Show original supplier description
The KellTrac Viking Crusader "Ultra" Spec shocks, part number KTI-KT358U, are engineered as a double-adjustable shock for 2015-2026 S550 Mustangs. These shocks are specifically valved by KellTrac for optimal performance in STREET, STRIP, PREP, and NO PREP racing scenarios, utilizing an S550 IRS application. They are noted to have moderate NVH (Noise, Vibration, and Harshness). The product information suggests that for optimal performance, aftermarket upper shock mounts are highly recommended, and options for MagneRide compatibility are available. It is important to note that KellTrac orders typically ship within 2-4 weeks, with potential delays up to 6-8 weeks due to the custom nature of their products. KellTrac charges a 20% cancellation fee for orders cancelled before shipping and does not accept product returns. They offer limited remote support for all shock, strut, and coilover purchases. The product is not intended for "car show" use, but rather for dedicated performance driving.
