# Zone Offroad 01-10 GMC 2500/3500 HD 2in Torsion Bar Keys Leveling Kit

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.

-   Castings are resonance frequency tested to ensure they are defect-free and ready to withstand any abuse
-   Levels out the stance of your truck and allows clearance for larger tires to be installed
-   Front shock relocation brackets or longer shocks available
-   100% bolt-on design for easy installation
