880/960 OME coils or 1999 OEM coils

[01thunder]

being that i haven't found nor can i find tundra coils, and have a set of beautiful 5100's sitting here, what will a pair of 880's or 881's do for me? i have seen some photos of rigs with the 906/880 combo that looks pretty level. are the 881's going to give me a taller front over the rear? anyone have 881/906 combo and follow that with pics to see?

Im in the same predicament with these two lifts. Here for pics and info

I'm in a similar situation as you, trying to decide what option to go with. I haven't been lucky in finding Tundra coils either. Right now I'm leaning towards OME 881/906, and then adding some trim packers (spacers) to the rear if I get any reverse rake. But then I think maybe I should just go with the 890's in the rear, but sometimes I think pics with that setup look too high in the back. I want to stick with the 265/75R16 tires I currently run on my '98.

If you want pics, use google and do a search on "4Runner OME 881/906" and you will get lots of hits, on this forum and others.

As one example, this guy is running the 881/906, with two sets of 10mm spacers on each side in the rear:

According to this: http://www.arbusa.com/Uploads/PDF/onlineManualsGuides/OME_Guide_current.pdf

The 881 is 10mm taller than the 880. They both have a spring rate of 500lbf/in.

With my 880/906, the rears were ~.5" taller than the front, so if you go with the 881's that are 10mm (.393"), then the difference becomes .107" taller in the rear, so effectively, it becomes level while UNLOADED.

I recently installed an OME 10mm packer on each rear spring, and now my 880/906 has a perfect, noticeable, but not too aggressive rake. Very happy with this combo.

Also, because knowing this would have really helped me out when selecting rear springs:

OE spring rate - 150lbf/in
890 spring rate - 190lbf/in
891 spring rate - 210lbf/in
906 spring rate - 220lbf/in

That's not quite true, remember due to the geometry of the front suspension, adding a taller spring or spacer equates to a lift gain of about 1.5-2.0x the increased coil height or spacer height. So the 881s will probably give you 15-20mm additional lift over the 880s.

mmm, are you sure?

I thought this was only true if you are lifting with a TOP Plate spacer. For example, the top plate spacer here: Front Top Plate Spacer (One - 1/4") is only 1/4" thick, but they state that it gives a 1/2" lift. Also, the coil spring packer here: OME Trim Packer is 5mm thick, and lifts by 5mm.

However, if you look at the COIL Spacer here: Front 2" Lift Spacers it looks like it is actually 2" thick, for 2" of lift.

So if the spring is taller, then isn't that the same thing as having a coil spacer?

I would appreciate being corrected if my understanding is off.

It is my understanding that it does not matter if it is a topout or internal spacer, the same geometry applies. The pictures and descriptions of those various products can be deceiving. That toytec spacer looks about 1" thick to me (only the larger diameter section provides the lift; the other section fits inside the spring).

finished the suspension build today and this is how she looks. 906/billies in back. and since i didn't find any tundra coils, 5100's/stockers with perch in 4th groove. when i do get them, i will swap. i like the way it looks and handles. definite props to everyone here for their input and help.

Are your 5100s for a 4Runner or a Tundra?

tundra. they are not available for a runner. 5100's for tundras and tacos. tundras have 5 grooves, tacos 3, that are used for adjusting the spring perch.

How do you find the stock front springs WITH the Tundra billies on the 4th setting? Does that put a compounding/constraint on the spring and make it less flexible or something like that? (0 setting VS. 5th setting kind of thing)
