    Hi Everyone,

    Decided to level my 2017 Tundra with the Bilstein 5100s in the front on the 2nd highest setting.

    I called a local shop which specializes in offroad trucks to purchase my 5100s and install and they said they wouldn't touch my truck unless I bought their kit which included the front, rear, and new control arms. He also mentioned it wouldn't ride as well and because my truck does see trips to Baja once every two months... he almost insisted it.

    Newbie to these forums , but I see a ton of posts with owners just leveling it with the 5100s or 6112s and calling it a day. Do I really need to purchase the full kit/ is it important to install new control arms? Or was this a case of him selling something I don't need. Any help would be greatly appreciated!

    My suggestion is if you’re going to 3”+ of lift I would.

    Welcome! I believe the consensus is that if you're using the middle setting on the 5100s you don't need new control arms.

    Nope. Even on the highest setting I didn't. If your alignment is marginal maybe but not on the middle setting.

    The need for new control arms should be dictated by actual alignment results or intended usage, neither of which can be decided by any rule of thumb. The good news is by changing to 5100's you should already be lining up an alignment.

    Sounds like they're just trying to sucker you into buying something that you don't need. There's no need for new uca's with 5100's on the middle or top settings. Mine are on the middle setting and I had no problem getting it within factory alignment specs with the stock uca's. Not sure why they said your ride wouldn't be good either. I think most of us have experienced just as good, if not better ride quality.

    Mine is on the high setting of 5100's and yes, I suggest you do install UCAs made for 3 inch lift. Mine aligned "fine" but tends to wonder due to caster being on the lower end of "acceptable". Will be replacing my UCAs as soon as able and will be having to realign again at my expense.

    On middle setting not needed. What you need is a different shop.

    Some shops only install what they sell, they make more $$ that way, I would look for another shop not trying to scare you into an upgrade. 5100's you shouldnt need the uca's like others have said. You should be ok up to 3", however if your going to baja and driving fast for longer periods of time the shop is right, you will probably want to invest in better shocks, remote reservoir and such. Not knocking 5100, they have their place, just not in serious off road application.

    I changed to 5100 upper setting which for me was 2 5/16, I had it aligned and the caster camber were right on and the left toe
    was at 40 degrees spec is 10 -25 degrees.
    Do i want new control arms .. Yeah... do i need them probably not.
    heavy suspension compression off roading ... yes you need new UCA.

    And no differential drop. Tidewater off road said 2" to 2.50 not required
    and actually causes more CV ware.. they do all mod for checkered flag toyota here.
