Perfect fit, easy to install
After researching the correct current part number for my Kohler toilets, I found these at a very good price on Amazon. I was happy to see that they were genuine Kohler parts and packaging. Easy to install and they have been working perfectly.Those who are giving low ratings because these aren't the right parts for your models, I think that's really unfair. Do the research to find the right replacement parts. You can't expect a miracle from something that wasn't designed to fit. I don't even know the name of the toilet model that I have, but I found the replacement parts information on a sticker on the interior tank lid. A simple search of the part number at Kohler's site indicated the new part number, which I then found on Amazon.

Worked with my Kohler Toilet, but chain is too short
This flapper was easy to install and fit my toilet. Unfortunately, the chain was too short, so I had to use the chain from the old flapper to make this new one work with my toilet.

Worked perfectly for my Kohler toilet to stop a slow leak
Our water tends to be a bit hard so these rubber parts tend to breakdown every few years. I had some trouble i the past using the cheaper/generic one size fits all replacement stopper from the local big box store so now I just order these brand name ones for the 2 fancy Kholer toilets on our home as they work better than the generic and they are a bit cheaper than buying locally but more importantly show up at my house. I still use the generic for other toilets though.

Original product
I really like that Amazon carries the original Kohler replacement flapper. These are great and just like the ones you are going to have to replace sooner or later and they last longer than other brands. Great price too

Lasted less than 3 years
I'd hoped the OEM part would be better than the knockoffs, but this is already leaking.OTOH, it's easy to replace, not particularly expensive, and the shark fin design prevents jamming up and mis-seating pretty well.This style fits a rectangular overflow tube that's about 2 1/4 inches wide. the flapper body is 3 inches wide, but is called a 2” flapper.
