A cable for use in a remote control assembly includes a liner having a longitudinal axis along a length thereof and defining an interior. The cable includes a core element disposed and moveable within the interior and extending along the length. The cable additionally includes a sheath disposed about the liner along the length. The cable further includes a support layer mounted to and disposed between the liner and the sheath, with the support layer supporting the liner along the length, reinforcing the sheath along the length, reducing movement of the sheath with respect to the liner and vibrations caused during movement of the core element, and minimizing bending of the liner and the sheath about the longitudinal axis. The support layer is comprised of a resin material.
