A Spring link (10) for a vehicle suspension, extending along an axial direction (x) and comprising a bottom (4) extending axially and in a transverse direction (y) and, at its both transverse sides, side structures (5) extending axially and along a height direction (z), and being connected with each other only at their bottom side, a wheel-side mounting portion (7a, 7b) and a vehicle-side mounting portion (8a, 8b) at its respective axial end portions (7, 8), and a seat (S) for spring/damping means arranged axially between the axial end portions in a transversely outwardly bulged middle portion (6) of the bottom (4), and an intermediate portion axially at a transition into the bulged middle portion, wherein at a first portion (11) axially closer to the intermediate portion than to the center (13) of the bulged portion, an inertia ratio defined by the area moment of inertia effective for bending in height direction divided by the area moment of inertia effective for bending in transverse direction of the cross-section of a side structure taken alone is lower than 1.8, preferably lower than 1.4, in particular lower than 1.0, and/or an upper half inertia ratio being the inertia ratio of only that part of the cross-section of one/the side structure having passed beyond half of its height, taken alone, is lower than 0.36, preferably lower than 0.32, in particular lower than 0.28.
