Height Offset can adjust a maximum of .8", so you move the physical sensors first, and then you have .8 to play with.
Step 2: Prepare suspension. Check tire pressures, put transmission in neutral, Cycle height from LO to N 2 times, and bounce corners to “stabilize suspension”. All doors have to be closed for this, and I keep my driver window down to access the ahc controls (And laptop).
Step 3: enter Techstream, AHC, Live Data, and take a picture of your values before you mess with anything.
Height Offset Utility only changes the 4 highlighted values below:
With these numbers, my driver Front was 1/2" low.
Step 4: Start HOU. Select FL, enter measured value of "4.5", enter standard value of "4.0"
This will add .5 to your FL height adjust
FL height adjust went from -0.3 to 0.2. After this, I added another .5" adjust to get to 0.7 (and added the same to FR)
The maximum height adjust is 0.8.
Step 5: cycle through heights and measure again.
Step 6: slap on some 35"!!!
AHC Questions:
What initiates an automatic adjustment?
¼”, ½”, 1”, 2” slope?
Is automatic leveling only a front to back function or side to side as well?
I feel my front drop/raise all the time. Can the rig make this same kind of adjustment left to right? i.e. passenger side raises/lowers to meet the driver’s side?
Is the front primary? Meaning, the front always moves in order to compensate or can the rear adjust as well?
Does self-leveling occur at highway speeds?
Rig drops into “Fast Lo” Mode at 62mph. will the rig ever attempt to self-level during these speeds?
Does weight affect height? i.e. Does a full tank of gas affect rear passenger height?
This thread tells me no:
LX570 Lean/Sag
Does your mechanic know how to properly prepare AHC for alignment? In theory, if rig is on an incline and has attempted to self-level, could this affect alignment readings? Ideally, the alignment table is level, tech drives on it, raises the table, make sure you leave doors closed to allow rig to self-level, turn off AHC, then turn off car. Or none of this really matters for Alignment?
I’ve seen people mention measuring from wheel center to fender. Unless you cross-hatch the center cap, there’s potentially a bit of error here, right? I’ve been measuring top of center cap to fender or top of rim to fender.
Other helpful links I’ve come across, for reference.

- 1mm of movement on the sensor equates to 2mm on the rig.
- In theory, assuming there’s enough stoke in the shocks, you might be able to add .8” on top of the “sensor lift” method (move the screws to the bottom (front) and top (rear)).
