This style wiper blade was originally fitted on Volvo XC60 models starting in mid 2011. Volvo later superseded all the earlier XC60 models to this style wiper blade and arm. The wiper arm and blade combination are interchangable as long as you replace them together and match the blade to the arm.
The easiest way to tell them apart is by looking at the arm. This is the later style blade for the "bent" style arm. The earlier cars used a straight arm.
If your XC60 already uses this bent style arm this blade is a direct fit. If your car uses the earlier straight arm and you want to use this updated style blade you'll also need to change to the updated style arm (see related products tab).
