    Hey SC if you want to come by anthem in henderson and go for a ride you are more than welcome (you make the decision :D).. It just seems pointless to try and argue over what some think is right vs wrong.. again I have years of building trucks-cant speak for anyone else.. some just choose to hate-lol

    not trying to be a hater here, just trying to understand the reasoning behind adding a spacer to a coilover setup. i have never built any truck up from the ground, so you have some more experience than i do.

    so here goes: adding the spacer to the icons was done to lift the truck 3" and maintain a good ride versus cranking the coils, right? but since lift on these trucks is only achieved by either cranking the coils or adding a spacer, you decided to add a spacer. but wont this cause the shock (and therefore the coils) to compress a little more than it would at ride height, thus doing the same thing as if you cranked the coils?

    again, just trying to gain some knowledge here, as adding a spacer to coilovers seems counter-intuitive to me...please school me, im always open to learn!

    A top plate spacer (which is what he installed) achives lift by lengthening the shock/spring assembly. Being as he is running TC UCA's, no damage should come of this set up.

    nope-having a spacer on top of a coilover if it isnt to large is like sort of having a dual rate coilover.. It will only put so much preload on a specific spring.. If you had a single rate coilover vs a dual rate coilover the ride depending on how you set it up (weight, hp, driving habits etc) would depict what rates you would use.. But it would be a better ride than a single rate.. Its not as simple math as you may think to be honest, much more technical.. But trust me I have done it both ways many of times just experimenting on my rides as well as customers rides to try and make sense of it.. There is always more experimenting to do and thats half the fun to be honest.. I enjoy doing this stuff and trying to figure stuff out and achieve something better if at all possible.. Dude I don't think your a prick at all- I am way layed back and like I said- simply enjoy doing this stuff.. I even built a crazy lift kit for my golf car w/ dual rate fox coilovers etc. I like to experiment-mad scientist style

    understand that, but how much more do those TCs give you in downtravel? do the steering arms limit travel at all?

    What do you mean "Nope", and all this dual rate stuff??? "Dual Rate" is if you had a DUAL rate spring/shock. You added a 1" spacer to the top of the assebled pack, thus making it longer. The spacer adds no "Rate" to the suspension, it simply adds 1" length to it. The spring rate stays the same, the dampening rates stay the same....

    well sure the steering will limit travel as they are not extended, but at the same point I am not running a LT setup, therefore will not treat it like one.. And the UCA also can only go so much, but again not a LT setup.. I will most likely to be honest put limit straps on my current setup just to be safe and not over extend my components..
    Like in my original post or shortly there after I mentioned I will be upgrading to the engage lt setup soon, which will be much more going on..

    if you add a spacer to an assembled pack it still will stiffen it very slightly as its still pushing the entire c/o between upper and lower ca.. not much but still a little.. again hence why i chose to do this setup vs cranking it 3.5" to begin with.. and stating the dual rate thing is just to get an idea not saying thats what im running.. guess i shouldnt confuse everyone here..
    No worries- it works fine, rides great, tracks straight and no complaints.. If anyone is hesitant of doing this- then my suggestion is DONT do it.. Do what your comfortable doing and you should be fine.. I am here to just show everyone what I did and explain how it worked for me.. Not trying to start some crazy bashing thread here.. Seems like stuff can get blown out of proportion pretty quickly

    but i guess this is my original point. i dont believe you have any downtravel to limit. your at ~3.5" now, so your pretty much maxing out an OEM truck concerning downtravel w/ the spacer and coilovers. that is not taking into account the ext downtravel the UCAs will give you (which i forgot about in my original posts until chriss brought it up). so how much more do UCAs really add to your setup?

    i guess this is why i questioned the original idea of installing a spacer on top of a coilover setup...no more downtravel (even if it is not a LT truck. downtravel still makes a truck ride nice!)

    again, just trying to educate myself and learn.

    Hmmm....Calling it a Dual rate is misleading. Nothing dual rate about it. And feel free to get "Technical" about suspensions and trucks. I have had my hands in them a couple of times myself.

    FWIW, the TC arms give it almost a full inch more down travle.

    hey chris-no doubts that your are tech savvy-was meaning for the others.. do you feel there is better ride from a single or dual rate c/o.. I know there are lots of variables but generally speaking, what do you think

    Depends on what terrain is going to be driven. Obviously, Dual rate is a better set up for most off road applications, as you get bump absorbtion, flex, and the ability to fight bottoming. I have been working on a dual rate for our trucks. A 500/650 set up. BUT, given the short length of the shock/spring assembly, Im not finding it easy, nor am I convinced any benafit on a DD. Being as I dont have the machines to wind my own springs, the only way a dual rate Co can be made is by useing 2 springs, and a divider. FWIW, all springs on CO's are a single rate, non progressive. And I know of only 2 mass manufactures of springs for CO's, and they are Eibach, and OME.

    I agree dual rate- as I realize a single rate is for obvious reasons not a dual rate I was just in a weird way trying to explain that using a spacer w/ a single rate would give it a better ride.. strange way to describe yes, but that was my overall intention.. Anyhow what kind of trucks do you build? Im not going to state I know everything there is to know about suspensions, trucks etc. I have built alot of them over the years and have fun messing around.. I have also done some stuff for sportsmobile vans and work on them regularly as well as sand jeeps.. I am always open to new ideas and suggestions- I can never know enough

    Another little tid bit for people to chew on...The TRD springs are "Progressive", which is NOT to be confused with a dual rate spring. A progressive rate spring has a rate, that build up as the spring is colapsed in a progressive maner. Example, the first inch may be 400#, the second inch is 500# third inch 600#, etc.
    A "Straigt rate" or "Constant rate" spring would be: 500# first inch, 500# more the second inch, etc....

    A "Dual Rate" spring is basically like 2 constant rate spings joined at the middle, where as the first sprng will have a low spring rate, and the second will be a bit higher. They also look VERY different from one another.
    Constant Rate:

    back a while ago I used to use alot of h&r springs on our big lifted trucks.. I havent used them in quite a while-but were not all that bad..

    I have built quite a few different kinds, from street legal 10.5 sec. 1/4 mile'ers, to SCCA race trucks/ 2 cars, to off roaders. Big and small. For the last 15+ years, I have had a fondness for Toyotas. I dont NEARLY know everything, but I know more than most. ;)
