The rebound valving, however, is a progressive valve that is strictly determined via orifice control. A progressive valve shock will have a softer low speed force that ramps up very quickly as shaft speed increases. Do not let the definition fool you, as these shocks can generate huge forces at low speeds depending on the needle and seat combination. In fact, the Crusader shock absorbers produces forces far greater than nearly all other shock absorbers on the market. The rebound side has 22 available positions of adjustments, the zero position and 21 distinctive clicks. As a result, the Crusader line provides for 418 different valving combinations. This needle and seat combination allows for a very large adjustment range.   You will not find anywhere near this broad of an adjustment range with high-end monotube shocks. Another important characteristic of the Viking shocks is that every click of the adjuster makes an actual change of the force output. While this seems like a no-brainer, there are many high-end shock absorber brands that do not change the force output until 12 clicks or more of the adjuster, which makes tuning on the car quite difficult. Another very cool feature to these patent pending shock absorbers is the interchangeable needle and seat design. The rebound valving adjustment range can be changed without completely disassembling the shock absorber. With the shock in a vice on its side in the fully extended position, the rebound knob can be taken off and the needle removed with basic tools and the seat changed out with a flat-head screw driver. The end user can choose from a variety of progressive force ranges. Viking has developed application specific valving for drag racing and pro-touring, where high force rebound is required. Multiple other valving ranges are also available.     Tech Note: Due to OEM design of the lower rear shock mount and the general articulation of the rear suspension, you may experience more noise compared to stock shock design. Viking Double Adjustable Shocks use poly bushings instead of rubber bushings in which a potential noise issue is possible. SHOCKS ARE NOT RETURNABLE AFTER INSTALLATION.
