We present low temperature longitudinal magnetostriction measurements taken using a capacitance dilatometer in a PPMS-14 instrument for several RAgSb$_2$ (R = rare earth) compounds. The quantum oscillations in magnetostriction were observed up to temperatures as high as 25 K. These data are compared with the results of de Haas - van Alphen and Shubnikov - de Haas measurements. Using these data the uniaxial stress dependencies of the extremal Fermi surface orbits can be evaluated.
