Confirm compatibility by dimensions, not just model numbers
Ordered this for my Kohler San Raphael (2002). I was happy to finally find a replacement flapper specifically for my toilet model. I’ve been using universal flappers the last few years and they always eventually end up being too large and wobbly for my toilet, which leads to the constant running water issue. My exact model number was listed on the product listing and even on the packaging for this flapper, however it ended up being too small. I honestly thought I was losing my mind and kept trying different ways to make it work… but it’s simply too short. When installed it sits too snug and stays partially open. I tried repositioning it on the back multiple times and nothing fixed it. I can’t leave a bad review for this because the product seems very good quality and it was easy to install. It just didn’t fit. I did however return it and eventually found the correct part for my toilet, which was just a touch longer, and now everything works perfectly. Just a heads up to double check measurements, because even toilets from the same model line may require different flapper lengths depending on the year or configuration. Bottom line: confirm compatibility by dimensions, not just model numbers, to save yourself the frustration.

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.

Kohler PART GP1078440 FLAPPER (SHARK-FIN), 2 In, Red
WOW. Ordered the Kohler Flapper for my Revival 1 piece toilet. The old Kohler flapper was about 10 years old and was not leaking but I wanted to replace it. I shut off the intake valve and took off the old flapper. I measured the stainless steel chain and once that was done I installed the new Kohler flapper., Then I turned on the intake water valve. The entire installation took less than 5 minutes. Easy peasy. I always install original Kohler parts for my toilet. No adjusting, no trouble installing and always the right fit. Pay a few dollars more but never have a problem.

I had replaced both toilets with cheap, flimsy flappers figuring "it's just a flap of rubber, what could go wrong?" Well, pretty quickly I found out... both toilets randomly ran-on with an irritating trickle of water. As time went on, it happened more frequently until I figured I was losing significant amounts (A friend had a similar problem and the water company actually left him a note about the increase in his usage and guessed correctly that his toilets were running on like this, so it can add up, over time) Anyway, it's been close to a year and both toilets are now functioning perfectly.
