FOX 2.0 Performance Series Rear Shock for 2017–2025 Ford F-250/350 4WD 0–1″ Lift
2017–2025 Ford F-250/F-350 Super Duty 4WD Rear Fox 2.0 Performance Series IFP Shock (0–1" Lift)
Upgrade your suspension with the proven performance of FOX. The FOX 2.0 Performance Series IFP Shock features the latest in shock technology to transform the performance of your truck or SUV. Engineered with race-proven damping control, it delivers a comfortable on-road ride while maintaining predictable handling in even the toughest off-road conditions. The precision metal impact aluminum body increases cooling capacity and resists corrosion, while the internal floating piston (IFP) mono-tube design separates shock oil from high-pressure nitrogen to eliminate aeration. Combined with high-flow damping pistons and application-specific valving, this shock provides consistent, controlled performance across all terrains.

Why Fox Shocks
Fox shocks are well-regarded in the off-road and performance world because they combine durability, advanced damping technology, and customization options that suit a wide range of vehicles and driving styles. For 4WD trucks, the “best” Fox shocks depend on how you actually use the truck — daily driving, towing, trail riding, or hardcore off-road.
Fox Shocks FAQ's
Should I Get 2.0 or 2.5 Shocks
Choose Fox 2.0 if:
You prioritize a smoother daily ride.
You stick to moderate trails and lighter off-road use.
Budget-friendly performance is key.
Choose Fox 2.5 if:
You demand more from your suspension—like aggressive off-roading, towing, or extended high-speed use.
You need better heat management and durability.
You don’t mind paying a bit more for enhanced performance and longevity.
Why Monotube Shocks Excel on Lifted Trucks
Handles Added Unsprung Weight – Larger wheels/tires from a lift add rotational mass and stress to your suspension. Monotube designs have better damping control to keep those tires planted.
Better Heat Dissipation – The single-tube design allows oil and gas to cool more efficiently, preventing fade during towing, off-roading, or long highway runs.
More Precise Handling – They respond faster to suspension movement, which is critical when correcting for body roll in a taller truck.
Will Better Shocks Improve Ride Quality
Tightening Up a Floaty Vehicle
If your truck feels like it’s “floating” or wandering at highway speeds, new shocks will firm up the suspension, improve steering response, and keep the body from rolling excessively in turns.
This doesn’t necessarily make the ride softer — it makes it more controlled.
Reducing Harsh Bouncing & Jarring
If you’re feeling hard bounce after hitting a bump (especially front or rear “pogo stick” motion), your shocks likely have lost rebound damping.
New shocks restore that damping, keeping your tires on the ground and absorbing energy before it reaches you.
Why Measure Shocks and Lift Height
1. Improved Ride Comfort
Matching the right shocks to your truck’s lift height enhances ride comfort. Ill-fitting shocks can cause a harsh, bumpy ride and limit suspension travel.
2. Better Handling & Control
Shocks sized for your lift height improve steering stability, cornering, and overall control — especially on rough terrain or with larger tires.
3. Increased Safety
The right shocks keep your tires in consistent contact with the ground, reducing the risk of skids, loss of control, or suspension component damage.
4. Greater Durability
When shocks operate within their intended range, they last longer and protect other suspension parts from premature wear.
5. Optimal Performance
A well-matched suspension setup ensures your truck performs at its best, whether you’re off-roading, towing, hauling, or commuting daily.
