GMC Sierra 2500 HD Suspension Leveling Kit - Zone Offroad - CV Spacer - 01-10. This CV spacer service kit is built to work with Zone Offroad 6-inch systems on 2001–2010 GM HD trucks, helping keep your front driveline geometry in check.

Designed for the 2500/3500 HD platform, this kit spaces the front CV joints correctly after a Zone 6-inch suspension install, helping reduce bind and promoting smooth 4WD function.
