To the best of my knowledge, didn't Ford use class 10.9? If so, would these be weaker? I am not trying to be cheeky, I am legitimately asking. - Joe 5 years ago

Ford did use 10.9 and did so because they must exceed their failure testing by a certain margin. Based on inferred load and rotational torque spec, the 8.8 is more than sufficient. - Jonathan 5 years ago
