You have F torsion bars (and code 3 leaf packs out back). F's are the softest factory Ranger T bars, B's are medium and #1's are the strongest/stiffest riding. Changing from F's to 1's is a big jump and would work best only if you're adding a lot of weight to the front end.
Part numbers for the #1 bars:
F67Z-5B326-FA Pass side bar
F67Z-5B326-FB Driver side bar
