    Hi all, I have a 2014 CM 4x4. Looking to put Bilstein 5100 in all four corners to level the truck out. Should I put a diff drop kit in? Is it necessary? Pros v cons? Anyone NOT put the drop in with their 5100’s and experience any issues with any 4x4 parts or anything else?

    Thanks in advance...

    Anything under 2.5” really doesn’t need it. You’re changing the angle when you lift and the drop diff beings the diff back but than you are causing other drive line angles to change. Pick your poison.
    I have the bilstein 6112’s set at 1.9” and did not use the drop diff. I’ve had no issues at this time. I’ve lifted other Toyota’s up to 3” and did not use it.
    I would say not necessary for your application.

    I'm running 5100's on top setting, no diff drop. Haven't had any issues with 4x4. I did a lot of reading here including weather or not a diff was needed before I did the level. Everyone said it wasn't needed until 3" or higher.

    I’m at top setting with a shim on the driver side. I have a diff drop installed and everything feels okay. Had it on a for a bit now. Figured if I raised it a couple inches, it may be good to drop the diff back a couple inches but to each their own? :confused:

    Planning on going with the 6112/5160 combo eventually too so maybe that is an excuse to leave it haha

    So if someone has a 6112 with 3" they need a diff drop? Or can you get away with it if your mainly on the highway?

    I am about to be installing 5100's all around and do not plan on using the diff drop that came in the Boss4x4s 5100 kit, based on what I have read in the forum. I probably will be using the carrier brg drop kit since I will set my shackle at 1.5".

    6112 at the top is about 2.5” are you adding shims?
    You don’t have to but it’s getting close to causing the diff to have a greater angel which can cause premature wear. Might want to look at UCA if you’re lifting 3” to help get a good alignment. Might not be needed but worth looking into.

    Wait. If you drive it and feel a little vibration, then install the CB drop. Your drive line is designed to work with +/- 10" of travel. If you haven't swapped in longer shocks you're still w/in the operating range.;)

    Two shims on driver side. One shim on passenger side.

    Will hold off on installing it then. I just figured lifting the rear 1.5" it would probably need it.

    I will probably also be installing Firestone airbags in a few months too so that my Tundra doesn't squat so bad pulling my boat.

    CB drop isn't expensive or anything like that but, I don't believe in modifying the OEM unless necessary. You'll know if you need it. Best of luck.
