Product Details
Description
The Tuff Country 24989KN 4" Lift Kit is a complete, easy-to-install suspension upgrade for 2017–2022 Ford F-250/F-350 4WD with gas engines. Built by a trusted brand with 35+ years of suspension expertise, it delivers a balanced lift, improved ground clearance, and the capacity to run larger tires with confidence.
- Lift Height: 4" front / 3" rear lift for a commanding stance and enhanced off-road capability.
- Radius Arm Replacement: Replaces factory radius arms to eliminate the need for radius arm drop brackets while preserving ground clearance.
- 36" Tire Compatibility: Enables use of large tires (36" x 12.5" recommended) for improved traction and a bold street presence.
- Shocks Included: SX8000 shocks matched to the kit to deliver controlled damping and a smoother ride on varied terrain.
- Drop Pitman Arm: Included to maintain steering geometry and reduce bump steer after the lift.
- Rear Suspension Components: Heavy-duty rear blocks and U-bolts ensure secure axle positioning and reliable alignment.
- Hardware & Brackets: Includes a heavy-duty track bar relocation bracket and all necessary mounting hardware for a solid, durable install.
- Made in USA: Proudly manufactured in the United States with a focus on quality and fitment.
- Warranty: Backed by a limited lifetime warranty for long-term peace of mind.
- Installation Note: Factory length shocks must be replaced with extended shocks to properly install this lift kit. Extended shocks are available in the options.
Benefits you’ll notice include enhanced ground clearance for rough roads and trails, a wider stance that improves stability, and the ability to fit larger tires without sacrificing steering feel. The radius-arm design minimizes driveline binding and maintains articulation, while the included drop pitman arm keeps steering precise at height. This kit is designed for real-world use—whether you’re daily driving, towing, or chasing off-road adventures—delivering durable performance with Tuff Country’s signature reliability and support.
| Important Note | Factory length shocks must be replaced with new extended shocks to install this lift kit properly. Please choose shocks & boots in the "Options" fields above if you have not already purchased extended shocks. |
