This is correct!

 

Great, thanx for the info

 

I should have pricing on the 23rd.

 

I tried to compress the springs on my '09 to help get the struts back in with the 2" AS leveling kit... Long story short, I removed my LCA bolts to get them back in. Even with my Thundergun set to max (625 ft-lbs), all the spring compressors did was bend the massive bolt inside them trying to compress the VERY stiff springs on my truck.

It seems best to take the struts to a shop that has a hydraulic spring press to take the struts apart and reassemble them. I really don't think it is safe with a standard spring tool. If it fails, there is an awful lot of energy stored up that will release quickly.

 

Assembly yourself kit comes with Adjustable Threaded collars with wrenches, Eibach springs, 5100 Bilstein shocks, instructions. $599.99 + shipping.

 

What is the spring rate you guys decided on?

 

700lb

 

Isn't that a bit stiff?

I estimate the stock rate at 525-550 lbs / inch
The Icon Coil-overs are 605 lbs / in
The Fox Coil-overs are 650 lbs / in. (and only $700)

That's ~27% stiffer than stock.

 

We don't think so. The truck rides very nice, only slightly firmer than stock. You would love it, I do! I edited this because I don't want to convey anything negative, that is not my intention at all.

 

But none so far on Fords (except yours), not to be rude but any reasoning to the stiffer spring rate that you chose?

 

Ok. So instead of explaining why you went with a spring that's a minimum of 27% stiffer than stock, you just get defensive?

Use your experience and tell me why I would want such a stiff spring? What is the benefit? 'Cause I've been down that route before, and I don't see any benefit to going stiffer, especially that much stiffer.

Are my measurements of the stock spring rate wrong? If so, why? I don't have detailed equipment to measure with. Just weights and a tape measure. My calculated rate comes out to be close to what Icon says the stock rate is. So I'm pretty confident it's within 50 lbs / in.

Not to mention that the Bilstein comes valved for a spring with the stock spring rate. It's NOT valved for a spring that much stiffer than stock. Shocks are gonna feel weak and underdamped with that much force on them.

I honestly expected you to day 550, or 575 lbs / in. 700 just seems much too high.

As far as your experience. I dare say that the Fox guys have alot more experience with springs and shocks on trucks in general. F150's in specific. So to talk about your experience than then dismiss the Fox products is very hippocritical.

And I brought up the price because your setup does seem extremely close in price to the Fox's. And your's was an assemble it myself deal?

You listed $600 + shipping, assemble it myself.
Here are Fox 2.0 Coilovers for $680 ($340 each), already assembled.

Granted your product is cheaper. But mot much. And honestly if the Bilsteins were even in the running for me anymore, that'd be too close in price to the Foxes for me to consider them.

And with the recent failures of Bilsteins when used off-road, especially when used at a higher setting, I am not considering using Bilsteins at all anymore.

Sorry to bust your chops. I'm sure you'll find some buyers, as $80 is still not chump change.

 

So guys... I am not getting defensive, Let me try to explain. Number one I own a $48k F150... Do you really think I want it to ride like a brick, or piece of ***** We tested the stock spring rate. Then we tested quite a few different Eibach springs. When you compress a spring with our adjustable threaded collar in order to get the lift we were looking for the spring rate changes. After all our extensive testing the 700lb Eibach gave the closest to stock ride while still having 2.5" of lift.

 

Except you cannot physically increase the spring rate of a spring by compressing it. Physics just doesn't work that way. You increase the preload, and therefore the resistance to initial movement. Once you start the spring moving, the rate is still exactly the same.

For example, if the 500 lbs / in spring is compressed 3 inches by preload. Any load below 1500 lbs will do nothing. Anything above and the spring will move like normal.

If you have to crank up the preload, why not just start with a longer spring in the first place? If you're using a 14" 700 lbs/in spring, why not instead use a 16" 600 lbs/in spring?





By the way, it wouldn't happen to be Toytec that you're working with, would it?

Looks awfully familiar.

Just looking up a reference point.

 

Your crappy attitude isn't going to help you sell anything here.... and i also don't think your friend would appreciate you poorly representing his company while he is trying to branch into a new market.


edit: is it we or him. First post you said it was his company and he used your truck as a test vehicle, now it's "yalls" company.

 

Guys can we please stop this, and back up. I have no attitude. If you feel that way, please accept my apology, not my intention at all. I am not on here to fight with any of you.
Yes Toytec is working with us
Thanks.
