Cobra SZ 400 Offset drivers help square the clubface, making it easier to hit straight tee balls and prevents slicing. The all-titanium 400cc head has a thick rhombus-shaped center inside a thinner perimeter for maximum distance and forgiveness and a solid sound off the face. The King Cobra 400 SZ Offset driver has two back weights in the sole that shifts the center of gravity low and back for higher launch angles and improved club head stability on miss-hits.
