Steeda Rear Ride Height Adjustment Kit for 05-12 Mustang with D-spec Shocks ( no springs) - 555-8126

Ready to step up to an adjustable suspension setup on your 2005 and up Mustang? Buy the one with the most research and engineering, and all out track testing behind it. Designed and engineered in the U.S.A!

Steeda's billet adjustable suspension system for the S197 Mustang includes custom designed adjustable front struts and matched QA1 rear shocks which feature infinite simultaneous adjustment of compression and rebound. Not partial or no adjustment like other lesser kits.

The front coil over system is designed to use our exclusive upper strut mount kit which eliminates the weak factory upper spring perch which is prone to 'popping with increased spring rates and provides +/- 1 degree of camber adjustment not available with the factory mount.

The rear system features ride height adjusters for the rear of the vehicle which accept a coil over style spring, and QA1 shocks.

Two complete kits are available depending on whether you have already upgraded to our 555-8120 upper strut mount kit, which only requires replacing the upper spring cup, or you have the factory strut mount.

This kit is made from billet aluminum in our in house manufacturing facility and features anodized parts for long lasting protection against oxidation and roller bearings to make adjustments a snap. Fully adjustable for shock valving and ride height. Ride height adjustment varies based on spring rate but typical adjustment range available is stock ride height down to a full 2 inch lowering.

Note: Kit does not come with springs but please choose spring option form the drop down.

Steeda Adjustable Suspension System is used by winning racers and record breakers like:

• Robin Burnett
• Sutton High Performance

Voyager Series Shocks and Struts
The patented Viking Voyager™ double adjustable shocks have a digressive force curve with a fixed bleed for compression and a soft progressive rebound. This provides for softer, linear low-speed forces for maximized ride comfort. All Voyager™ shocks are equipped with a bump stop. Also, forces quickly increase at higher shaft speeds. This allows for adequate vehicle control to handle various road events. The Voyager™ series is unique, as it is a double adjustable shock designed solely for cruising. With many multi-purpose adjustable shocks, the tuning range for cruising is limited to a few settings on the softer adjustments, whereas the Viking Voyager™ provides a large, tuneable adjustment range specifically designed for cruising, allowing numerous options to dial-in your particular desired ride quality.

Viking Shock / Strut Features:
-Lightweight aluminum twin-tube design with a sleek clear anodized finish.
-Adjustment knobs: Labeled with a “C” for compression and an “R” for rebound with distinctive clicks. The triple adjustable also has a 1/8" hex for high-speed compression adjustment.
-Each click on the adjustment works and makes a change. There are no dead clicks. That is why all Viking tuning recommendations are from full soft. Other shock brands often recommend tuning from full tight, as often the first 10+ clicks provide no changes to the valving.
-By not offering non-adjustable or single adjustable, Viking is able to maximize stroke for each body length, ensuring you get the most travel out of your shock or strut.
-Aluminum, precision machined piston with a deflective disc and a P.T.F.E. / bronze piston seal.
-Hard chrome plated, centerless ground piston rod (shocks utilize a 5/8" rod; struts utilize a 7/8" rod).
-Three-step sealing system.
-All shocks and struts can be rebuilt or revalved by the Viking factory or any authorized rebuilder. CrusaderTM rebound valving range may be easily revalved by the user.
-In coil-over shocks, Viking provides bearing mounts as standard, not the less expensive poly mounts. Bearings perform better in supporting the weight of the vehicle and provide for misalignment when needed, thereby relieving unneccesary stress on the piston rod and seals. They are also very durable and don't break down like poly mounts do over time.
-In bearing mount shocks, Viking uses stainless steel bearing races, not inexpensive nylon race bearings like some competing brands.
-Left hand threads between the base and the body ensures that the shock/strut doesn’t come apart when adjusting the ride height, as can occur with certain other brands.
-Viking's double adjustable shocks and struts are priced close to the single adjustable price of most other manufacturers. Viking triple adjustable shocks and struts are priced close to the double adjustable price of most other manufacturers. Viking focuses on independently adjustable compression and rebound shocks and struts only, which means a lower price for you!
-Two year materials and workmanship warranty.
-Each shock and strut is hand built, tested, and serialized in our Lakeville, Minnesota factory.

Crusader Triple Adjustable Shocks and Struts
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.
