I'll offer a alternative point of view on AHC.
Look at the number of LC build threads that have a slippery slope of suspension mods. These suspension mods generally aren't cheap for the good stuff (which still doesn't come close to AHC in my mind). They are always a compromise between idealized trip use vs daily driving, load carrying capacity vs daily comfort, racing coilover for performance vs. longevity.
You can do a 1.25" AHC lift in 10 minutes with a 10mm wrench. Or more with a little bit more effort with some brackets. Or not at all, because it won't sag when burdened with gear or towing, and has 2"+ lift on demand when needed. With proven 200k+ mile durability. Try that in an aftermarket coilover which needs rebuilding every 30-50k miles.
AHC gives that all to you in proven package. You'll have the best ride you can get on the LC platform, with the widest breadth of competencies, and automatically dialed in dampening and performance since it's an active system.
No clearance or rust issues with KDSS for wider tires.
The LC camp is just not aware of what they're missing with AHC and they'll tell you that you need to rip out to "improve" the suspension. I wouldn't be able to understand why one would ever do such a thing as it's THE pinnacle suspension setup. I'm not overstating this, but removing for anything else is would be a huge downgrade. No brake dive, flat cornering, always right dampening for load and conditions. Lift on demand, with extra lift in low range, along with kneeling for ingress/egress/loading.
In terms of carrying capacity, AHC is pretty darn robust. I've towed a number of things, including my 28ft Airstream which has a tongue weight ~1k lbs. No squating or suspension too soft feeling. Which is an issue on the standard sprung and damped LC. If extra load is wanted, the suspension can be augmented to carry heavier loads. Airbags and coil spring spacers. In the future, there will likely be higher spring rate coils like the LX470 has now. And shocks can be dialed up, and the computer will match for conditions.
