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

Part Number: 883-02-155

Summary: The FOX Factory Race Series IFP Rear Bump Stops are engineered for 2007-2018 Jeep Wrangler JK owners seeking professional-grade bottom-out control. Utilizing technology derived from the Race Series, these bump stops provide increased damping performance during the final inches of suspension travel to eliminate harsh impacts. By separating oil and nitrogen, the system ensures consistent performance and prevents the bucking often associated with standard bump stops.

Features

• Internal Floating Piston (IFP): A specialized piston located in the shaft separates oil and nitrogen to provide increased damping performance and ensure cavitation-free operation.
• Threaded Body: The CNC machined 6061-T6 billet aluminum threaded body provides adjustable mounting heights to ensure precise engagement during suspension up-travel.
• Negative Coil Spring: An internal negative spring provides softened initial impacts to ensure a smooth transition and prevent harsh top-outs.
• FOX AIR VALVE (FAV): An integrated air valve located at the bottom of the shaft provides easy access for nitrogen pressure adjustments to ensure tunable bottom-out resistance.
• Delrin Strike Pad: A replaceable Delrin strike pad provides a durable contact surface to ensure quiet operation and longevity under repeated impacts.

Frequently Asked Questions

What is the benefit of the Internal Floating Piston (IFP) in these bump stops?
The IFP separates the oil from the nitrogen gas, which prevents cavitation and bucking, providing more consistent damping performance during the last few inches of travel.

Can the engagement point of these bump stops be adjusted?
Yes, the threaded body allows you to adjust the mounting height to fine-tune exactly when the bump stop engages during suspension up-travel.

Are the strike pads replaceable?
Yes, the bump stops feature a replaceable Delrin strike pad, which is protected and designed for long-term durability.
