Tilt-over hinged base - yes. Foldover tower kit - no.

You mean tilt-over from the base or foldover from up the tower? Many
towers can be tilted over from the base; some have hinged bases available,
others you'd need to engineer and fabricate. There aren't any that foldover
up the tower systems anymore since Rohn quite making the foldover kit.
Why do you want a tilt-over? Many amateurs feel that they want a
tilt-over to make it easier to work on the antenna or other stuff on top of
the tower. Unless you intend on doing lots of intentional antenna work
(design experimentation, etc.) where having a tilt-over capability to make
things easier, you shouldn't really have to "fix" anything in a properly
installed array for ten years or more. So having the tilt-over available is
kind of a false goal particularly with the high potential for mechanical
failure due to the tilt-over mechanism (especially if it's home-brewed). The
horizontal forces on a tilt-over system are LARGE and don't lend themselves
to typical ham "hip-pocket engineering".
Proceed with caution and follow the LXC Prime Directive - "DO what the
manufacturer says". And "DON'T do what they don't tell you".
