Common Applications and Problem Solving

• Improves ride stability and control on Ford F-150 trucks
• Reduces shock fade during heavy towing or off-road use
• Addresses suspension sag and poor damping response
• Enhances suspension travel for rough terrain handling
• Replaces worn or damaged factory shocks for restored performance

Installation Notes and Tips

Ensure compatibility with your Ford F-150 model year before installation. The eye 12mm upper and lower mounts correspond to factory mounting points, allowing for a direct replacement. No adjustable damping means no tuning is required post-installation. Verify that the remote reservoir is securely clamped using the included billet clamp to prevent movement during operation.
