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

Part Number: 883-02-154_883-02-155

Summary: The FOX Factory Race Series bump stop system is engineered to provide increased damping performance and bottom-out control for the 2007-2018 Jeep Wrangler JK. Utilizing race-derived technology, these units manage the final inches of suspension travel to prevent harsh impacts during off-road operation. The design features a threaded aluminum body and an Internal Floating Piston (IFP) to ensure consistent performance under demanding conditions.

Features

• Internal Floating Piston (IFP): An Internal Floating Piston (IFP) in the shaft separates the oil and nitrogen to prevent cavitation and bucking to ensure increased damping performance.
• Threaded Body: Impact extruded, black anodized 6061-T6 billet aluminum construction provides adjustable mounting height to ensure fine-tuned engagement during suspension up-travel.
• Negative Coil Spring: An internal spring mechanism softens initial impacts to ensure protection against harsh top-outs.
• Replaceable Delrin® Strike Pad: A durable strike pad protects the FOX AIR VALVE (FAV) to ensure long-term serviceability and easy access for nitrogen pressure adjustments.

Frequently Asked Questions

Are these bump stops adjustable?
Yes, the threaded body allows for mounting height adjustments to control engagement, and the nitrogen pressure can be tuned via the integrated FOX AIR VALVE.

What is the benefit of the IFP in these bump stops?
The Internal Floating Piston (IFP) separates the oil from the nitrogen gas, which prevents cavitation and ensures consistent damping during rapid suspension movements.

Can the strike pads be replaced?
Yes, these units feature replaceable Delrin strike pads which protect the internal components and the air valve from impact damage.
