Equatorial ridges are a feature of at least three of Saturn's moons: the large moon Iapetus and the tiny moons Atlas and Pan.
One theory is that these are remnants of Saturn's rings, colliding with the equator of these moons.
See: https://en.wikipedia.org/wiki/Equatorial_ridge

Several other theories are listed for Iapetus, including the suggestion that Iapetus had its own ring system.
