Product Details
Description
Upgrade your 2008–2016 Ford F-250/F-350 4WD with the Tuff Country 24975KN 4" Lift Kit. This complete suspension package combines replacement radius arms, coil springs, rear blocks, U-bolts, and SX8000 shocks to deliver a reliable, performance-focused lift that’s ready for both daily driving and off-road adventures.
- Lift height: 4" front lift with a 3" rear drop, engineered to balance stance and ride quality on heavy-duty pickups.
- Replacement radius arms: eliminates the need for radius arm drop brackets to preserve ground clearance and maintain factory-like alignment geometry.
- Coil springs: heavy-duty coils designed to work with the 4" lift for consistent ride height and weight handling.
- Rear blocks and U-bolts: secure, durable mounting to support the rear axle with the lifted stance.
- SX8000 shocks: included shocks deliver improved damping, stability, and control across varied terrains.
- Pitman arm and track bar relocation bracket: optimized steering geometry and axle centering to maintain predictable handling at height.
- No radius arm drop brackets required: preserves ground clearance and reduces undercarriage interference for better off-road clearance.
- Important installation note: factory length shocks must be replaced with extended shocks to install this lift kit properly; consider extended shocks and boots in the options if you haven’t already.
- Made in the USA: proudly manufactured in the United States, reflecting Tuff Country’s long-standing commitment to quality and durability.
- Warranty: covered by a limited lifetime warranty on lift kits, providing lasting peace of mind.
This kit is designed to fit Ford F-250 and F-350 4WD models from 2008–2016 and is compatible with up to 36" tires (recommended size 36" x 12.5" when paired with appropriate wheels). By replacing factory geometry with purpose-built radius arms, this kit minimizes alignment surprises and keeps steering predictable as you tackle rough terrain. The combination of reinforced coils, sturdy rear blocks, and SX8000 shocks creates a balanced, controlled ride that doesn’t compromise on ground clearance or durability. Whether you’re chasing weekend trail adventures or upgrading a daily driver for a tougher, more capable footprint, this Tuff Country lift kit provides a reliable, value-forward path to a taller, more capable truck.
| 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. |
