Toilet Flush Valve Kit With 3 1/4ft Flapper - Exact Kohler Replacement

In this review of the Toilet Flush Valve Kit With 3 1/4' Flapper, the bottom line is simple: this kit is for owners of Kohler Cimarron toilets who need an exact, reliable replacement to stop running toilets and restore original performance. The reviewer found the kit to be a genuine Kohler part that fits as intended and often resolves common flushing problems. It is not a universal part, so buyers should confirm compatibility, but for the right model this kit delivers an easy install and long-term reliability.

Key Features

• Kohler Genuine Part: Ensures components are engineered to Kohler specifications for original product performance and to protect warranty coverage.
• Complete Flush Valve Kit: Includes all valve components needed to replace a worn flush valve without sourcing extra parts, saving time during repair.
• 3 1/4' Flapper: The specific flapper size provides a precise seal and proper water flow for the intended model, which helps stop running toilets.
• Fits Cimarron Toilet class five: Designed to be a correct replacement for Cimarron class five toilets, avoiding fit issues common with generic parts.
• Manufacturer Model Match: Labeled with model number 1024385 so buyers can confirm a direct match to Kohler service parts lists.

Who It's For

This kit is best for homeowners, plumbers, or maintenance staff who own a Kohler Cimarron toilet and want an OEM replacement to restore factory performance. It suits anyone who prefers buying a Kohler GENUINE part to maintain warranty and long-term reliability rather than using a generic alternative.

It is not ideal for people with non-Cimarron Kohler toilets or those seeking a one-size-fits-all universal valve. Also, a small selection of customers noted tool size considerations during installation, so buyers without a 4 in wrench or basic plumbing tools may need to prepare accordingly or hire a technician.
