    Love the Bilstein coilovers, def my #1 choice if I had to purchase some.

    If you added any amount of lift to your front end and did not replace your upper A-arms with aftermater ones, then your camber and caster profiles will be off as your suspension cycles . I'm sure the tech did 10/10 and aligned it perfectly at ride height, but if your tires move up or down (cycles, like hitting a bump or in a turn), it will gain or lose camber/caster differently vs when it was stock ride height. This might affect handle/ performance. The only way to rectify this is to change the genometry (new upper arms) or don't bother to lift it at all. This fact is missed by a lot of people who lift A arm trucks. It is particularly worse on tacoma A arms because toyota builds so much caster "gain" into the upper Arm (the pivot plane of the upper arm is at such a steep angle vs the pivot plane of the lower arm).

    ...basically you should get some aftermarket upper arms intended for "lifts" or spin down your coilovers spring until you are back at stock ride height. Who knows if you go back to stock ride height with these shocks you might actually like the stability better, because you have a bit more down travel.

    So dumb question but has anyone adjusted the height of the coilovers once installed?

    I've had adjustable coilovers in other vehicles but typically they have 3rings. I'm not sure if it's just Lefty on the top ring to lower and righty on the bottom to raise without any issues.

    There's not much information on the web on these lol

    I did... sorta...

    There is a lot of tension on those springs. I would recommend adjusting them before the install using a high quality professional spring compressor.

    Having said that, I went down to Lowe’s, bought some 300 lb zip ties, put a jack underneath the LCA and compressed the spring under the weight of the vehicle. I removed the tire and then I used 6 zip ties per spring. Then, I lowered the the LCA to full drop by blocking the frame. The spring wasn’t even close to being loose, but it did take some tension off allowing me to turn the race nut with the spacer wrench. I lubed the race, threads and contact points of the spring with oil. I also removed the bump stop and used a cheater bar. I was able to get four complete rotations until the tension on the spring made it very difficult to turn.

    At that point I called it good! I locked everything down, re-compressed the spring, cut the zip ties, and re-installed the tire. I think I gained 1/2” or so with four rotations, but that’s off memory.

    Ah poop, I guess I might rent a spring compressor then. Thanks for your insight!

    I followed the install height instructions but since I have a dual battery set up I don't see the need of my driver side being an extra half inch higher for taco lean when the weight is already even-ish. I might just drop it an extra quarter inch and call it good.

    In my experience, a rented spring compressor or home unit isn’t going to do it. The problem is the coils are too big and the spring is too tightly compressed for a DIY spring compressor.

    You need a unit like this:

    Using the process I described, you should be able to adjust or compensate for your unintended lean no problem

    Just decided on 8112's,8100 now the spring choice,, I have sliders but am not planning on doing the after market bumper and winch. I'll let the other guys pull me out with a strap kit I just purchased. And will tip you of course.

    I have the heavier springs, (650Lb) and with a Warn semi-hidden front bumper, without the winch they felt a little stiff.

    So the springs that come with the fronts will be fine.

    Deaver, Alcan, or Icon Rxt's are what people are generally running for leafs. But if you're not carrying anything in the back and not looking for any lift, the 8100's feel great with the stock leafs.

    I’m clueless.
    Why did you go with Icon RXT instead of Deaver. My only time dealing with deaver was an excellent one.

    Thanks for that, I am looking for an inch lift. Does that make a difference?
    I’m thinking a book like suspension for dummies is in order for me.

    You’re no dummy. You’re asking all the right questions and doing your homework. We’re all modifying a highly engineered vehicle and there are a lot of aspects to this. The fun part is getting educated along the way and knowing what you did, how you did it and why you did it.

    Was easier for me to get Icon's up here in Canada than Deavers.
    Icon RXT also comes with a spare leaf so if I ever add a cap or other heavy stuff I don;t have to order another leaf.

    The 8112's are adjustable from .5 to 2" lift. Come set from the factory at 1.5" for the DCSB trucks with the 600Lb springs.

    So you can adjust them to whatever you like :)

    Here is the install instructions for them.

    Do these work with the improved SPC UCA? Thought I saw somewhere where that hose connector interfered or hit with the spc uca.

    How's everyone liking these? Has anyone had to rebuild yet, if so at what mileage? Getting ready to go with these or kings. So much more info out there on the Kings.

    Loving mine! Was off-road with them today (nothing serious) and just love the way they perform --especially when moving over 20mph...

    No need for a rebuild yet, but only have about 10,000 miles on them...

    SOS Front bumper with winch, Dual battery, RCI bed rack, Smitty built XL, 8112's in front, King 2.5 adj in back, Armor on the way.
    Well pulled the trigger on the 8112's. opted not to get the rears as I have new King 2.5's with adj waiting to be installed. Price dropped back to 2018 numbers. got mine for 1500. Ordered the 700lb springs and didn't even think about it. Build is getting up there and I'm far from done..SSO bumper, winch, dual batteries, Skid, Roof rack with crap. ..bed rack and RTT going on shortly. Did beef up the rear to OME HD leafs. I carry allot of weight most of the time.

    If you've said before, I apologize, but how much front lift are you guys getting? Seems like 2" is the max that Bilstein is saying. Is this more of a precaution because of the cv angles, or do they really not want the assembly to exceed the 19 11/32" that the install document was showing.
