    Same spring rate per inch.

    Ok i get that 600lb vs 600lb. But doesn’t less preload make for a better ride?? And wouldn’t a longer spring technically give you less preload at the same height?? Sorry for my redundancies but I’m new to this and I’d like to learn..

    Thanks

    There are plenty of threads in TW that cover this topic and I would best advise you taking some time to read up on them to better understand the subject. I am by no means an expert on the matter but I am learning.

    I also have a terrible tendency to use the incorrect terminology when discussing "preload." You do not have "more or less preload" when you change the spring length, you only change the location of the preload ring. Technically speaking, you have the same amount of preload with a 13" spring as a 14" spring to achieve the same amount of ride height, assuming the spring rates are the same.

    Read some of the Accutune Tech articles and maybe that will help explain better.
    http://accutuneoffroad.com/articles/spring-preload-matters/

    Most springs are linear, so if you were to "rate" a spring, you would find that for every inch, the load multiplies. 13" 600in/lbs spring at 1" is 600lbs and is 1200lbs at 2". Same is true for a 14" spring, therefore the preload to achieve the desired height never changes.

    We get confused because so many people, myself included for awhile, believe that preload is directly related to the ring position on the body and not the compressed length of the spring.

    Thanks after reading this, & the preceding posts on this thread.. it sounds like i need 650lb coils (not 14”) to achieve 2.5” without too much preload.. but to be accurate, I’ll call Ryan at accutune tomorrow... again.. he’s been good with me so far.. i just don’t want to bind these 600lb coils trying to get the height i want..

    This whole preload thing is really hard to think about, especially on Tacoma's because of their space constraints. @desertjunkie760 got it right.

    Ride Height = (spring compression due to vehicle weight) + preload

    Any spring that is the same spring rate will compress the same amount and give you the same ride height at the same preload.
    Higher rate springs give you less preload, but a stiffer ride.
    Softer springs give you a smoother ride.

    Tacoma's are over sprung (front and rear). So we want the softest springs possible on the coilovers.
    We've had good success with the standard 13" long, 600 lb/in spring on 2nd and 3rd gen Tacoma's with light upgrades (sliders & skids) and reasonable lift heights.
    For lighter upgrades or taller lift heights (2.5" +) we recommend a 14" long, 600 lb/in spring.
    For people with steel bumper, sliders, steel skids, & winch we recommend a 650 (usually)
    And for fully loaded Tacomas with all that plus RTT, bed rack, heavy gear load, & heavy passenger load then we start getting into 700 lb/in springs.

    Question, why do you say 14”x600 spring for 2.5”+ lift over a 13” at the same spring rate? What does that do for the user if the spring rates are the same?

    The 14" long springs can take more preload without going coil bind.

    The longer spring has more travel so you can add more preload before they go solid.

    I told Mike at accutune I was getting a steel bumper/winch and have sliders and he still suggests sticking with the 600lb for a 2" total lift.

    Adding an ARB twin compressor under the hood too now. I think that puts me at 180 pounds extra at the front not including steel sliders.

    Actually, yes, just took this about a month ago. The front is 650 lb/in King coils set to ride at about 23" from hub center to fender lip.

    The rear is standard CS047R leafs but I've since rebuilt the rear packs to put in an extra leaf to bring the back end up a bit. I don't have an updated photo yet, though.

    Are your fronts the extended travel? Did you get 3” of lift out of them?

    I have extended travel, standard IFP no-reservoir shocks and I have Camburg ball joint UCAs. I have the driver side collar set about 1.5" down the body and the springs sit compressed to about 11.5" from their full 14" length. I could probably turn the collar down farther on the body if I wanted to push the front end up higher but I wasn't after 3" of lift.

    Makes sense, thanks man. I’m trying for 2.5-3” all around. I want the truck level. I’ve got 2.5’s with resevoirs for the front with 650lb coils and I got 2.0’s with resevoirs for the rear with a 1” AAL. I’m running the same bumper and winch combo upfront. I’m also trying to avoid any nose dive when braking

    @austin2009, as it sat in that photo it was pretty much level with a roughly 300 lbs camper on it. It squatted a bit full loaded, which is why I ended up putting the D29XL in the pack. With nothing in the bed and the camper on it sits at about 24" hub center to fender and it squats about 1/2" to 3/4" or so with my normal camping junk.

    I run IFP 2.0 rears, also no reservoirs. I wish I had rebound adjusters I guess, but ultimately not sure if I would have done reservoirs or 2.5" no-rez shocks if I had it to do over.

    I'm very happy with the ride over all, loaded and unloaded. I might need to tweak the rebound damping (it's kind of harsh coming off sharp steps) in front but otherwise definitely satisfied.

    How much weight would you say you have in the front? I'm planning on around 180lbs + sliders.
