Maybe changing setting traditional to true might help. Here is (modified) code that I used to post unique identifiers (Guids) to the controller action.

var yourArray = new Array();
// TODO: fill array with ids of checked checkboxes
$('.CBC:checked').each(function () {
   yourArray.push($(this).attr('myId'));
});

var postData = {
    yourArray: yourArray
};

$.ajax({
    type: "POST",
    url: "/ctrl/ActionName",
    data: postData,
    success: function (result) {
    },
    datatype: "json",
    traditional: true
});

In the controller I have following action.

[HttpPost]
public ActionResult ActionName(List yourArray)
{
    return View();
}
