Elastic scatterings of the $^{6}$Li + $^{92,94,96}$Zr systems at $E_{lab}$ = 70 MeV have been analyzed within the framework of the Coulomb-modified Glauber model by using the effective nucleon-nucleon ($NN$) amplitude having the higher momentum transfer components. The calculated results, taking into account the effective $NN$ amplitude, show excellent agreement with the observed data. Once the parameters of the effective $NN$ amplitude have been determined from the $^{6}$Li + $^{94}$Zr elastic data, the theory nicely reproduces the $^{6}$Li + $^{92,96}$Zr elastic scatterings at the same energy. We investigate the effects of the higher-momentum transfer components of the $NN$ amplitude on the angular distributions, the phase shifts, the transmission functions, and the reaction cross sections. We found the introduction of the higher-momentum transfer components of the $NN$ amplitude to be important in the description of $^{6}$Li + $^{92,94,96}$Zr elastic scattering data, especially at large scattering angles.
