The way the system works, the dealer has to look up a VIN to get the original build info and then sells you what the truck was built with. In other words, your VIN will get you the same bar rate that you already have. The only way to fool them is to use a VIN from a truck that was factory equipped with the bars that you want. Luckily for you, that has already been done by R-F members in the past.
These are the part numbers that they came up with:
1 code torsion bars:
F67Z-5B326-FB Drivers side bar
F67Z-5B326-FA Pass side bar
B code torsion bars:
F57Z-5B327-A Drivers side bar
F57Z-5B326-A Pass side bar
