    hello all just general question. Has anyone that's done a level under 3" also done a differential drop with 5100s mid to top setting or blocks. I installed a 2" supreme suspension block kit and was just wondering. It's seems everything I have researched says it not needed but was looking for some real world feedback.
    Thx

    You could get away without installing diff drop for a 2 inch leveling, but a lot of guys install them. Cheap insurance.

    Coach builder +2 = 1.25" shackles came with diff drop so I installed them. Might not be needed for daily driver but doesn't hurt to have

    Yeah I wasn't sure but I find a couple things that said dropping when not needed or to far could do more harm than good and all the drops I have found are basically matched up with 3" kits.

    Technically, ANY lift changes your cv angles. General rule of thumb, I think is 3" or over, you need it. That said, for 5100's on the top setting I'd still do it.

    The diff drop is cheap and easy to install. Go ahead and do it with any 2"+ lift is my recommendation.

    I'm looking into the Supreme Suspension 3"/1" lift kit. Was trying to get some feedback on anyone that was familiar with them. I've seen good reviews but also wanted more feedback. I'm kinda back and forth between it and the one from Low Range Off-Road.

    Curious, does the TRD Pro have any sort of diff drop? I know that is 2 inches higher in the front than the standard ones.

    So a lot of guys talk about coach builder and I see it's a vendor here but when you go to vendors it just gives a email and I can't find a website for it or the actual company name ekstrom designs I can't find a website.

    As we talked before if your going back and forth let me now help you out as far as the supreme suspension is concerned. Get the lrt! The only reason I went with the ss is they offered a 2" kit and lro did not. I didn't want any higher and I am eventually putting the trd pro setup on so I wanted to see how I liked it that size. The ss kit is not bad by no means build quality is good all machine aluminum and power coated, that would Be where the comparison stops. The ss kit uses bolts to install the block spacers back to the housing this turned out to be a major p.i.t.a trying to get them lined up without cross treading while the strut has pressure on it sucked. I watched several videos on doing the blocks and I can't for the life of me figure out how they get the lca down enough to just slide the assembly in place. I am not a certified auto mechanic but I do work on machine equipment for a living and have worked on vehicles most of my life and I couldn't figure out how. However by the second side it went easier. That said lros kit uses pressed in studs that would have been nice for lining up during install. Second lros kit uses close to or better replacement factory bolts and nuts ss's kit does not switching back and forth from metric to imperial was a bit of a pain. Also I didn't install the 1" rear block from the kit (didn't feel I needed it) but lros is beveled 1 degree for better driveline angel a major plus. Also lros diff drop is way better than ss's. lro's seems more though out whereas ss's seems like a afterthought thrown in. Hope this helps, but if I can help you with the indecision just make one the more you go back and forth the more opinions you will get and that will just make you more confused. Just stay away from the poly kits and you will be fine. Just my 2 cents.

    Hey Mike............I have the 5100 at top setting and I installed the diff drop kit. Like some of the other members reported, it's cheap and fairly easy. Anytime you are lifting a vehicle ( drooping the suspension ) you are putting more wear and tear on the CV joints and the other suspension components. Is it absolutely mandatory on a 2-1/2" lift ? Probably Not. But it will benefit the longevity of your suspension components. Good luck no matter which route you take........

    Yeah I have decided to put it on after looking into it, when I bought the kit originally it was in the pics but they didn't send one with the kit didn't know if I needed to raise a stink about it if I didn't in fact need it bu I contacted them and the customer service was very nice said it was their bad it was in the pics and sent me one free of charge. So I'm just waiting for it to arrive and I will put it on

    Think that is a wise move. Post pics of the truck when you get it lifted.

    I think I'm going to do a build tread but just haven't had time. On a side note do you have the 5100s in the rear? I picked up a set because I was going to do 2"-1 lift but after putting in the front 2 I still have 3/4 rake so I might just leave it. Did you notice any improvement over the factories. I do have the trd off road package with the trd sway bar.

    I have an SR5 and have the billy 5100 top setting up front, and just the stock shock and no lift in the rear. I do offroad in the desert and have no issues with the stock rears. I don't do any high speed offroad, so don't think I am going to heat the shocks up and get shock fade. I do get some good articulation from the rear, I just drive it pretty mellow so I can tow my 24' travel trailer home.

    I truly appreciate the advice. A lot of good points brought up. Just when I was leaning one way I think I've permanently swayed back to the LRO kit. I did like the strut spacers being black from SS, but quality is much more of an issue. Thanks again.

    Hey Blue,

    Did you ever get an answer to the question and did you add a differential drop kit!

    For a $30.00 investment , I think it is a really smart move Steve. One of the bolts is a pain to get to to tighten, but with a buddy helping out, it really adds to the convenience. Good luck with all.

    Quick question guys . . . . I didn't do the diff drop with my Bilstein 5100 (top setting) install. I feel like I have a slight 'howl' noise coming from the front anywhere from 20mph to 45mph . . . It's very slight, but it's definitely there and I am thinking CV or axle noise caused by the new angles? Any thoughts would be appreciated. THANKS!

    That’s not a bad angle at all. How is your tire wear?

    Probably too early to tell, but looks fine. So you don't think that is the source of my howl on decel? It's an '18 with about 8K on it . . . just started after the leveling, so I have to think it is an angle somehwere . . .

    That wasn’t a diff drop. It was a carrier bearing drip. Same idea. Different drop kit. That coachbuilder keeps your drive shaft from shaking your car apart after changing those rear angles
