I don't think anyone really objects to the 891. It is a good spring.

 

*** Ok, does anyone know the difference between the Tundra "off-road" package spring and the standard spring?

Is one progressive and one not? What are they?

 

Or if theres a difference between the 2Wd offroad package front coil and the 4Wd offroad package front coil

and if there a differece in those for double cab vs other models....

ugggh



EDIT: In bettter news, got a call from Cornfedsuspensions, my 1.5" spacers should ship out this coming Monday or Tuesday.... getting closer !

 

Your not going to want ANYTHING from a 2WD, it really boils down to the 4WD, V8 non-off-road or the off-road.

I ordered some stuff from Big Two Toyota, when I go pick it up I'll try to have the parts guy look some stuff up.

But, he's not going to be able to say one is progressive and one is not.

Maybe we should post on Tundra Solutions?

 

I wish I knew EXACTLY what mine are and what they came off of. They aren't progressive-looking like the PP springs. All of the coils are evenly spaced. I'll see if I can look up the guy I bough them from and ask him.

 

what i find is funny, every person on this forum site has totally different info on lift spacers on the tacoma. one piece of info is that going with 3 inch lift spacer in front will kill any articulation, or u call it droop.. or others say 3 inch lift spacer is just fine with on cons. i have made my own Frainkenstein lift spacers, with confidence that they will workthrough research. and really i do not see where their will be no problems, Now as an engineer and drafter, the spacer that is installed in the strut itself, will have a major problem down the road. If you think about it, that added compression on the spring is only gonna make that spring weak faster. And ALL springs get weak with time, so why speed up the process with that style of lift

 

That's one of the problems I have been running into. I have been to 3 dealership parts departments and none of them can tell me the part number info we are looking for. I thought all TRD springs were progressive but I can't get confirmation that's true.

Still looking...

 

FOR REFERENCE:::::::::::::::::::::::::::::::::::::

Just installed the 892s and OME shocks today (Only did the lift in the Rear for the moment). With the Cornfeds shipping out Mon or Tuesday, I figured I could live with the unevenness for a week, and have this portion of the lift install knocked-out.

I only had stock susp. stuff on before and with all the add-on stuff in the rear of the runner, the hind end was sitting lower than the front, not real bad, but I was probably going to have to re-adjust my headlights pretty soon.

the added weight of extra spare, other stuff on the rack, SSF bumper and gear in the cargo area::::
I was sitting at just a smidgeon over 36" on stock susp. after OME install, with all that gear, Im sitting at 39.0"

for additional reference, with no bumper at all and no gear, I was at 37.5"

Current tires for all measurements to date, are bald, boring firestone street tires in 265/76/16

 

Some tundra spring info I found:

2000-2002 Tundra



Stock 4X2 coils
- drivers: yellow-white
- passengers: blue-white

Stock 4X4 coils
- drivers: yellow-green
- passengers: blue-green

TRD 4X2 coils
- drivers: yellow-yellow
- passengers: blue-yellow

TRD 4X4 coils
- drivers: red-yellow
- passengers: purple-yellow

 

Excellent, Here are the questions we are working on now:

1. What is the difference between the Off-Road and the Standard coil. I will try to find one of each of these brand new at the dealer. If I can identify the Off-Road one has progressive coils, it's out.

2. Was any partucular year Tundra taller than the others? IE, the 1999 4Runner being the highest, the 96-97 having truly crappy springs, the 98 having something in the middle and the 01-02 getting the truly crappy springs again. Is one Tundra year better than others?

3. Lets not just look at the Tundra, Accodring to what Robb found out we can look at the Sequoia, Is the Sequoia heavier than the Tundra, like the 3rd Gen 4Runner is heavier than the Tacoma? If so, screw the Tundra lets do Sequoia coils !!!

Bear in mind, the differneces in the coils is going to be very very small. They are factory coils and will have different part numbers for extremly small variances.

So start digging, my parts should be in Monday, my parts guy is the excellent, he'll give me part numbers and help anyway he can, he's a real nice guy.

 

Oooooh! You're all forcing me to hold out on the SAW install!!! Keep the info comin guys.

 

I have been kind of following this thread and found some trd offroad tundra coils on Ebay. check the link. Unfortunately, after reading the color scheme above, these must be the 4x2 off road springs. They are yellow-yellow and yellow-blue. Came with TRD shocks and I never even thought to ask if it was 4x2 or 4x4. Whew, glad I didn't buy them...

From those pics I'd say TRD 4x2 Springs are NOT Progressive.

 

According to the color chart, I have the 4x2 standard coils. So much for getting what's advertised on fleabay.

At least I got the Billies included for what I paid - $140 shipped for the assembled coilpacks.

2WD, 4WD, or whatever, These (with the billies) are more firm and feel better than the stock coils. Now to get info on all 4 coils such as rates and lengths.

 

Let's see some pics of wheel articulation. Maybe the 4x2 springs are doable for the 3rd gen runner. Sounded like you really liked your setup. I'm not totally opposed to the 4x2 Tundra springs if they can adequately be Frankensteined.

 

Will Do. I'll work on getting some and post them. Might take a day or so though.

 

FEI,

I asked the seller, they are from a v8, 4x2 double cab "pre Runner" (his words not mine)

 

OK, I got the parts guy to look up all the springs. Very very interesting.

Here you go:

1999 4Runner, V6, 4WD, 16" wheels:
48131-35400
368mm

2004 Tundra, V8, 4WD:
48131-AF310
363.5mm

2004 Sequoia, V8, 4WD:
48131-AF120
380mm

So what this means is that the Tundra coils are SHORTER than the 1999 4RUNNER coils !!!

Hence andy's 2.5" of lift with a 2.5" spacer, my spider sence is that the Tundra coils he has are basically the exact same as a stock 4Runner coil or even a bit less.

THE WINNER IS, Sequoia Coils.

Left Side: 48131-AF120 @ 380mm
Right Side: 48131-AF110 @ 372mm

This makes perfect sence, replaceing SUV coils with a larger SUV's coils. V6 up to a V8.

There you go boys. That's it. End of the story. Order them up. Standard coils, not progressive and will fit the 4Runner strut pack perfectly.

 

interesting all right. 2.54cm per inch, 25.4mm per inch.... 12mm between Sequoia and 99 4Runner = ~1/2 inch difference in total length.


What about spring rate though ? No effect ? Before we were talking like that was a significant influence ?

 

Based on what I actually saw on the Parts computer, it looks like all the lenght is an extremely important number. My gut feeling is that all the stock coils are the same wire, just wound at different lengths. Think about it, that would be cheaper to make, buy a roll of wire and wind them for the specific truck, hence all the different part number for the small variance.

Want to prove it? Get the coil diameter of a Sequoia, Tundra, Tacoma and 3rd Gen 4Runner.

The Tundra, Sequoia, 3rd Gen 4Runner and 95.5 to 04 Tacoma all have the same strut family.

It makes sence.
