You might want to cancel that order. I'm not kidding. Sonoran Steel is in the production stages of the Frankenstein spacer and with the Sequoia coils, Old Man Emu shocks and Frank spacer, you'll have something INCREDABLE.

When did all of this come about? Thats some QUICK R&D!!!
I have to run the SAW's for at least a little while b/c my OME's are committed to another person and he needs them ASAP. Then I'd have to buy a new OEM top plate and stuff?

 

I think you're forgetting one thing when you compare coil lengths. You're forgetting that the Tundra Coils are 475#/in. We've already proven that. The Taco coils are the SAME DIAMETER are 420#/in. We've proven that too. That means that the coils ARE NOT simply the same wire in different lengths. If the 4Runner coils are 440-450#/in (that will be a good, close estimate since we know they are stiffer than taco coils since 4wd 4runner coils will raise a 4wd taco 1" on a swap), and the Tundra coils are 475#/in, but 1/2" shorter in length, then the Tundra coils would give the same EFFECTIVE height. Let's examine the numbers to verify it. Somebody PLEASE get me the front weight from the VIN sticker on the front of a V8 4x4 Tundra and the same info on the 4x4 Sequoia. I'll do the calcs to compare that to my 4Runner and post the EFFECTIVE HEIGHTS for the Tundra Coils and the Sequoia Coils on the 4Runner.

 

At this point someone needs to get a dial caliper and mesure the thickness of the coil.

For now, I'm throwing all the "Internet Rumors" out. I only want real world , what you did, Not what you heard.

Lets get the diameter of the verious vehicle coils. I'll get a dial calaper and measure the 04, 05's on the dealer lot. If they are the same...........................

or

If they are different, we'll know.

1/2" makes sence. the V6 4Runner coil DOES NOT lift the 2.7 any higher than the 2.7 coil did.

We need real world, boys, not internet.

 

2003 Tundra V8 4X4 TRD:

 

The 420# Number was from 3 different sources. The 475# number was calculated based on Donahue info. They make suspension parts, so I tend to trust the info that I got from them.

I don't have dial calipers, but I'll see what I can do. I would imagine that the 3.4L is maybe 100# heavier than the 2.7L. Do you agree? If so, then w/ a 450#/in spring rate, then there would be less than a 1/4" difference in height. With the higher spring rate and shorter coil, you get the same effective height w/ a slightly stiffer rate. What REALLY needs to be done is to MEASURE the rates of each one. Unfortunately, the only way to do that is using a hydraulic or mechanical press OR to use a DEFINED WEIGHT and measure the deflection on the truck.

What if we got a KNOWN 400-500# and somehow applied it to the front of the truck slightly in front of the front coils (to apply the weight to the front only w/ no moment induced onto the rear coils), then measure the deflections??? Get about 3 of your buddies to stand on your TJM and see how much the 99 coils compress. Get someone to do that with a sequoia, and I can do that w/ the Tundra coils. As long as two variables of the equation are known, then the third can be calculated. Measure the weight w/ bathroom scales (each person) and the amount of deflection, and the result is the spring rate of each coil (w/ strut attached). We know that all three coils are NOT progressive, so the rates are supposed to be constant throughout normal compression range. (Take into account that there are TWO springs up front, so the observed rate will be double the rate for EACH individual coil). You will need to measure the deflection on BOTH sides since you have two springs and the weight won't be distributed perfectly evenly.

(Weight Applied) / (Total Length of Deflection) = (Coil Rate in REAL LIFE)

according to the stickers, the Tundra is 60# HEAVIER in the rear than the Sequoia, but the GVWR is 590# higher for the Sequoia... hmmm...

 

Nope, I'm starting over. Coil Rate is length and wire width.

Let's go down the wire width road. They all looked the same width to me.

Let's start fresh and NOT use number from Downey or others. Lets get out own data. It will be better.

 

What do you think about the method above to get the measurements? It could EASILY be done, and the ONLY difference would be the strut.

 

But 60#'s may be different on leafs versus rear coils. Will the leafs hold more than the coils, I bet they will.

Given time, I'll order the Sequoia coils and stick them on.

Compare the 1999 4Runner to the 2004 Sequoia for weight.

I really don't think the strut will make that much difference. I have used the Bilstein, Sway-A-Way and OME struts and really it was the coils that made the difference. Not the shock.

Bilstein makes a great shock, I just wish there rear 4Runner shock was 1" longer. Your not going to beat the huge shaft of the OME front strut.

Lets order up a set of Sequoia's. Robb are you game? I'll help you install them for free if we can test them out in the desert.

 

We'll run my 4Banger with V6 4Runner coils against your V6 with V8 Seq. coils and see if on the same obsticle you get the same results.

Any way you cut it they HAVE to be better than the 881's.

 

Do we know the coil rate on the sequoia coils? It may be higher than the Tundra, and therefore put it on the same level as the OME's... Steve, slow down here and look at what WORKS here and not what SEEMS to be BIGGER and therefore BETTER. Remember the whole SAW ordeal? You don't like the spring rate of the OME's, but you want STIFFER coils than the Tundra's or are you looking for the same rate as the Tundra's but in a longer coil?

 

The Sequoia coil looks very close to the OME 881...

 

Im game on the Sequoia springs.


If you got a spring compressor to loan, I can do the rest. (my Runner looks really funny right now with only the rear OME lift, still waiting on the Cornfeds to get here)

In fact we can compare the 99Runner V6 coils on my runner, and then turn around and compare the Sequoia too.... Value of "same vehicle" type of measurement.

 

(.)(.)

Oh yeah, we'll have 99 V6 coils to compare to Seq. V8 coils off the truck.

This will be prefect. I have 2 brand new compressors and an old one. We'll do it at my house, and use the air tools.

No problem, that will be "free" hours. Fab work is, fab work. Testing it testing.

 

Now THAT sounds like a valid way to determine the difference. Make sure to install the Sequoia coil on the same strut w/ the same top plate - NO CORNFED SPACER or REVTEK SPACER. Measure the before height and the after height ON THE TRUCK. If the gain in height is more than 12mm, then the spring rate is HIGHER and can be calculated using the difference in gross weights on the VIN stickers. That way, you'll know EXACTLY what rate you have

Keep us updated.

 

You know I will.

Robb, we're going to Martinez.
