    I asked Adrian at Icon about heavier springs for the 3.0’s and I was told they do not offer that. I was wanting to put a winch on but not if it is going to lower the front

    Hi everyone,

    This is my second post in this forum. I have been lurking the threads on this forum for years and have gained a lot of valuable Tundra knowledge from members on this board. Thank you to all those who post on here and provide people like me with your inputs on the Toyota Tundra.

    I have spent a ton of money on my suspension modifications and feel like my truck just keeps riding worse and worse the more I spend. I thought I did my homework and went with good components and went with good shops, but the end results do not show it.

    Current suspension setup on my 2019 Tundra Limited Crewmax with OffRoad package is 2.5 Kings OEM, no adjusters and not the extended travel option, and I have the Camburg tubular unibal UCA's. I also had the ICON RXT Option #1 installed recently. My coilovers are set at Kings recommendation of 3/4 inches of threads showing for about a 2.5 inch lift. My wheels are 20x9 Fuel with +20 offset, and my tires are 285/60R/20 E load rated L/T Nitto Ridge Grapplers.

    My newest suspension setup problem is that my drivers side rear sits a full inch lower than the passenger side. This is with an empty tank and nothing in the bed, not even a cap. My left and right front heights are not perfectly even, but they are within about a half inch of each other with the drivers side front being just a little lower than the passenger front. I did notice on the rear ICON springs that the top spring on each side has a different number painted on the topmost leaf springs. The number on the passenger side is 2797 and the number on the drivers side is 2196. Per the ICON installation instructions and per the ICON person I talked to on the phone, the ICON leafs are not left or right, they are the same. If anyone else has experience with this I would really appreciate your input!

    Another issue I have is that my on-road ride comfort sucks. The highways and roads here in the greater Los Angeles area are terrible. I feel every seam in the road and they seams are spaced out in such a way as my ride is very bouncy! I know some of this is probably due to my tire choice so I'm going to swap out the original tires and wheels for a comparison, but I have a feeling my truck will still ride "bouncy". I know Kings will revalve my shocks the first time for free, so I may take advantage of that and have them soften up the ride. Firs though I'm going to try out the stock tires and wheels and see how it compares. If stock tires and wheels result in an acceptable ride, I will then opt to go to a different wheel/tires combination...probably a 17 inch wheel and a 285/75/17 C load rated tires.

    Welcome! Glad ppl here could be of help and that you joined! CA roads definitely don’t help your cause. I see you already upgraded to aftermarket 20” wheels but have you considered going smaller? I know there are conflicting statements on whether the extra rubber does/does not improve on road comfort, but having the extra rubber certainly couldn’t make it worse. I am planning on dropping down to 18s from the stock 20s when I install my suspension. Just something to think about. You could also pull your shocks off and send them to accutune and ask them to re-valve them for a more plush ride. Or just have king revalve for free like you said but who knows how long that would take.

    edit: also, throw some weight in your bed. Grab a tube of sand and see if the extra weight helps with the ride. Are you experiencing bed bounce?

    I actually touched on both of those suggestions in my tldr read post. :) Sorry if it was too long.

    I'm pretty sure I'm not experiencing bed bounce. I think most of the bounce is coming from the front. I have an RSI SmartCap EVO Sport on order and I understand it weighs 230 lbs. ICON Option 1 should be about right for this setup but if not I can always swap out with the other leaf that came with the RXT and go to Option 2. I should not have to drive around with a couple hundred pounds of extra weight in my bed just to get my truck to ride the way it's supposed to ride, but I have thought of doing that for trouble shooting purposes.

    My bad. Missed the line about swapping back to stock wheels/tires.

    Don’t think I saw it, but what PSI are you running? When you swap back to 18s are em doen a little more than normal and see if that helps. Will help point you towards if it’s the suspension or the wheels/tires.

    I was running 40 psi in my Grapplers then dropped it to 30 and that did make a noticeable difference so I think going with a Toyo Open Country AT/III LT285/75R17 117/114Q C load rating will be a big improvement over what I'm running now as far as on road ride comfort.

    I’m still trying to troubleshoot why the left rear is unlevel. I measured this morning and it’s now 1.5 inches lower on the left (driver’s) side. I measured the exposed piston (if that’s what it’s called?) and it’s 7.25 inches on both sides. Does this rule out the shocks?

    I took a picture of where the bottom of the shock attaches and it doesn’t look right to me. Seems to me it should not be canted. Also seems to me there should not be so much room for it to move around. Can someone take a look at the pictures and tell me if it looks normal?

    I assume your truck is sitting level in the back?

    FWIW, my truck was
    Lower on driverside front (battery) and lower on passenger side rear. I could not wrap my head around it.
    But anyway, went to TRD fox pro’s and 17’s with Toyo AT3 C load. Huge difference in ride quality over the 20’s I had.

    Thanks. I didn't think it looked right either. I compared it with the photos on the installation guide INS-T015-2007+-Toyota-Tundra-2.5-Rear-Shocks.pdf (kingshocks.com) from King and it looks like there is supposed to be some "play" but the angle on mine looks off.

    I have the RXT configured the way it came, Option #1. I wonder if I configure the drivers side as Option #2 but leave the other side as Option #1 if that would solve it, or is that a bad idea?

    The front driver's side is almost 1/2 inch lower too.

    How is the road noise on the AT3's? I think the Grapplers are not too bad. You can hear it but it's low and not annoying.

    Waaay better than my Falkens. I really don’t hear them. My wife’s Kia is way louder than my Tundra so it’s like being in a noise cancelling car after that.

    Thanks! Based on what you’ve told me and what I’ve read in other threads, I’m going to switch to a 17 inch tire and go wine the AT3’s.

    I really think you’ll be happy and will give you a sigh of relief with money well spent. Sounds like you have a pretty nice setup going. My stock setup rode really nice and soft but was was really into swaying and leaning with a boat feel.

    Thanks man! I really hope changing to 17s and tires with more, and less stiff, sidewalls will solve the problem. Right now my truck is almost not even drivable because I can literally feel every imperfection and bump in the road. I think the only state that has worst roads than California is New Jersey, and within California, greater Los Angeles has the WORST roads in the state. How can a state with the 5th largest economy in the world and the highest tax burden and the highest gas taxes in the US have such bad roads? :|

    If my ride comfort doesn't drastically improve after switch to 17s and a less stiff tire, I'm going to give up on these Kings shocks.

    I think you’ll be happy.
    In my experience the bumps at speed are where the aftermarket shines. I don’t have experience with the Kings but I know people like them a lot. Although a pain in the ass, I’m sure you could sell them and not lose much. I was really enamored by
    Some of the stuff out there and their adjustability. That may be the ticket for you. Prior to finding the TRD Fox, I almost bought some Elka’s which were the same price and can be ordered tuned to how you want.

    Guys/gals running the RXT pack in option 3, does this look right?



    Icon states, add leaf between #2&#3 leafs counting down.

    Fits great between leafs #3&#4 but doesn't appear to arch the pack enough.
    :monocle:

    Edit this is what I'm going with, between#3/#4

    What you have as between #3 and #4 is actually between #2 and #3, which is correct.
    Less of arch as that add a leaf is much thicker.
