Use the Proaim 2-Stage Support Pole for Camera Sliders with 5/8 Baby Pin Ends when using a center-supported slider to provide extra support and prevent the ends of the slider tracks from flexing. The support pole is a simple and easy solution to eliminate this issue. It mounts at the ends of the slider which adds stability to the setup and prevents flex from messing up your horizons.
