Fox Factory Race Series IFP 2.0 Front Bump Stops for 2007-2018 Jeep Wrangler JK 2WD/4WD

Part Number: 883-02-154

Summary: The FOX Factory Race Series IFP 2.0 Front Bump Stops are engineered to provide professional-grade bottom-out control for the 2007-2018 Jeep Wrangler JK. Drawing from Race Series technology, these bump stops utilize an Internal Floating Piston (IFP) to deliver increased damping performance in the final inches of suspension travel. Designed to eliminate harsh impacts, this system ensures you can utilize the full range of your suspension without the risk of bottoming out during high-speed or off-road operation.

Features

• Internal Floating Piston (IFP): A specialized piston located in the shaft separates oil and nitrogen to prevent cavitation and bucking to ensure consistent damping performance.
• Threaded Body: Impact extruded 6061-T6 billet aluminum construction provides adjustable mounting height to ensure precise fine-tuning of bump stop engagement.
• Negative Coil Spring: An internal spring mechanism softens initial impacts to ensure a reduction in harsh top outs.
• Replaceable Delrin® Strike Pad: A durable, high-density strike pad provides a sacrificial contact point to ensure protection of the bump stop assembly.
• FOX AIR VALVE (FAV): An integrated valve located at the bottom of the shaft provides easy access to ensure nitrogen pressure adjustments are simple.

Frequently Asked Questions

What is the purpose of the Internal Floating Piston (IFP) in these bump stops?
The IFP separates the oil and nitrogen within the shaft to prevent cavitation and bucking, which provides more consistent damping performance during suspension travel.

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 engages during up travel.

Are the strike pads replaceable?
Yes, these bump stops feature replaceable Delrin strike pads to protect the unit and maintain smooth engagement over time.
