To create a more linear air spring curve, we needed to balance the negative air volume, air spring shaft size, piston surface area, and positive spring air volume. To create a more linear air spring curve, we moved to a twin-tube design to decrease the piston diameter and reduce the ratio between the piston and air spring shaft diameters. We further reduced the ratio by growing the traditional 10mm air spring shaft to 14mm, and made it hollow to expand the negative chamber. A smaller piston area requires more air pressure against the piston to give you the same amount of support in the air spring.
