They are different fan clutches for different options installed on your Avalanche. You will need to check the RPO codes printed on the sticker which is likely located on the inside cover of your glove compartment. Next, check to see which codes match up to the description(s) located in the Notes box underneath the vehicle information that appears at the top of the Amazon page for each fan clutch.

Looks like one is for an Avalanche with heavy duty cooling, and the other is for an Avalanche with Automatic/Auxiliary AC control, an option for HD trailer equipment, a specific rear axle gear, etc.

Check out your RPO codes and make sure you get the correct fan. Not really complicated.

Good Luck!
