- Fits 2005-2026 Ford F-250 - F-350 Super Duty Power Stroke
- Fits 2017-Present Ford F-450 Super Duty 6.7L Power Stroke
- Fits 2017-Present Ford F-550 Super Duty 6.7L Power Stroke
Important Fitment Notes:
- Designed for diesel-powered trucks only.
- Not compatible with gasoline-powered Super Duty models.
- Front axle load ratings may be reduced when installed on F-450 and F-550 applications.
- Sold as a pair.
- Coil springs only. This is not a complete leveling kit.
- Due to the amount of front lift these springs provide, alignment correction components are strongly recommended. Caster correction shims, aftermarket radius arms, or radius arm drop brackets may be required to restore proper alignment geometry and maintain optimal handling characteristics.
-
Any time ride height is altered, an adjustable track bar is recommended to properly recenter the front axle and maintain correct suspension geometry.

Description
The Axiom Supply Dual-Rate Coil Springs were developed for Super Duty owners who demand more from their suspension than the factory setup can provide. Whether your truck spends its time towing heavy trailers, hauling equipment, navigating rough job sites, or exploring off-road terrain, these springs are designed to deliver improved performance without sacrificing ride quality.
Unlike conventional single-rate springs, the dual-rate design provides a comfortable and controlled ride during normal driving while increasing support as suspension loads rise. This allows the truck to remain composed under heavy payloads, aggressive driving conditions, and demanding terrain.
Constructed from premium spring steel and finished with a durable powder coating, these coils are engineered to resist premature sagging and maintain consistent ride height for years of service. Extensive real-world testing has proven their ability to handle everything from daily commuting to severe-duty truck use.
Because these springs increase front ride height, proper suspension geometry should be addressed during installation. We strongly recommend using caster correction shims, aftermarket radius arms, or radius arm drop brackets to restore factory alignment specifications and maintain proper steering feel, tracking, and tire wear. Additionally, an adjustable front track bar is recommended to recenter the axle after lifting the vehicle and ensure optimal suspension performance.
Understanding the Lift Height:
Ford lowered the factory front ride height on 2020+ Super Duty trucks by approximately one inch compared to previous generations. Because of this change, the same coil spring produces different lift measurements depending on model year.
- 2005-2019 Super Duty: Approximately 2.5" of front lift
- 2020+ Super Duty: Approximately 3.5" of front lift
For 2020+ Tremor models, which already include a factory suspension lift, these springs typically provide approximately 1.5" of additional front lift.
