Description

Part Number: KTI-FDS15RS

After tremendous success with our S550 Front Struts paired with our spec Viking rear shocks, we decided to combine the two and offer it as a kit to take the guesswork out of it for you! This combination has been proven down to low 1.2 sixty-foot times on average prepped tracks, and 1.3 sixty-foot times on puddle burnout (only) asphalt streets! 

Please see below for details on the front struts and the rear shocks.

FRONT STRUTS:
These KellTrac S550 Mustang Mustang industry-first Adjustable Drag Struts for the S550 Mustang were designed, tested and revised for over 1-year! We have taken what we have learned since 2014 and implemented it all into this strut, making it the most powerful and most broad adjustment ranged Single Adjustable Drag Strut ever! By working with one of the world's leading shock manufactures we were able to develop drag race specific compression and rebound valving that is unlike any other stock replacement strut valving on earth! Gone are the old days of wanting a car to "pop wheelies", and gone are the old days of "picking and choosing" a valving that may or may not work. These adjustable KellTrac struts will work on most all drag-race oriented applications, from 7-second heads up racecars to 12-second bracket racing applications.


FEATURES:
-Designed to be a stock replacement strut for street/strip use
-Increased extension travel over stock struts
-Adjustable Valving based on power level and surface conditions
-Retains front sway bar, if needed
-Works with OE or aftermarket upper strut mounts and springs
-Designed around OEM fitment specifications
-Constructed of high quality strong steel material
-Quality coating to resist corrosion
-Zero NoiseVibrationHarshness Increase
-Industry First drag race specific adjustable drag race oriented stock replacement strut!

BENEFITS:
-Promotes more traction when adjusted properly
-Allows for more power to be applied due to increased suspension travel
-Allows user to adjust to various conditions
-Helps prevent excessive wheelies in applicable scenarios
-Helps Reduce Wheel-Hop
-Improves Handling, Traction and Feel
-Retain stock style springs!
-Simple installation

REAR SHOCKS:
The KellTrac Ultra spec Viking Crusader shocks are physically similar to and built upon the legendary Viking Double Adjustable Crusader shocks but have our very specific valving to handle a wider range of applications. In addition to our spec valving, we use a spherical bearing lower axle mount to ensure the shock can react sooner upon launch. When pairing our specs with the bearing lower mount, there is no other double adjustable shock for the S550 Mustang that has been proven to perform better!

This shock is recommended for those who simply want the best shock and tech support available. This shock is NOT for the car show crowd nor for the person who jumps and panics at every little creak and squeak the vehicle makes. The lower bearings on these shocks can add some NVH that may not be acceptable to some.

KellTrac Ultra Spec Viking Shocks are the most powerful and best performing double adjustable shock offerings available; FACT.

NOTE: For optimal shock performance we highly recommend aftermarket upper shock mounts
