Was very difficult to install. The threaded rod and nut were seized and incomplete, making them very difficult to turn. My electric screwdriver that I use to extend the stabilizer bars couldn't do it, so I used the small wrench that comes with the kit.

Giving at least two stars because they are very heavy and seem to be very durableβ¦
