Shocks or Brackets Required: Factory shocks don't allow adequate suspension travel once lifted, shock extension brackets or aftermarket (longer) shocks are strongly recommended.
To determine which kit # is required, verify which RPO codes are shown in the glovebox to determine the factory installed torsion keys. The following RPO codes require the C1202/C1212/C31 kits: FT2 - FT3 - FT4 - FT5 - FT6 - FT7, while RPO codes FK2 - FK3 - FF6 - FF7 - FF8 - FF9 require the C1203/C1213/C32 kits.
