American Standard Champion 4 MAX Toilet Tank Lid - AMS-735170-400

The 735170-400 is the American Standard replacement tank lid made for Champion 4 MAX toilets, so it drops onto that tank the way the original did. One caution before you order: toilet tank lids are cut to a single tank's opening and are not interchangeable across models, even within the same brand. Check the model on your tank (or the numbers stamped inside the old lid) and confirm you have a Champion 4 MAX rather than another American Standard series.

Two china colors. White is part number 735170-400.020 and Bone is 735170-400.021. It is the same lid either way, only the glaze differs, so order by whichever color your toilet already is. If you are replacing a cracked lid on an existing fixture, match the tank, not the seat or the bowl trim.

Yes. The Champion 4 MAX lid is sold on its own as a replacement top for the tank, so a chipped or broken lid does not mean pulling and rebuying the fixture. It lifts straight off for access to the tank interior when a fill or flush valve needs service, and sets back on the same way. For a property manager with several Champion 4 MAX units, it is the same part across all of them in a given color.

Vitreous china, the same glazed material as the toilet body, so it takes the same cleaners you already use on the bowl and carries the same sheen rather than reading as an aftermarket cover. That matters on a visible fixture in a unit turn or a guest bath, where a mismatched replacement top is the first thing anyone notices.

It is the vitreous china cover only. The lid conceals the working parts rather than carrying them, and comes off to reach the fill and flush valves inside the tank. If your trip lever, flapper, or fill valve is what failed, those are separate Champion 4 MAX repair parts and this lid does not replace them.
