Product review (5 stars): Replaced LG dryer drum after it developed crack
These don't come with the triangular plastic clip collars so be careful when you take off the old ones. The old ones will bend quite a bit but just be careful. These replacements are a different color than the original but did the job. I was tempted to not replace the rollers at all but did find some significant damage to one of the rollers, plus might as well replace them after seven years of use.  I also vacuumed all the dirt that had collected in my dryer.
