Built Around Geometry Strength And Real World Performance

The X-Factor 3.5" Suspension System is a full-featured upgrade built specifically for 2017–2022 Ford F-250 and F-350 4WD gas trucks. It includes triple-rate coils for both the front and rear, which deliver progressive performance across changing loads and surfaces. The system’s solid steel 4-link arms use 2-inch outer diameter tubing and 1 3/8-inch shank Krawler joints for unmatched strength and articulation. Paired with control arm drop brackets and an adjustable front track bar, the suspension maintains ideal alignment and axle positioning after lift. Add-a-pack rear springs provide a boost in towing and load support without upsetting the ride, while front and rear sway bar links are adjustable for fine-tuning on-road balance or off-road articulation. Bump stop extensions and U-bolt assemblies round out the setup to ensure safety at full suspension compression. Whether you're upgrading for aesthetics, trail performance, or work-ready reliability, this system is engineered to support it all with durability and precision.
