Rough Country N3 Rear Shocks for 1999–2016 Ford Super Duty 0–2" Lift — 10-Stage Valving, 54mm Body

Rough Country 0–2" N3 Rear Shocks (23210_D) are heavy-duty replacement shocks tuned for 1999–2016 Ford Super Duty trucks to restore ride control and handle towing or light off-road use.

These rear shocks are engineered as a direct-fit upgrade for Super Duty models built between 1999 and 2016. They combine multistage valving, a thick shock body and military-grade damping fluid to deliver consistent performance in cold temperatures and under load. Designed for trucks that run stock height up to a 2" lift, these shocks prioritize durability, heat management and long-term service backed by Rough Country’s limited lifetime replacement warranty.

How do these shocks improve driving feel on a loaded Super Duty?

The N3 valving is set up to manage the dynamic loads of towing, hauling and uneven terrain, reducing excess body roll and bottoming during compression. You’ll notice firmer control through corners and when braking while carrying heavy payloads.

• 10-stage variable valving for progressive damping response
• 54mm fast-cooling shock body to dissipate heat under continuous use
• Nitrogen-charged design reduces aeration for consistent feel
• Spring-loaded piston rod seal helps maintain seal integrity under stress

Will these shocks survive cold weather and harsh conditions?

Yes—these shocks use a military-grade damping fluid rated to operate reliably at extreme low temperatures, ensuring consistent damping when ambient conditions drop. Robust seals and corrosion-resistant components also help them hold up in wet or salty environments.

• Military fluid performance down to -50°C for stable cold-start damping
• Rubber bushings for vibration isolation and environmental resistance
• Durable construction designed for frequent temperature cycling

What build features deliver long-term reliability?

Rough Country engineered these shocks with a focus on longevity: high-strength hardware, a thick 54mm body for heat warpage resistance, and heavy-duty internal components to resist wear under heavy loads. The company supports the product with a limited lifetime replacement warranty for added peace of mind.

• 36 kN tensile-strength components for tough mechanical durability
• Rubber-mounted ends reduce bushing wear and noise transmission
• Backed by Rough Country’s limited lifetime replacement warranty

Are these shocks the right fit for a lifted or stock-height truck?

These N3 rear shocks are specified for 0–2" of lift; they work as replacements for stock-height trucks up through mild lifts. Confirm fitment against your specific model year and rear axle configuration before purchase to ensure proper ride height and travel.

• Designed to fit 1999–2016 Ford Super Duty rear applications
• Engineered for 0–2" lift ranges—suitable for stock or mild-lift setups
• Direct-replacement mounting for simple installation

Who is this for: These shocks are aimed at Super Duty owners who tow, haul or use their trucks off the pavement occasionally and want a durable, temperature-resistant rear damping upgrade without changing vehicle geometry. If you need reliable shock control for work duty, weekend trails, or improving rear stability under load and want a direct-fit, warranty-supported solution, the Rough Country 0–2" N3 Rear Shocks (23210_D) are a practical choice.
