FOX Performance Series Front Shock 2017-2025 Ford F-250/350 Super Duty 5..5–7″ Lift
2017–2025 Ford F-250/F-350 Super Duty 4WD Front Fox Performance Series 2.0 IFP Shock (5.5–7” Lift)
Upgrade your ride quality and off-road performance with the Fox Performance Series 2.0 IFP smooth body shock, engineered to deliver the latest in shock technology for your truck or SUV. Utilizing race-proven damping control, this shock provides 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 will never rust, ensuring long-term durability. Inside, FOX’s race-proven performance valving technology works alongside an Internal Floating Piston (IFP) mono-tube design that separates shock oil from the high-pressure nitrogen gas chamber. This design eliminates oil aeration, allowing the shock to maintain consistent damping performance. A race-developed high-flow damping piston paired with application-specific valving delivers a smooth, controlled, and predictable ride quality capable of handling rough terrain with confidence.

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.
