Gas Spring Technical Info > K-Factor
K-Factor is the ratio of the compressed force (P2) and extended force (P1)
expressed as P2/P1.
As governed by Boyle’s Law, P2 force is always greater than P1 force. During spring compression, the volume of rod introduced into the cylinder displaces an equal volume of gas, increasing the pressure in the cylinder and therefore the force of the spring. IGS standard springs are manufactured to uniform K factors for each size (determined by rod diameter). Those factors are:

K factor’s can be increased or decreased to optimize performance See the following section on Modified K-Factors.
