Product review (5 stars): Perfect kit for our LG TROMM gas dryer
These dryer drum rollers and belt worked great to fix our LG TROMM dryer.  Since I was going in to the dryer for the fix, anyway, I decided on this kit with all 4 rollers and the dryer belt - it was cheap insurance to replace all that at the same time.  I did have to separately order the idler roller for the belt, and I think it would be good to have a version of this kit with that idler pulley, too, as that is another potential wear item that makes sense to replace at the same time.

I would also recommend to take a moment and vacuum out the accumulated lint and small items that wind up inside the dryer housing while the dryer drum is out to replace the rollers.
