Rough Country N3 Rear Shocks for 2017–24 Ford Super Duty 0–4.5" Lift — Nitrogen-Charged, 54mm Body

Rough Country N3 rear shocks (23190_A) are heavy-duty, nitrogen-charged rear dampers engineered to improve ride control and durability for 2017–2024 Ford Super Duty trucks with 0–4.5" lift.

These rear shocks combine a robust 54mm body, multi-stage valving and cold-rated hydraulic fluid to manage the weight and towing demands of Super Duty platforms. Designed for trucks lifted up to 4.5 inches, the N3 rear units deliver firmer damping under load while still allowing compliant wheel motion on moderate road irregularities. Built with materials and seals intended for long service life, they come backed by Rough Country’s limited lifetime replacement warranty for added peace of mind.

How do these shocks change towing and hauling stability?

When carrying heavy loads or towing, these shocks reduce excessive squat and improve axle control so the truck tracks more predictably. The 10-stage variable valving adjusts damping across a range of speeds, helping maintain tire contact and reduce trailer sway inputs.

• 10-stage variable valving for progressive control
• Nitrogen charge to reduce aeration under sustained use
• 54mm fast-cooling shock body to dissipate heat from heavy work

Will they handle cold-weather use and off-road duty?

These shocks use military-grade hydraulic fluid rated for very low temperatures, keeping damping consistent in cold climates. Rubber bushings and a spring-loaded piston rod seal are included to resist contaminants encountered off-road, extending service life in rough conditions.

• Military-spec fluid rated for extremely low temperatures
• Durable rubber bushings to isolate noise and vibration
• Spring-loaded piston rod seal for enhanced contamination protection

What makes the build quality stand out compared with stock shocks?

Rough Country engineered the N3 rear shocks with higher-strength components and a tensile-rated construction to withstand the heavier loads common to Super Duty use. The larger 54mm body and nitrogen charge help maintain consistent performance under repeated stress, while military-rated fluid preserves damping characteristics across a wide temperature range.

• 36 kN tensile strength components for rugged reliability
• Nitrogen-charged design to minimize fade and cavitation
• Fast-cooling body for sustained heavy-duty operation

How easy is installation and what does the warranty cover?

These shocks are direct-fit replacement units for 2017–2024 Ford Super Duty trucks with 0–4.5" lift, requiring no custom modifications for most standard installs. Rough Country stands behind the product with a limited lifetime replacement warranty, which covers manufacturing defects under normal use—refer to the warranty terms for full details.

• Direct-fit for specified model years and lift ranges
• Limited lifetime replacement warranty included
• Installation uses factory mounting points for straightforward swap

Who is this for? These Rough Country N3 rear shocks are aimed at Ford Super Duty owners who tow, haul or drive off-road and need stiffer, more heat-resistant rear damping than factory shocks provide. They suit drivers running mild to moderate lifts up to 4.5 inches who want improved load control, reduced shock fade under sustained towing, and components built for rugged use. If you prioritize consistent handling under load and durability in varied climates, these shocks are engineered for that purpose.
