Show original supplier description
The Viking Crusader shock pair is a double-adjustable suspension upgrade engineered with KellTrac-specific valving for S550 IRS Mustang platforms. These shocks provide flexible performance tuning, making them suitable for vehicles ranging from dedicated racecars to weekend warriors that see occasional street use. The design offers a balanced approach to NVH (Noise, Vibration, and Harshness) for performance-focused handling. To ensure optimal performance and longevity, it is highly recommended to use aftermarket upper shock mounts with this kit. Proper installation is critical to achieving the intended dampening characteristics and handling improvements across different racing surfaces, such as prepped tracks or regular street driving. All KellTrac spec shock purchases include limited remote support to assist with the setup process. Please note that this product is tailored specifically for the S550 independent rear suspension geometry; verify your vehicle's specific requirements before installation to ensure compatibility.
