I run an Icon setup on my 07:
Love the setup.
I've ran both nitrogen charged shocks (Icon, Bilstein, etc..) and plain generic white bodied hydraulic shocks and IMO the nitrogen charged shocks perform much better.
We offer a few kits:
BDS Dual Steering Stabilizer Kit - 2005-2008 F250/350 4wd - Steering Stabilizers - Truck Toyz Store
Rize Industries Dual Steering Stabilizer Bracket Kit - 2005-2008 FSD 4wd - Steering Stabilizers - Truck Toyz Store
Icon Vehicle Dynamics 2005-2008 FSD Dual Steering Stabilizer Bracket Kit - Steering Stabilizers - Truck Toyz Store
Icon is the most money, but it's the cleanest looking when installed with the billet clamps that they use on the tie rod.
