  • Throttle Down Kustoms’ CJ3B Frames are built without the rear K-style crossmember. Instead, we use a 1/4 steel angle that is CNC water cut with the body mounts cut in. This is stronger than the stock K-style crossmember.


  • All frames are shipped bare metal.
  • Throttle Down Kustoms does not offer the stock battery box welded to the frame. The end user will have to reinstall the stock battery tray to the new frame.
  • Some stock running boards do not work the same. You may have to modify them to work.
