Fact of the matter is: The OE specified shocks on the IFS Torsion Bar trucks are barely long enough at stock height.
I went to full crank, and backed off 5 turns... My Bilsteins were fully extended. I then took off the lower shock mount nuts, and the front end popped up! The shocks were actually limiting the ride height. The torsion bars were pulling the shocks against their fully extended stops!
I put shock spacers in, my ride quality came back, suspension droop and travel came back. I then was able to go right upto one turn off of full crank.
I then pulled off one swaybar endlink, and turned it into a disconnect.
ON-ROAD capability of my truck is smoother, and handles better than stock - with no negative effects.
OFF-ROAD capability is incredible with the swaybar endlink off. The ride is SO SMOOTH, it feels like a Cadillac.
I went out with a guy on the weekend with a stock FX4, upto the local radio tower, It was 14km of rough, washboard, shale, rocky road. I had to keep waiting for him.. I took him for a ride, and he was in AWE at the ride quality of the truck.
