Fox 2.0 Factory Race Series IFP Bump Stops

Part Number: 2×983-02-171

Summary: The FOX Factory Race Series IFP bump stops are engineered to provide increased damping performance and bottom-out control during the final inches of suspension travel. Utilizing an Internal Floating Piston (IFP) located in the shaft, these units effectively separate oil and nitrogen to prevent cavitation and “bucking” during aggressive off-road use. The threaded body construction allows for precise mounting height adjustments to fine-tune engagement, ensuring you can utilize the full range of your suspension without the shock of a harsh bottom-out.

Features

• Internal Floating Piston (IFP): An IFP located in the shaft provides separation of oil and nitrogen to ensure consistent damping performance and prevent cavitation.
• Threaded Body: Impact extruded, black anodized 6061-T6 billet aluminum provides adjustable mounting height to ensure precise control over bump stop engagement.
• Negative Coil Spring: An internal negative spring provides softened initial impacts to ensure a reduction in harsh top-outs.
• FOX AIR VALVE (FAV): An integrated valve located at the bottom of the shaft provides easy access to nitrogen pressure adjustments to ensure the system is tuned to specific vehicle needs.
• Replaceable Delrin® Strike Pad: A durable strike pad provides a sacrificial contact point to ensure protection for the bump stop shaft and internal components.

• Performance Benefit: Drivers experience a significant reduction in harsh bottom-out forces, allowing for more confident operation across rough terrain.

Frequently Asked Questions

What is the purpose of the Internal Floating Piston (IFP) in this bump stop?
The IFP separates the oil and nitrogen charges within the shaft to prevent cavitation and bucking, providing more consistent damping during impacts.

Can I adjust when the bump stop engages?
Yes, the threaded body allows you to adjust the mounting height to fine-tune exactly when the bump stop contacts the strike surface during suspension up-travel.

Is the strike pad replaceable?
Yes, the unit features a replaceable Delrin® strike pad designed to protect the shaft and absorb impact energy.
