Summary: The FOX Factory Race Series 2.0 Rear IFP Stop Bumps are engineered for the 2018-2024 Jeep Wrangler JL to provide professional-grade bottom-out control. Utilizing race-proven technology, these bump stops deliver increased damping performance in the final inches of suspension travel. The Internal Floating Piston (IFP) and threaded aluminum body allow for precise tuning and consistent performance during high-speed off-road operation.

Features

• Internal Floating Piston (IFP): An IFP located in the shaft separates the oil and nitrogen to prevent cavitation and bucking to ensure consistent 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 provides softened initial impacts to ensure the mitigation of harsh top-outs.
• FOX AIR VALVE (FAV): An integrated valve located at the bottom of the shaft provides easy access for nitrogen pressure adjustments to ensure tunable bottom-out resistance.
• Replaceable Strike Pad: A durable Delrin® strike pad provides a sacrificial contact point to ensure protection of the bump stop components.

Frequently Asked Questions

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

Can I adjust when the bump stop engages?
Yes, the threaded aluminum body allows you to adjust the mounting height, which fine-tunes exactly when the bump stop engages during the suspension’s up-travel.

Are these bump stops compatible with stock height Jeeps?
No, these specific stop bumps are designed for 2018-2024 Jeep Wrangler JL models with 2.5 inches of lift or more.
