I have not tried extract mode. The highest mode would be extract with the link rods. The max I have taken it is off-road high. More than enough clearance. I would like to save my axles. Plus, not into trails over a 6. Paid too much to beat up my truck
The spacer are are well made. Installed 1.5 inch and lift to clear the 37/12.5/20 on stock core wheels. Runs great but need to do a range test. And will cut a little.
