Competition only valved specifically based on the vehicle and the use (drag, pro-touring/time attack)
The patented Viking Crusader shock absorbers and struts were developed based on requests from the pro-touring community, along with the small tire and high horsepower drag race customers. With these vehicles, there are situations that require rebound forces in excess of what standard passive adjustable shock absorbers and struts can provide. The other factor in our design parameters was the frustration that adjustable shocks and struts, in general, are too complex for the average person to be able to revalve.
From these requests, the Crusader was born. These shock absorbers and struts have various valving options dependent on the vehicle use and vehicle specifications. The Crusader is available is either a double adjustable shock, with independent compression and rebound tuning or a triple adjustable where the compression adjustment is separated into low-speed and high-speed adjustments. The rebound valving has a progressive curve that is strictly determined via orifice control. A progressive valve will have a softer low speed force that ramps up very quickly as shaft speed increases. However, do not let this description deceive, as these shocks and struts can generate huge forces at low speeds, depending on the needle and seat combination selected. In fact, this line of shock absorbers and struts produces forces far greater than nearly all others on the market. Depending on the needle and seat combination selected, the adjustment range can cover a very large range or a more narrow range with very small defined increments.
These patented shock absorbers and struts feature an interchangeable needle and seat design. The rebound valving adjustment range can be changed without completely disassembling the shock absorber. With the shock or strut in a vice on its side in the fully extended position, the rebound knob can be taken off, and the needle and seat combination can be changed out. This can be accomplished with basic hand tools. There are no expensive “special tools” required to be purchased from Viking. The process is similar to jetting a carburetor. Obviously, it is critical that everything be kept extremely clean, as there are very small orifices that must be kept free of debris.
Please note that Crusader shocks are intended for "Competition Only" applications and are NOT intended for street use. When vehicles are off-track or being trailered, they must be set at Viking's specified off-track settings.
The Crusader rebound valving has a progressive curve, which can generate significant forces. There are various standard rebound valving offerings depending on the vehicle use and the vehicle specifications. The rebound valving options are the same whether you select a double adjustable or a triple adjustable.
The Crusader compression valving is available in either double adjustable or a triple adjustable. The double and triple compression valving options for the Crusader Series are the same as the Berserker Series. Please reference the compression graphs above under the Berserker Series.
It has been discovered that the lower coil spring seat may come in contact with certain aftermarket half shaft boots and or shortened sway bar links. Clearancing the lower coil spring bucket may be required.
