    Ever jam your hand down the disposal to get the spoon that's fallen in? And even though you can see the on/off switch on the wall, and KNOW that it's off, you're still afraid the rest of your life you'll be wiping your arse with the other hand?

    Thats sort of like my experience today building the 6112s.

    I'm going to walk you through what I bought to get er done. And then what I did.

    Spring compressors.
    OEMTOOLS 25550 MacPherson Strut Spring Compressor
    $28, Amazon. They got good reviews, and for those who hate suspense, they were rock solid.

    IMG_7363.jpg

    However they don't fit over the coils.

    IMG_0550.jpg

    So, I trimmed them. I figured they weren't doing the heavy lifting, they were more to keep the puppies in place. Nobody ever praised my brains.

    IMG_4116.jpg IMG_9932.jpg
    IMG_8420.jpg IMG_4484.jpg IMG_4208.jpg

    Once I was happy with the fit. I was onto cranking them down. I spent a while trying to figure out how to mitigate the possible explosion that every how-to video describes. I decided to tighten the springs vertically. I liked the down pressure idea. Here's what I did.

    IMG_5689.jpg

    Vised a 6' clamp down and covered it with pipe insulation - looking back, the insulation wasn't necessary, but at this point I was trying to pad everything.

    IMG_1811.jpg
    What I wanted to achieve with this setup was a direction for blowout. ie if this thing went bad and exploded, it would explode up. (and then most likely brain me as it ricochets off the ceiling)

    Did a little wetting the whistle. Oh ya. Nice and slippery. Omnomnom

    IMG_8071.jpg
    Next I needed a 19mm socket. Some female to male converters and an impact gun.

    IMG_3353.jpg

    Alternating from right to left, I began the tightening. All the while envisioning somebody flipping the switch to the disposal.

    IMG_5376.jpg
    IMG_8584.jpg

    Put the shock parts together (without the coil) so I would know what measurement I needed to achieve before I could stop.

    IMG_7837.jpg

    I was setting my shocks to the second setting - the 1.3" - and that was just around 14"

    IMG_2038.jpg

    Most people do the third setting of 1.9" so that would be 13.5" compression.

    I'd measure back and forth between the two compressors. I've watched videos where they explain that if you go too far on one side the threaded bar would start to bend, but that didnt happen with me. They also said that you should do this by hand, but if you did, you'd end up looking like popeye when you got done. So I used impact driver. Half way around turns on each side in the beginning, then, when it started to get closer to the 14" spot, I'd just do a burst, alternating sides.

    Once at 14" I moved it over to the bench and slid the shock inside it.

    IMG_8418.jpg

    Followed the diagram that came with the shocks as far as how to put these together. Used a vise grip to move the setting to the 1.3" second spot. doohicky this and washer that. easy.

    Bought these:

    IMG_1339.jpg

    IMG_9728.jpg
    IMG_5600.jpg

    Lined up the "Out" label on the mount with the writing on the coils and the bottom.

    IMG_9666.jpg IMG_7653.jpg IMG_8400.jpg

    Then I power wrenched it until the rubber gasket started to balloon, then I switched to the torque wrench - 20lbs per foot til it clicked.

    IMG_5417.jpg IMG_6730.jpg IMG_3621.jpg

    Grabbed the inner shaft with vice clamp while tightening the nut, or else the whole thing just spins. So torqued with the right hand and held the vice grips with the left hand.

    IMG_8897.jpg

    released the tension on the coil

    IMG_0276.jpg

    done and done

    IMG_0339.jpg
    IMG_4713.jpg

    I didn't install them yet, I'm awaiting the coachbuilder .5" shim for driver side. Thanks to all 30 people for ordering from Coachbuilder, they are en route. Pop that sucker in and get er aligned.

    Bob's your uncle.

    Still have both hands.

    Don't be afraid.

    @MotoTundra I think everyone has an uncle Bob. I have one. And a brother Bob. Dont hear the name too much anymore.

    update to this thread. I did the drive side lean measurements and I was 3/16" lower on driver side, with over 30 gallons of gas, so I decided to put the 6112s in today and if my drive side sags later, I now know how to put it in later.

    And man am I mad.

    I've driven around the last 17 years in tundras with absolute shit suspension! These things are like taking off a pair of loafers and putting on Nikes. I installed the 5160s the other day, and the difference was minimal. These 6112s in the front make a huge difference!

    Went with the 1.3" second setting and when everything was put together, it was darker than a raccoon's asshole outside, so this picture will be updated tomorrow.
    From what I can see, she sits pretty level. Still going to put in the 1" Coachbuilder shackle but I'll have a better sense in the morning.

    If I go with bigger tires than these 275/70r18's I'll just take these guys apart and bump them up a setting or two.

    Tomorrow I'll get it aligned. I did have some rubbing when backing up, hard over to port. But I'm going to sus that out in the AM.

    i always do the on the truck method. i've used those spring compressors in the past, but so much easier to just take two bolts off the lower arm and let a jack do all the work for you!

    That’s sounds efficient. I’d never done it before, so I figured I’d go by the rules before I learned to break them. Really couldn’t have been easier putting the shocks together though. I guess it’s never a big deal until suddenly it is.

    Next time you do it, take pictures please!

    haha, i cant take any credit other than searching the intarwebz for that post! but its a good one and what i have followed on my trucks for years now. very easy. just make sure you have red locktite and a 250# or whatever tq wrench (can be rented for free at vatozone or orieleys) to reinstall the lower bolts to the spindle.

    What a great write up @JustForFun! I just purchased a 2019 Tundra and I too have the 6112 on order. When I remove the factory yellow Bilsteins, I want to keep them assembled for future use. I don't want to take them apart just to use the 'top hat.'. With that, how do you like the KYB top hat product? Would you mind sharing the KYB part number you used, if you like and approve it, I'll buy them today! You have a good photo of th box but I don't see a part number anywhere. Thanks in advance!

    Thanks,
    George

    Heya George,

    This brand top hat was what Amazon recommended as the most popular purchase for those who had purchased the 6112s. They seemed well made, but I guess only time will tell.

    KYB SM5737 mount kit.

    Good luck!

    Good work on the writeup. Those spring compressors look much better than the harbor freight ones i have used.

    James - I live in Southern California but travel to Framingham a few times a year for work. I noticed you are in Boston, that is a fun place to live.
