KellTrac Ultra Spec Inverted Viking Crusader Shocks, Pair (KTI-KT3010U) - 2015–2026 Ford Mustang
The KellTrac Ultra Spec Inverted Viking Crusader Shocks are engineered for Mustang owners who demand the highest-performing double adjustable shock available for the S550 and S650 chassis. Built upon the legendary Viking Crusader platform, these shocks feature KellTrac’s ultra-specific valving designed to control a wider range of power levels, surfaces, and suspension setups than standard offerings.
To further enhance performance, KellTrac pairs its proprietary valving with spherical bearing lower axle mounts, allowing the shock to react faster and more consistently on launch. Combined with an inverted shock design, this setup delivers improved durability, increased clearance, and easier adjustability—making it a proven choice for serious street/strip, prep, and no-prep applications.
These shocks are recommended for enthusiasts who want elite performance and expert-level support—not for NVH-sensitive builds or show cars. The spherical bearing lower mounts can introduce additional noise or vibration, but the payoff is unmatched control and repeatability where it matters most.
