What would a world with uneven gravity look like?

If there was to be a habitable planet, similar to earth, but with varying gravity at different points on its surface - lets pretend that it varies from .8g to 1.2g - what sort of terrain or form would be necessary in order for this to exist? it would still need to have a large amount of liquid water, so mechanically a very tall mountain range would need to not fall under it's own weight (and ideally also have a breathable atmosphere at such heights). It could spin much faster on it's axis, and have some sort of Centrifugal force, which would reduce the gravity near the equator, but also mess up any sort of day/night cycle, and again, potentially the atmosphere. Are there any alternatives? some sort of weird but feasible planet geometry? a large moon that can reduce the gravity on the surface of the planet depending on it's position in orbit?
