Note Regarding Front Shock Perch Setting
From the factory, your truck was set on Low Perch.
Low Perch provides the best ride quality and fuel efficiency, however it does set the nose of the truck down and makes the body roll in the corners more (less support from the springs).
Mid Perch is where SVT designed the truck to sit. Almost level with the back of the truck, the stance looks better overall. Also, with the front shocks on mid perch it does support the truck better in the corners, however because the springs are compressed an additional inch, the straight line drive is about 10% stiffer than low perch.
