No. The 08 coils basically give you a 08+ 4wd suspension for lack of a better description. It won't work with a 2" soacer. 1.5" max before you'll notice cbc.

 

So does that mean I do not have to have the bilstiens? I can use stock suspension?

 

look at the pic in my sig.. oem tire size, 32.66666667'' (or whatever it is) that is 5100's on middle perch with 4x4 moog springs, 1.5'' spacer in the rear. if you want higher you'll need a 1.5'' spacer (the limit) to add to the top of the 5100's.

 

My 04 2wd Got 4.5" of lift with 08 4x oem non pro x springs and Bils on 2nd perch. Only .25" of clearance between the UCA and coil bucket on full droop. without the Bils id assume you'd 3.5" from the springs alone.
Heres my thread- http://www.titantalk.com/forums/titan-suspension/286330-better-late-than-never.html

 

Only way you'd get 4" from the springs is if you had completely destroyed shocks and didn't account for it when you measured.

 

Either that or camber is out of wack...

I got between 3.5"-4.0".

 

The 04 XE 2wd sat 1" lower than the SE 2wd. Maybe that's why?
This is the thread that got me to drop 90.00 on springs and 210.00 on Bils, to fit those tires on my truck!

Here's a quote from that thread
After giving it a little thought (hopefully I have it correct), I can see a 2wd getting 5". The 08 4x4 springs level an older 4x4 at 2" (1" due to a longer spring and 1" due to a stiffer spring). A stock 4x4 sits about an inch higher than a 2wd truck. So the 08 4x4 springs will lift a 2wd truck roughly 3" without taking into account the weight of the truck. Now, knowing that a 4x4 is a few hundred pounds heavier than 2wd (and all that weight is mostly in the front) then an extra 1" with the 5100's on the lowest setting seems pretty reasonable on a 2wd. So we're at 4" now. So 5" at the middle setting seems like it is possible. I don't know what will happen with the coil bucket contact situation with 5" of lift. Hopefully I didn't miss anything and have the numbers correct

Before/After

 

I can NOT afford bilstiens. Way too expensive for me.. Can I manage to use stock suspension with the 08+ 4x4 springs?

 

Save your money, the labor to put the springs in is the same as for the shocks... I paid 210.00 for the pair shipped on amazon Prime.
Not worth going through all that work not to them at the same time. don't forget you'll need an alignment either way.

 

Ok. Thanks for the advice. Like I said I'm new to all of this. Which bilstien 5100 do I need? Just need some direction.
