This work is focused on the identification of cracking points in charged spherically symmetric stellar configurations in the vicinity of f(R) gravitational theory. To identify cracking points, the hydrostatic equilibrium equation is for the application of local density perturbation scheme. We apply local density perturbation technique to test the viability of 4U 1820-30, Vela X-1, and SAX J1808.4-3658 according to different physical parameters involved in model presented by Nazar and Abbas (Adv Astron 2021:6698208, 2021). It is concluded through graphical illustrations that cracking points help in the refinement of the stability regions by exhibiting cracking in different interior regions.
