OA Staff is outstanding, Tyson even called me back at 7PM on a weekend!
I installed the Icon rear springs in the #2 option with a pair of drop shackles.
Front was Eibach springs and it has a nice stance to the truck. About 1.5" rake to the rear so I can still tow my trailer without the bumper sitting on the ground. I believe the Fox shocks were intentionally valved for these trucks with an upgraded spring in mind. With the stock setup, the truck had a lot of rebound chatter in both front and rear, gone is the sketchy lack of traction on washboard roads.. With the upgraded springs front and rear it now is a perfect ride over all terrain Best upgrade for the Raptor!!!!
