Sensor Lift adjustment/install guide?

[NolaNomad]

I'm up on here trying to figure out how not to screw up a sensor lift on my '06LX470. I think there was a thread showing how to do this correctly?
I saw a few but wasn't an install guide ?
My goal is to gain a lift no more than 2 inches to get lager tires under and correct for a heavier than stock rig.

I've got the King Springs, a pair of LC torsion bars, pair of LCA reinforcement brackets so far.
Thinking to first swap the LX torsion bars with the LC's and get those indexed. Re-locate the rear AHC sensors (move them up) then raise the front AHC sensors by screwing the threads higher.
Then Swap into the King springs, get an alignment and tweak the torsion bars. I see that I'll need to get Techstream running, still having trouble with this
I do have a cargo drawer system in back, a spare tire carrier on the hitch( 275/60r18 KO2's) and a steel bumper upfront.
I don't know if i need spring spacers ontop of the King springs (the big hockey pucks) or if I need the Japan 4x4 shock spacers that go between the arm and the "shock"...?
Anyone know of a more detailed install guide or is my plan no quite correct?

It's counterintuitive but a lift on an IFS vehicle does not allow it to fit larger tires. The tires operate in the exact same range of motion, the only thing that changes is the stationary point, the ride height.

Measure fender to hub on all 4 corners first. I like to use the tape measure as a plumb bob so I my measurements are consistent.
Then swap in the King springs and set your rear AHC ride height. Since you have some weight out back coil spacers won't hurt. Do an additional 10-15mm of spacer on the left to level it out.
Adjust your front AHC sensors to the height you want then measure for the correct amount of droop. If that's good now check your AHC pressures. Don't bother with the LC torsion bars yet. Just crank on the AHC torsion bars first as is shown in the ABC's of AHC thread. The drivers side adjustment may bottom out before you get your numbers where you need them but it's easy to reindex the bars (and install the brackets) to get more adjustment. Once your pressures are where you want them you're done. Other than an alignment.

I'm a little confused about how to re index the new LC bars- i do see some factory white pen marks on the front spline and socket but do I just find the flat spot and count the splines and m ark that? What if I've already added a few full turns to the existing LX bars?

I would not swap in the LC bars until you see a definitive need for them. Reindexing the AHC bars will more than likely correct your pressures.

I too, doubt you'll need LC T-bars. Until fully build. i.e. bumpers, winch, swing, full undercarriage armor, sliders, fridge, draws and loaded.

If not enough weight, you'll not go into LOW and loose some dampening (comfort mode). Comfort mode, is not only for passenger comfort. It reduces shock of impact from bumps in the road (Rocks, ruts, bumps) to shocks & globes. See OM, under AHC.

What you will gain with kings & LC T-bars:
Carry more load on coils & T-bar, result in low pressure on AHC (globes) rear & front. Which to much pressure, shorten life of globes.
AHC pressure failure, can result in dropping to bump stops. With Kings rear will not, LC T-bars front will not.

I would use 20mm donuts/spacers on the king, with max rear sensor lift. Kings alone are for stock height.

Look close, you'll see the index marks/points.

Bump on bracket, white mark on T-bar

Ok so that means turning the 30mm adjusting bolt until the front on both sides measures 19.75inch from fender to center hub? I do have a steel front bumper installed

Go thru the ABC’s thread again. The sensors are used to adjust height and the torsion bars are used to level from side to side and to correct AHC pressures.
