Well if his realatives are all from Germany I guess it's possible.

I have searched and found conflicting info. From what I deducted from several different sources is that the Taco coils are 420#/in. I think we can take this as factual.

Now, according to the donahue info, they make thier coilovers 30% stiffer than taco stock spring rates and 15% stiffer than tundra stock spring rates (use the same spring). Using MATH, not the seat of my pants and the 420# as the stock Taco spring rate I CALCULATED the donahue spring rate to be 546#/in. Now take that and divide by 1.15 and you get the STOCK TUNDRA SPRING RATE AT 475#/IN.

Go figure...

420#/in * 1.30 (30% stiffer) = 546#/in
546#/in / 1.15 (same spring but only 15% stiffer for Tundra) = 474.78#/in


Also, we KNOW that the 1999/2000 V6 4wd coils will lift a stock V6 4WD Taco by about an inch just by swapping the 4runner springs over. Supposedly, the lengths are the same, so the runner springs must have a higher spring rate to give the lift. I know the Tundra setup is stiffer than my original setup, but I also went to the HD struts, so I can't compare apples to apples here w/ the stock suspension. Also at the same time, I lost about 50# worth of brush guard, throwing another kink in the seat-o-the-pants meter.

I personally think the combination of the N91s and the 882's is a much stiffer feel than the tundra v8 coils and the bilstein HD's, but since the struts are different, we run into the same problem w/ the apples to apples comparison, so who knows if the 882's are actually THAT much stiffer. All I know is the PACKAGE of the 882's an n91s' compared to the V8 coils, cornfed 2.5" spacer and bilstein HD struts is NOTICEABLY different on the road under typical driving conditions.

Good calculations. I'm willing to bet that 500 number for the 881 family is really alot higher.

Those things are really stiff. Any spring will compress under a heavy load, but mine compress under light loads, there is the difference.

Tundra coils and spacers is where I place my bet.

Speaking of which, aside from skid plate clearance, is it feasible to drop the diff more than 1" ? Why not 1.5-2" and get those CV's nice and flat again? (esp. if I do a 3" lift)

bamachem

I'll take a pic of mine later today and post it tonight. I have the 1" diff drop in and mine are almost flat. You could easily do 1.5", but I don't see the need.

sschaefer3

There is a crossmember in the way, if you go more than 1".

RTdawgs

the 882s are not only stiffer than the Tundra coils, they are longer, so i understand the harsh differences.

I still would like the lengths of all these coils, i would like to compare to the OMEs.

ErikB

I guess thats what I needed to know. Thanks.

bamachem

The extra length of the OME's shouldn't make them any more stiff. I have about 1/2" more lift w/ the Tundra/Cornfeds than w/ the 882's.

Call some local toyota dealers and see if they have some Tundra Coils on the shelf and see if they will take measurements for you. For me to do it would mean taking the front suspension out and apart, and that isn't going to happen unless I change spacer configuration.

For the OME's, you can call ARBUSA for the 880's, 881's, and 882's. Brian posted on an old thread the dim's of his 882/891s... or maybe it was his 881/891's before he switched. Anyway, you can look that one up.

You're more than welcome to drive over w/ a coil compressor while I sit back and enjoy some suds and watch you take them apart and put them back together, but for some reason, I think that would be going a little too far to get measurements...

Good luck getting the info out of a dealer. Also look on ebay and tundrasolutions. Maybe you can find someone w/ some for sale that could take some "credible" measurements.

Where did you get the Bilstein shock boots from??? Are they sold seperately?
Oh i just looked at your site and found the part numbers

Bighead

I just skimmed over the previous posts. I'll look at them more closely later.

Steve: I understand you are talking about using the 4WD Tundra V8 coils with the Franks spacers (1.5" Cornfed and Revtek). Are you saying use that with OME N91S or Andy's Tundra HD Billies?

I wouldn't mind trying it out, I just don't know if I'll have the time before Moab (I am leaving NC ~22 Sep). Cornfed is out of town and, according to the TTORA boards, his orders are stacking up so it may take a while for spacers. I have to go buy some more balljoint boots at the dealership tomorrow so I will check on some prices for the Tundra coils while I am there. Andy: what is the part number(s) for the Tundra coils?

Hell, I still need to figure out how to make my M8000 fit in my T-15 with my TRD tranny cooler in the way (if anyone has figured out this puzzle please PM with some hints).

sschaefer3

Tundra V8 coils, OME N91S, Cornbred 1.5" and Revtek top out.

Just like mine, 1 engine higher.

azrain

According to the email I received today, Cornfed ain't doing jack for new orders... Wouldn't take my order for some custom stuff, albeit very nicely, apparently there are some life changes going on there.

COYOTA $x$

https://www.1sttoyotaparts.com/partscat.html

has some tundra coils 4wd w and w/o Off Road Package to choose from

70-80$ a piece.


Boy am I lucky, Cornfed accepted my PayPal payment a couple days ago, so that better mean I got real lucky and theyre gonna get my spacers out to me

bamachem

Mine are the TRD Bilsteins for the Tundra. Red Ivan Stewart Ones w/a TRD sticker (Black Letters) on the bottom near the lower eye. You can barely make it out in the pic a few posts above.

[edit] Lookie what I just found...

http://www.wheelersoffroad.com/trd.htm

Red Ivan Stewart Billies are $194.50 a pair

Yellow HD Billies (Same, just not RED) are $134.50 a pair

TRD Tundra Coils are $219.00 a pair

I got VERY lucky and got my complete front set off of eBay as takeoffs on a new 2004 for something like $140 or $150 shipped. That was for the complete front coilpacks. I simply took off the top plate and added the cornfed spacer so it would fit the upper strut mount of the 4runner AND give me lift at the same time.

WOW. Do you think it was from the huge backlog or is he getting out of the business???

How about replacing the 891s with 890s for a softer back?

And does anyone know the part #s for the revtek topout spacers and the studs? My local shop is pricing all the pieces out for me and this is a gray area to him, need to make sure it is right..

Steve - check your pm from yesterday, I need to order up a diff drop asap!

I think the 891's are fine, it's the front 881 family that I personally really don't care for.

Revtek:

Aluminum top spacers: TOE-2
Studs: STD-6

Phone: 1-877-LIFT-TOY (543-8869)


My PM box was full your message did not go through. It's always best to e-mail me through my fastq e-mail address:

sschaefer@fastq.com

I have the steel cylinder and all the hardware for the spacers, I can have them out to you in a day or two no problem.

Bighead

I'm happy with the 891s with the amount of weight I have on/in the rear of my Runner. If anything I may have to add a spacer. I toyed with the idea of going to 892s but I figure I'll try a .5"-1" rear Cornfed before I go that route.

azrain

No clue, didn't push it. I can run a mill and lathe as well, just being lazy. In the end though, I'm just happy to be doing a few things to the junk pile lately, keeps the interest in it when you do a few little tweaky things to see if it works or not.

Mike

Lance - would you recommend the 891s over the 890s if I do not run extra weight in the back, or tow for that matter? I mean the occasional lumber yard haul but nothing regularly back there.
