    It's a little stiff. But still better than stock.

    I know the 6112 uses a 600, pound, 14 inch spring, does anybody know the diameter of the spring ? Is it 60mm ?

    What else determines ride height then? Without removing weight from the truck, there are only two variables to play with, preload and spring rate. Spring rate was not the topic of this discussion, it was preload.

    You arent going to get anywhere here by simply stating that someone is wrong without any sort of counter argument.

    Hit up King. They probably have what you need and if not they can definitely make you any Spring you want

    There's a third variable: the length of the spring (obviously!)
    I think you have demonstrated your inability to comprehend how this works so I'm done arguing with you about it. Just please refrain from polluting all sorts of threads with this random misinformation; somebody might believe you... if you must, start your own thread about it and see how it goes

    I was thinking about that the other day. Also considering the Eibach 16x600 coils.

    The length of the spring was already addressed. You need the same amount of preload if the rate is the same. You have your head in the sand and fail to comprehend how springs work. You obviously cant read and dont understand the basic laws of physics. Maybe you should explore wikipedia: https://en.wikipedia.org/wiki/Spring_(device) https://en.wikipedia.org/wiki/Hooke's_law

    Or simply explore something other than these forums for information. You are nothing more than a lemming blindly following wrong infromation that people before you have stated.

    So why is it that Old Man Emu Coils 883, 884, 885, 887, and 888 (all of which have the same 590lb/in spring rate) have different lengths and provide different lift heights? The 883 coil for example is 375mm (14.76in) in length and the 887 is 400mm (15.74in) in length, and the 883 is stated to provide 1" of lift and the 887 is stated to provide 2.75" of lift with the same shock at the same setting? http://www.headstrongoffroad.com/uploads/1/1/8/4/11846658/lift_guide_shock_and_coil_selection.pdf

    Hooke's law is only for Force, Spring Constant, and Displaced length from free length (delta).
    If you applied the same force to the 883 and the 887 coil then yes you will have the same delta length but does not change the fact that the 887 is longer and will still cause the truck to sit higher.

    You are trying to use Hooke's Law to force the argument, and since you are not changing any of the variables (same Force, same K (spring constant), and same delta) the formula will equal no matter what if the spring is 10 inches or 1,000 inches.
    Doesn't change the fact that you just compressed the 10 inch spring to 9 and the 1,000 to 999, you will still have 990 inches remaining in length thus it would be 990 inches taller then the 10 inch.

    You are ignoring spring free length, going back to the 883 and 887 coil, if I theoretically compress that 883 and 887 spring somehow 374mm into an immovable table then you just compressed the 883 coil to 1mm above the table, the 887 would still sit 26mm above the table and thus provide 26mm more height (lift)

    You are running in circles here. The reason that the OME coils provide different lift heights is because the spring PRELOAD is changing. You are putting a longer spring into a fixed length. Longer spring in this fixed length means the preload has been increased.

    Im not forcing an argument. You just proved my point with your understanding of hookes law. The formula will equal no matter the spring length because the same force is exerted. Force = lift height. Higher force = higher lift height. The spring itself might be longer but the force exerted is the same.

    If you compressed an 883 and 887 spring 374mm since the spring rate is the same, the force exterted would be the same.

    However here is an example with a shock and 2 arbitrary springs which closely describes someone putting different springs on a 5100.:

    Distance between the spring seat and the upper mount: 4in
    Both springs have the same 600lb/in rate

    Spring 1 is 5in long
    Spring 2 is 6in long.

    In order to install each spring on this "5100", you would have to compress spring 1 1in, and spring 2 2in. This would be 1in and 2in of preload. This would be a net force of 600lbs and 1200lbs.

    If you moved the circlip up 1in (spring seat to upper mount distance: 3in) and then installed spring 1, you would now have 2in of preload. Which would be a net force of 1200lbs.
    With the circlip up 1in with spring #1, and spring #2 installed at the original setting we arrive at the same exact force of 1200 lbs. Which means the lift height will be exactly equal. It does not matter that spring 2 is 1in longer than spring 1, we obtained the same lift height by placing the same exact PRELOAD on each spring. Where preload is defined as free length - installed length.

    Your own @jberry813 quit that thread because he led a thirsty horse to a fire hose and the horse died from the amount of water sprayed in its face as it forgot to open its mouth.

    But it's not a fixed length!!! That's the point. Now you are even contradicting yourself. If you set the spring perch on a lower notch or back out the adjustment collar you are changing this length you speak of! Why do you feel the need to be such a dick?
    For what it's worth I have Icon coilovers on my truck. They came with 13" 650 springs which I cranked up a bit to get my desired right height. After rebuilding them I put on 14" 650 springs from King and had to back out the adjustment collar by pretty much exactly 1" to get the same hub to fender measurements I had before... go figure

    Just set my install date for June 12th :bananadance:. 6112's at the 4th notch with Eibach 650# springs and full Dakar leaf pack plus d29xl aal on Bilstein B110's in the rear. Will drive it like that for about a month until my front and rear bumpers, sliders and skids get installed.:bananadance::bananadance:

    I've read almost the entire thread, and didn't want to start another, but I can if it would help. Anyways, the question:

    6112's/5160's versus ToyTec Boss 2.0? Pros / Cons....discuss.

    They are approx. same cost (adding on aal, etc.) and lift height options
    I've talked to people that love the Boss 2.0, and I've also heard about durability issues or ride quality not being as good as expected.
    Comments about the Bilsteins are that it being harsher, rougher ride.

    I've read about 4 months worth of posts on the suspension lift options common on this forum and these 2 combo's seem reasonable for those that can't afford a $2K Fox or Icon, etc. and yet it be a step up from the 5100/885 option. I realize ride quality is subject but I'm looking for a "tight" feel, ability to absorb impacts without feeling harsh/cheap/spacer type feel.

    Final question; are 285's or 255/80's a non CabMountChop option with either one set at a max of 2.5" or do you really need to go to 3" to have the ability to run 33" tires and not CMC?
    Maybe the CMC isn't a big deal, just seems like an item I'd like to try and avoid.
    Thanks
