In this paper, we develop a new class of analytical solutions describing anisotropic stellar structures of observed neutron stars using modified  f ( T ) gravity. We use the off-diagonal tetrad that is best suitable for studying spherically symmetric objects in  f ( T ) gravity. We develop exact solutions in the quadratic model of  f ( T ) gravity by introducing physically reliable metric potentials that can describe a wide range of astrophysical systems. We then apply the model to investigate the stellar structures of four observed compact stars, 4U 1538-52, J0437-4715, J0030+0451, and 4U 1820-30. We calculate the values of model parameters for the stellar objects under examination in this paper. Comprehensive graphical analysis shows that the model describing anisotropic stellar structures is physically acceptable, causal, and stable. The model inherently exhibits the quadratic equation of state that can be utilized to investigate the material composition and stellar structures of the observed compact stars.
