Metalcloak's joints are 100% squeak free. Period. Its inherent in the design. There have been extensive arguments in the past about the longevity of the joints (mostly by a direct competitor), but they've been opened up after 20k miles of use to show negligible wear.

BUT, there are a lot of joints that don't squeak terribly. I just happen to have a couple years experience with a squeak-free metalcloak system and know that they will never squeak based on how they are made.
