• Delta Joint UCA: Billet 6061 aluminum arms with a patented Delta Joint provide high-angle articulation and weather resistance to ensure long-term reliability and improved suspension geometry.
• Billet Lower Links: CNC machined 6061 aluminum trailing arms provide superior strength and on-vehicle pinion angle adjustment to ensure optimized drivetrain geometry.
• Remote Reservoir Shocks: 2.5 Aluminum Series rear shocks with 7/8 inches shafts provide increased heat dissipation to ensure fade-free performance in demanding terrain.
• Air-to-Coil Conversion: A vehicle-specific conversion kit provides a reliable mechanical spring setup to ensure the elimination of factory air bag failures.
• System Durability: FK Rod End bearings and CAD plated shock bodies provide minimal deflection and corrosion resistance to ensure maximum component longevity.
• Installation: A 100% Bolt-on design provides a straightforward upgrade path to ensure no cutting or welding is required for fitment.
