3” Adventure Series Lift System. 

This ZONC31N is a new addition to the Adventure Series lineup of lift systems and is built around the Zone Offroad heavy-duty replacement upper control arms already available for the 01-10 HD trucks.  The arms are made from 3/16” steel that is precision laser cut, formed, and fully welded.  Preinstalled Raybestos brand ball joints and rubber bushings provide easy installation and long service life. 

The ball joint is repositioned to compensate for the added lift and maintain a neutral position at ride height.  To complement the improved upper ball joint angles, the kit address the other area often ignored at this lift height – the CV shafts.

Ask a Question
  • Are there any other parts required for this install?

    This is a complete kit and doesn't require anything extra.  The only thing you will need to do after is a wheel alignment.

  • Will this kit work with a kryptonite steering setup, from what i read the upper control arms cause an issue?

    This should be fine to run with any Kryptonite Parts
