This kit fits 2001-10 2500 & 3500 HD models. Zone Offroad torsion bar key leveling kits are made in the USA and are 100% resonant frequency tested to ensure a solid casting. Once tested the torsion bar keys are CNC machined to achieve a 2" of lift. Only Zone Offroad lists torsion key fitment based on the RPO codes of your truck listed in the glovebox to ensure the correct fitment. No more guessing of what color key might have been installed from the factory. Shock relocation brackets or longer shocks are required and are listed in the recommended accessories.

Important Notes!

  • Rear u-bolts will not fit dually applications.
  • Front shock relocation brackets or longer shocks recommended.
  • To determine which kit # is required, verify which RPO codes are shown in the glovebox to determine the factory installed torsion keys. Any of the following RPO codes require the C1202/C1212/C31 kits: FT2 - FT3 - FT4 - FT5 - FT6 - FT7. Any of the following RPO codes require the C1203/C1213/C32 kits: FK2 - FK3 - FF6 - FF7 - FF8 - FF9.
