    It appears that not all Tundras have the "lean." Mine doesn't on stock setup, however does that mean it won't after I install my 6112's?

    I don't have any significant lean either, but I have read on some posts here that the lean is more pronounced after lifting, which I don't really understand what would cause that.

    I never had significantl lean either. But I would assume a full tank of gas and the battery being on that side of the truck could cause it. I’ve heard of it on other vehicles as well. You would think they would remedy that and take it into account when they build the vehicle. I’m pretty sure the pro shocks take that into account as I still don’t have lean after installing. And I’ve heard on this forum that they compensate. Weird

    @M C M has said that Toyota does use different spring rates. That's why the lean is less noticeable until you start changing things up.

    Do to everything being on the drivers side (battery, steering and etc). Doesn’t Toyota have a shim in there to account for it? That’s what I was told. On Coilovers install do they not put it back in?

    I am not aware of a factory shim. I agree with the fuel tank, especially the 38 gal, and the driver, battery etc. it is reasonable to expect lean on that side - I am just curious why some have it and some don't, and then when they lift it it gets worse. It almost makes sense then that Toyota OEM setup has some compensation for that.

    What would be better? Compensate with a shim, compensate with heavier spring rate, or if you have adjustable coil overs to tighten down the driver side to make up for it? If you add a shim I would think you would need to add a bump stop extension just on that side so you don’t collapse the shock.

    But I feel that when you start messing with spring rates and extending everything that your truck will perform awkwardly when hitting bumps or high speed off roading. Left front is going to be more firm causing the truck to bounce awkwardly.

    I'm .5" lower on the driver's side. Gas tank is full right now.

    Now that I think of it -- several years ago when I installed factory FJ springs on my 4Runner, there was definitely a left and a right (and marked as such). I believe it was for the same reason. The springs don't necessarily need to be different rates, but they were definitely different lengths. Of course we're talking about different vehicles here, but the concept is the same.

    Use me as a foundation to your theory. I have a 38g tank, outside of a tonneau cover and bedrug I'm completely stock.
    The truck doesn't sag or dip, or perform offroad in any uneven matter. I even have stock tires and rims.
    I'd theorize that would ever changes you made demand some scrutiny. I'm not saying any mods you did are bad... Just trying to localize the issue so your not running in circles . :popcorn:

    i came across this thread as i noticed the front of my sequoia sits slightly low on the driver's side front.

    i did some measurements, and driver front is 38.25" from ground to fender at the center of the wheel. the passenger front is at 39"!

    rear is nearly identical with 38.5" on driver and 38.75" on passenger (assuming that's the 1/2 tank of fuel)

    i checked both of my kings and they have exactly that same # of threads showing, so what the heck is causing the passenger front to sit that much higher?

    ideas?

    only things that's changed recently is the Icon UCA's, and alignment, but we didn't touch the lift, so can a bad alignment manifest this way?

    thanks for any advice!

    Seems like when you change coil overs the truck leans heavy on the drivers side from the extra weight compared to stock. I wonder how Toyota keeps it straight? Both stock springs are the same right?

    I want to say there is a right and a left. Maybe I’m wrong. My pro shocks have the truck sitting level in the front from side to side. Those have a right and a left spring. But if I remember there are 2 letters on both springs with an L and an R. It almost looks as if you clock the spring to get the proper preload. I’m just grasping now.

    I worked in manufacturing for years. Usually if something is marked “R” and “L” something is different.

    Easy. For the mere fact it cost money to mark it. Granted not much but times 250,000. Companies hate spending extra money for no reason. Like we told the new guys. If it’s marked different, then it’s different.

    It’s best to measure center hub to fender.
    Toyota’s are prone to lean. Tacoma 4runner tundra sequoia I have done lifts on and about 90% got the lean. Mainly the the lifts that went up pretty high.
    Negative camber can give it that illusion that it looks lower on one side. It will probably give you a bad measurement too.
    Your lean isn’t too bad from the measurements you provided . I’ve seen worse.

    add more preload on the side that is leaning. on my Tundra with Kings I have 14 threads driver side and 9 threads passenger side for example. I had almost 1" lean on the driver side. with stock suspension I had no lean.

    how many threads you have showing right now ? with 3/4" i would probably add enough to show 4 more threads driver side. suspension also settle after you play with it so even if it shows the driver a bit higher after you adjust it will come down a little bit. that was my experience after adjusting them twice because I'm OCD :)

    Your left/driver coilover has the circlip set one groove higher for lean compensation when new. Same spring on both sides.

    I’ve thought about this a lot. Maybe it helps while driving since roads are slanted down usually to the right? I think about it on this one road by my that’s a one way and it dips way to the left in the left lane. And I feel like I’m flexing a lot on the right I look out my passenger window at the sky almost. Just food for thought?

    Then they are marked to know which is one groove higher. See you were right.

    So after reading this above info on driver side lean is ok to use stock springs with new shocks and not worry about the problem since my truck is the same measurement on both sides? And if I go with a aftermarket spring then it's necessary to get a shim to balance things out?

    I have this issue. Ready to take it in to find out what can be done to fix lean and tire wear (after putting 4 new tires on yesterday).
