FOX Factory PS Stabilizer IFP shock upgrade — Silver aluminium, CNC-machined precision

FOX Factory PS Stabilizer IFP 98524173 in silver is a high-performance internal floating piston (IFP) upgrade component engineered to separate oil from high-pressure nitrogen and improve shock response and durability.

Designed by FOX Factory — a long-standing leader in suspension engineering — the PS Stabilizer IFP is a precision-machined replacement part for compatible shocks. Its aluminum construction and CNC-anodized components are intended to maintain consistent damping characteristics under heavy use, whether in off-road trucks, ATVs, motorcycles, or high-performance recreational vehicles. This product is vehicle-specific, so fitment depends on your shock model and year.

How does the PS Stabilizer IFP affect shock performance?

Replacing or upgrading to the PS Stabilizer IFP helps preserve oil and gas separation inside the shock, reducing aeration and inconsistent damping. That stability translates to smoother, more predictable suspension behavior across repeated compression cycles.

• IFP separates oil from high-pressure nitrogen gas to prevent foaming
• Aluminum body improves thermal transfer and weight savings
• CNC-machined components ensure tight tolerances and consistent sealing

What are the build and materials of this IFP?

The unit uses a lightweight aluminum body combined with black anodized, CNC-machined aluminum parts for corrosion resistance and durability. Materials and finishes focus on longevity in harsh environments like off-road and heavy-duty workshops.

• Durable aluminum construction for strength and reduced mass
• Black anodized CNC-machined parts for precision and wear resistance
• Designed as a Performance Series smooth-body component

Will this fit my vehicle and how do I confirm compatibility?

This PS Stabilizer IFP is vehicle-specific; compatibility depends on your shock model, year, and internal configuration. Always confirm part number 98524173 against your shock assembly or consult FOX Factory fitment guides and the vehicle’s service manual before purchasing.

• Check FOX part number 98524173 for exact match
• Refer to your shock’s model and year for fitment verification
• Professional installation recommended for accurate sealing and preload settings

How should this IFP be installed and maintained?

Installation typically requires disassembly of the shock and careful handling of internal seals and fluids; follow manufacturer torque specs and cleanliness procedures. Regular inspection during shock service intervals helps maintain performance and prevents premature wear.

• Install during routine shock servicing or rebuilds
• Use proper nitrogen charging and oil fill procedures per FOX documentation
• Replace seals and check for corrosion or scoring when servicing

Who is this for: The FOX Factory PS Stabilizer IFP 98524173 is built for riders and vehicle owners who demand consistent, repeatable suspension performance—racers, off-road enthusiasts, professional mechanics, and anyone rebuilding or upgrading compatible FOX shocks. If you require reliable oil/gas separation, precise machining, and components designed for heavy-duty use, this IFP is intended as a direct-fit performance part when matched to the correct shock model.
