One of the most crucial settings when it comes to configuring a shocks absorber is setting up the ride height. Ride height is measured from eye to eye, and depending on the measurement, along with the spring rate that's selected, a certain amount of compression or rebound travel is available. According to Alston, street vehicles need more compression travel to maintain ride quality. Drag vehicles need more extension, or rebound travel, to help weight transfer. The VariShock directions provide specific directions on setting a baseline ride height. After that, it's all about selecting the proper spring preload and taking advantage of the shocks' adjustability to fine tune the setting.
