Rock Krawler F2XF4006 4.0 Inch X-Factor Suspension System Lift Kit

The Rock Krawler F2XF4006 4.0" X-Factor Suspension System is a complete lift kit engineered specifically for Ford F-250 and F-350 Super Duty diesel trucks. Precision-crafted in-house, every component is designed to optimize factory geometry while delivering a dramatic improvement in both on-road comfort and off-road capability.

Key Features:

• 4.0" of lift height for increased ground clearance and larger tire fitment
• Tuned multi-rate coil springs engineered to work in unison for a smooth, controlled ride on the street and trail
• 4-Link front geometry that improves axle control, eliminates suspension bind found in conventional radius arm systems, and allows for significantly smoother articulation off-road
• Rear add-a-pack leaf springs precisely matched to the front coils to properly support the vehicle under load and towing conditions
• Fitment for larger tires — allows fitment of up to 38" tires
• All components precision-engineered in-house for maximum quality and fitment accuracy
• Compatible with diesel-powered Ford Super Duty trucks

Whether your truck is a daily driver, a weekend trail rig, or a heavy-duty workhorse, the Rock Krawler X-Factor system is built to perform across all conditions — street, tow, and trail. Note: Shocks are not included and must be purchased separately.
