Wanting to see how many have lifts that sag in the front after install. Let us know what lift you have, how many miles on it. If you corrected it let us know what you did to fix it. Seems that this may be focused on Toytec 884 coil springs. Tell us if you have the Rear spring TSB.
I just installed the 3" toytec with 884 coils and 1.5" block and had the TSB done the day before I installed the lift. Max of 200 miles on the lift at this time. Still level.
