KellTrac Ultra Spec Inverted Triple Adjustable Viking Crusader Shocks, Pair (KTI-KT6010U) - 2015–2026 Ford Mustang
The KellTrac Ultra Spec Inverted Triple Adjustable Viking Crusader Shocks represent the absolute pinnacle of rear shock performance for the S550 and S650 Mustang platform. Built upon the legendary Viking Crusader architecture and refined with KellTrac’s ultra-specific valving, these shocks are engineered to control a wider range of power levels, track conditions, and suspension setups than any conventional offering.
Featuring a true inverted design and spherical bearing lower axle mounts, this system allows the shock to react instantly on launch while dramatically improving durability and clearance. Combined with triple-adjustable valving, these shocks give experienced tuners unmatched control over rebound, compression, and high-speed characteristics—making them the preferred choice for racers who demand maximum performance and repeatability.
These shocks are designed for drivers who want the best technology, the best results, and expert-level support. They are not intended for show cars or NVH-sensitive builds, as the spherical bearings may introduce additional noise or vibration. If performance is your priority, these are the shocks that deliver.
