The spring configurations we use will vary from vehicle to vehicle, sometimes even from rider to rider depending on several factors such as intended use or rider weight. The number of springs used can vary to modify the progression needed to address issues on a specific vehicle or to achieve certain ride characteristics. We often use small softer springs on top (often called tender, helper or zero-preload spring) to provide some initial plushness and a combination of other springs to control variables such as body roll, resistance to impacts and bottoming.
