Install note: Per our video below, we recommend 2 spanner wrenches width of preload on the front springs.
Fitment note: What we’ve seen is there are some variations in bodies across the w-body platform, whether it be yearly changes or casting differences. With this you may have to clearance one of the top mounting holes for the front coilovers to fit all three studs on the top hat cleanly. Before installing check the clearance of the studs and make sure they don’t have stress from the body putting pressure on the stud.
