Rough Country Super Duty 4WD N3 Front Shocks (2005-2026)

Rough Country's N3 front shocks bring a significant step up in damping performance for 2005-2026 4WD F-250 and F-350 Super Duty trucks. Built around a 54mm shock body and a high-pressure nitrogen charge, these shocks deliver controlled, consistent response whether you're loaded down on the highway or navigating rough terrain. Available in four lift fitments, 0-1.5 inch, 2-4 inch, 4.5 inch, and 5-7 inch, they slot into your existing suspension setup without extensive modification.

10-stage variable valving. The multi-stage valving adjusts damping force across the full range of shock travel, providing a composed highway ride and confident control when the terrain gets unpredictable. Paired with a 35mm high-performance piston, the valving handles both light undulations and hard impacts without the wallowing or harshness common in stock Super Duty dampers.

Built for durability in demanding conditions. The 18mm chromed hardened piston rod resists corrosion and surface wear from mud, debris, and water intrusion. A spring-loaded piston rod seal maintains a tight barrier against leaks over the life of the shock, and the nitrogen charge prevents cavitation-related fade during sustained off-road use or repeated hard hits. Tensile strength is rated at 36kN to handle heavy loads and extreme impacts without structural compromise.

All-weather reliability and thermal management. Military-spec fluid rated to -40 degrees Celsius keeps damping consistent in extreme cold, while the 54mm shock body surface area accelerates heat dissipation to prevent performance fade during intense use. Natural rubber bushings round out the package, absorbing vibration and reducing road noise for a quieter cabin. The metallic silver paint finish adds a layer of corrosion resistance to the exterior body.
