💪 4-Link Suspension Geometry
The factory Super Duty uses a radius arm suspension. That setup limits independent axle movement.
A 4-Link suspension separates upper and lower control arms. That improves control during suspension travel.
Benefits include:
-
Increased off-road articulation
-
Improved steering precision
-
Reduced suspension bind
-
More consistent caster alignment
This geometry enhances both trail capability and highway stability.
It is ideal for lifted builds that demand more control.
🎯 V2 Monotube Shock Performance
V2 shocks are monotube dampers designed for enhanced control.
Advantages include:
-
Faster damping response
-
Better heat dissipation
-
Reduced shock fade
-
Improved ride stability
Monotube construction separates gas and oil chambers. That improves performance during demanding driving.
Compared to twin-tube systems, V2 shocks deliver firmer and more responsive handling.
This configuration provides upgraded performance without moving into adjustable reservoir systems.
🌄 Six Inches of Height and Clearance
Six inches of suspension lift dramatically improves stance and clearance.
Increased ride height enhances approach and departure angles.
Many owners install 35-inch tires with proper wheel offset. Always confirm wheel and tire fitment before installation.
The truck gains improved undercarriage protection and aggressive styling.
This Lift Kit enhances both appearance and function.
🚛 Towing and Heavy-Duty Capability
Super Duty trucks are built for towing and hauling.
The 4-Link geometry maintains proper axle alignment under load.
Rear lift blocks preserve rake for improved trailer balance.
V2 monotube shocks improve rear stability when hauling heavy equipment.
This suspension upgrade supports both work and recreational applications.
