7" 2023-2026 Ford F250/F350 4WD (w/gas engine) Lift Kit by Zone

Zone Off-Road F139F/F139N Reinforced Radius Arm Bracket Kit improves suspension geometry, ride quality, and handling on Ford F-250 and F-350 Super Duty gas-engine models. Designed for single-rear-wheel applications, this system corrects front-end geometry on lifted trucks to restore factory-like driving characteristics while maintaining increased ride height and capability.

At the center of this system are heavy-duty, reinforced radius-arm drop brackets engineered to correct axle rotation and return caster angles to factory specifications. By lowering the radius arm mounting points, the kit reduces coil spring bowing and ensures proper spring seating, resulting in improved ride comfort, steering stability, and consistent handling both on-road and off-road.

Additional components, including a forged pitman arm and heavy-duty track bar bracket, are included to maintain proper steering geometry and re-center the front axle after lifting. Full-length front coil springs provide a smooth, controlled ride while supporting the demands of gas-powered Super Duty trucks used for daily driving, towing, and off-road use.

This system is available with multiple shock options to match performance needs. The Zone Nitro Series twin-tube shocks offer reliable, everyday performance, while the FOX 2.0 Adventure Series monotube shocks provide improved damping control and off-road capability with fade-resistant performance. Together, these components deliver a balanced suspension system built for durability, control, and confidence in any driving condition.
