Yep. You definitely need to apply that UV protectant afterward.
What have you done to your 200 Series this week?

yeah I'm hoping that with the UV protectant it lasts a year or two
I usually just repolish mine on vehicles that sit outside every 9-12 months. A once over with a polisher gets it done. Followed up by some paint sealant then 24 hours later UV protectant.
That’s pretty much how it was for me pre AHC lift, but since then it’s almost distracting (though slightly improved by the fluid change). The front dipping almost feels like I’ve randomly tapped the brakes, which is especially a weird feeling when I’m in the middle of accelerating.I think this is one of those things that is more a mental block than anything. Yes, I can feel it lowering if I'm being attentive to it. That's just AHC telling me I'm hunkering down into freeway mode and that's cool. Enhancing aero to save gas, increasing stability, reducing CV wear, and locking in on a good road trip.
So very few suspensions out in the world are active and do all the magic that AHC does.
Im considering just reversing the lift and just using AHC high when I need it.
I wonder if the change in geometry of the arm attached to the height sensor is responsible for what you are feeling. I’m just kind of brainstorming on that. Or maybe the vehicle drops more quickly (or unevenly) for some reason because of the additional height.
I wish I knew more about the AHC system, but I’ve only had experience with bleeding it and a few globe and a pump replacements.
I did the same thing. Replaced my globes, removed my wheel spacers, and put the sensor lift back to stock (using TechStream as a guide) and it's soooo much better. Sure, I like the 'higher' look, but I'm not going to try that again without all of the added components that will 'hopefully' keep it as close to stock pressure as possible.
You hit the nail on the head in regards to pressure. Without augmenting the physical coil springs, AHC sensor lift will put more of the vehicle weight on the hydraulic portion of the system; less on the coil springs.
The higher pressure when released to decrease ride height will drop more quickly and dramatically. Falling onto coil springs that aren't supporting as much with less pre-load.
Proper way would be to augment the coil springs with spacers to retain more stock like pressures.
Fronts using either OEM Toyota 10mm spacer or E&E Off-road 13mm spacers.
Rear could use 20-30mm coil spring spacers.
Im wondering if aftermarket coil suspension on the LC could benefit from front spacers and improve ride quality?
Also, anyone has any specific recommendations with regards to 20 and 30mm rear spacers?
I was going to get SuperPro 20mm.
Are you aware of any good write ups on reversing it? My attempts to search for that mostly turn up posts about deleting AHC altogether.
Reversing a sensor lift? Here's what I did after replacing my globes: I first adjusted the height sensors so that the front and rear were at stock height (front - 19.5"~19.75" / rear - 20.5"~20.75") - measured from center of wheel hub to top of wheel arch - and then I hooked up techstream which showed the offset of the previous setting, and I again adjusted each bracket on the height sensor, dynamically while the vehicle was running, to get it as close to the previous setting as possible. I wish I would have taken pictures of each sensor's arm setting as it would have saved me a lot of time. Also, I feel like the adjustment for those height sensors could have been a much better design, like an adjustment screw for better precision, rather than that sliding arm, which is horrible (IMHO).
Thank you, time to get into tech stream I guess. Fortunately I think I may have pictures of my sensors.
Mine were dead center of the adjustment range before I messed with them

I also just bought one of these! Looking forward to the install
Cheap plastic auto panel pry made quick work of popping speaker cover free. I chose to install all the fasteners though plenty solid leaving a few out as some have done to avoid the clips ( they align if you pull the mount all the way forward on the cover)
I pushed it back a hair to allow the ctr fasteners on sides to land within the square standoff boss of the cover clip. Curve of mount still sits flush on cover.
Used #10 3/4” screws from your local store fastener aisle and pre drilled with 1/8” bit.
Got my 6112/5160 kit and new uppers installed last week. Did 500 miles and took it in for a nut and bolt check (tightened up a loose rear upper shock mount that was clanking over bumps.) also had them install my DRKDSS BOTCK bracket while it was on the rack. Have an alignment tomorrow morning and then I’m set for the season.

Our LC and Tundra share the same style boring toyota keyfob. I had a sticker on the LC fobs to tell them apart but got tired of that so I grabbed the MGM color match and painted the LC fob. The paint is holding up well thus far and the MGM is just different enough from the black to easily tell them apart. I may have also been a little bored.
