If you want to transform your first-generation Super Duty with improved articulation and aggressive stance, this configuration stands out. The Rough Country 49370 lift kit is engineered specifically for the 1999 Ford F-250 and F-350 Super Duty 4WD platform.

πͺ 4-Link Suspension Advantage
The 1999 Super Duty platform uses a solid front axle with radius arms. While strong, radius arms restrict suspension articulation.
A 4-Link suspension separates upper and lower control arms. That allows improved axle control during suspension travel.
Benefits include:
This design enhances handling on both highway and trail.
It provides improved axle positioning during acceleration and braking.
π Six Inches of Height and Stance
Six inches of suspension lift dramatically changes the appearance of a 1999 Super Duty.
Increased ride height improves ground clearance and approach angles.
Many owners install 35-inch tires with proper wheel offset. Always confirm tire and wheel specifications before installation.
The truck gains improved undercarriage protection and aggressive styling.
This Lift Kit enhances both visual impact and capability.
π― Shock Performance and Ride Control
This configuration includes performance-tuned shocks designed for lifted applications.
The shocks are engineered to accommodate increased suspension travel.
They provide:
-
Balanced compression and rebound control
-
Stable highway handling
-
Reliable daily driving comfort
-
Improved control during moderate off-road use
While not adjustable, the dampers are tuned for predictable performance.
This setup provides consistent ride quality for older Super Duty builds.
π Towing and Heavy-Duty Applications
The 1999 Super Duty is known for durability and towing strength.
The 4-Link geometry maintains improved axle alignment under load.
Rear lift blocks help preserve rake for trailer stability.
