You can try this:

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
  if (comboBox1.SelectedIndex > -1)
  {
    string value = comboBox1.Items[comboBox1.SelectedIndex].ToString().Substring(4);
    this.BeginInvoke((MethodInvoker)delegate { this.comboBox1.Text = value; });
  }
}
