Rated 4.0 out of 5.0 by windsurfer Exact replacement………….
Easy to install………….. Tip…...save the clips from the old key chain. The new clips on the replacement are difficult to use when, adjusting the length of the chain.

Rated 5.0 out of 5.0 by NewHomeownerKay Perfect part.
I move into a new place and sigh... I hear my toilet running throughout the night. Thanks to this part, my first repair as a new homeowner was a success. The chain is a little long but that will be an easy fix too. It's a perfect fit for a Kohler toilet so I recommend paying the extra .79 cents over the generic brand.

I tried generic flappers - those leaked.
Eventually read the label under the tank lid (Kohler 4620).
That referenced part no. 84225; That part no. has been superseded by GP85160.
Bought two at Home Depot. Problem solved.
The GP85160 is a little more flexible than the generic. Also, the nub under the flapper is a bit smaller. Spend the extra $$ and save yourself alot of frustration.

Rated 4.0 out of 5.0 by Racoon Replacement flapper began leaking again after 6 months
Six months ago, I replaced my flapper (Kohler-specified replacement) because the original flapper was failing after ~7 years of daily use. Its seal with the top of the toilet's main refill pipe was allowing tank water through, which would trigger the tank's refill valve. This was happening with increasing frequency (up to every 20-30 minutes) and its recurrence, accompanied by the 10 seconds of refill noise was really driving me nuts, when what I desired, had long-experienced and was expecting total silence from the WC.
Well, the replacement I got (this Kohler GP85160) seemed to work well, although its dimensions were indistinguishable from the original flapper. The replacement flapper appeared to have slight greater pliability, so I thought it would promise better performance. And it did. It worked fine -- until this past week, some six months later. The leaking past the seal and the triggering of the refill valve has begun again. Not as frequent as before, but that's not what I bought the replacement flapper for. I wanted a complete solution, not a short-term cease-fire. So off to Kohler I go.....

If you own a Kohler brand toilet, there are no substitute for this part.

Rated 2.0 out of 5.0 by HGOB Mixed feelings on my installation and the final outcome
My toilet was leaking too, so I purchased this flapper with the hopes it would also make it possible to keep the flapper up long enough for the water to go down the tank yet it was not to be.
I called Kohler and they explained to me that the float should at the midpoint of the lower and upper water levels.
Then it was advised that the chain not have any slack above or blow the float with a full tank of water. So after I adjusted every thing by cutting the chain for my particular needs I fine tuned the chain by bending the arm inside the tank. It was almost tight, e.g. just with a minimum of slack.
What is happening is that I must remain on the handle until all the water has gone into the bowl otherwise the flapper goes right down and prevents the water from doing it's job.
In addition the tank is still losing water so I followed up with some very fine steel wool on the plastic rim where the flapper rests. I haven't had an opportunity to check this out yet if it even helped.
This is where I stand right now.
As for the instructions they are a mish-mash because instead of putting English by itself the languages are interspersed making one to hunt the continuation of the installation.
So French in one spot, Spanish in another and English by it self. This would help a lot.
