so maybe the rear squats with added weight. 
Thanks

since you have a straight axle in the rear, will a 2"
spring spacer in the rear only give you 2" at the wheel?

Yes, the rear is a 1:1 lift ratio

I know the crown vic shocks are 1.5" longer,
but are they long enough for a 3" lift?

Yes, unlike the lift spacers at the springs, the
shocks are inboard, which creates a ratio of
the movement, I have 3" rear spring spacers
in the rear, and I run Crown Vic shocks, at full
droop, the spring is just loose enough to move
(rattle) around

You want 2-1/2" front strut extensions to match
your rear, and keep the rear slightly higher

Ok so is it really that easy to get 3" of suspension lift?  what about that thingy-ma -bob that hangs on to the top of the rear diff? can that handle the lift? In your other post you said 2" lift for about $150.  That would be the same for 3" of lift? Amazing!
I know you wont get the same results as the calmini super articulation 3" suspension lift, but this is way less money. 

what about that thingy-ma -bob that hangs on to
the top of the rear diff? can that handle the lift?

It's really at it's limit with 3" in the rear, I built a rear
upper A-arm spacer to get the LSPV to work correctly.

Do you have a picture of that?
whats a LSPV?

LSPV is the load sensing proportioning valve, not
all came with it, I belive the models with ABS do not
have this

Here is the rear A-arm spacer, it also rotates the axle for
bigger tire clearance and better driveshaft angle

ok, i'm still interested in the 2inch extensions

Just for everyone's info about the coil spacers;

The cost of the material has risen dramatically. Almost double what I started out paying for it. Because of this it has started to become not financially worth it anymore for me to sell them for the cheap price I had on them before. Also Sky has now invested in a poly machine, so they can actually make them cheaper than I can now. I only have a couple sets left and they are going to be listed on ebay. Once they are gone, I'm probably not going to be making any more unless the price of UHMW comes back down.

If anyone is interested, I plan on making at least one custom 2" set that would include two 1-1/2" spacers for the front and four 1" spacers for the rear(2 per side, screwed together to make a solid 2" spacer for each side). This would lift the vehicle at least 2" all around, would make good use of the strut spacers spoken of in this thread and would work well with the Crown Vic shocks. The cost of this custom spacer set from me would be $80 shipped for the spacers, rear rubber isolator centering rings and full instructions. You would have to get your own strut spacers/extensions and shocks.

Like I said, I'm almost out and done making them, so if anyone is interested, let me know asap! SnakebiteEMS|removethispart|@hotmail.com

Aww man Digger, I hoped this would
boost your spacer business    I have
been posting for people to contact you
for their spacer needs.

I really do appreciate it, it's just the price of the material is going up so high so fast that I would have to start charging the same as the name brand places just to come out ahead at all. If I can find a cheaper place to get the material from, I will, but until then I am going to have to slow down for a while...

I still have a bunch of spring spacers & strut spacers avalible if you guys are not going to be making them .  stan

dumb question here//  so if you put these strut spacers in does it give you more lift or does it just give the strut more travel? just wondering  cuz i just finished putting diggers  1.5 spacers in and got it all aligned and all that fun stuff.. just don't reallt want to do it again if i don't have to..lol( )

Hey Wild, what kind of suspension and tires are you running.  Do you have these extensions on your kick or are you running OME's or a strut flip?  Alos, got any pics?  The only pics of the turbo Kick I've seen are the underhood shots on your web page and your icon.
