FOX Factory Series Rear Bump Stops with IFP for 2018+ Jeep Wrangler JL, 1.853-Inch Travel, Pair - 883-02-168

Developed in racing and refined for everyday use, FOX Factory Race Series bumpstops are the perfect addition to any aggressive Jeep build, working together with your FOX shocks to create the feel of near bottomless travel. Application specific valving to maximize performance. Uncompromised performance through FOX’s patented internal bypass technology delivers the feel of near-endless suspension travel. Exclusive internal bypass technology allows oil to flow around the piston at some points of the stroke – while creating humongous pressure at other points – supporting the vehicle like no other product can. Floating through terrain is accomplished with FOX’s ride zone – combining a race-developed shock piston, internal bypass and Dual Speed Compression adjustment – allowing fine tuning for weight, terrain and speed. Dominate any terrain with the brute strength of 3- and 2.5-inch aluminum bodies, cactus cooler reservoirs and 7/8” shafts with redundant seals, all proven in the harshest of environments under the toughest of conditions.

• Performance Tuned For Vehicle Specific Application
• IFP Separates Oil From High-Pressure Nitrogen Gas
• Aluminum Body Dissipates Heat Faster Than Steel
• Black Anodized CNC Machined Aluminum Components
• Modifications Required

Developed through racing and refined for everyday driving, the FOX Factory Series rear bump stops are engineered for aggressive 2018 and newer Jeep Wrangler JL builds. Part number 883-02-168 uses application-specific valving to work with FOX suspension systems, helping control compression forces and maintain a composed feel when the vehicle reaches the end of its suspension travel. These bump stops are designed for demanding off-road use and may require vehicle modifications for installation.
FOX patented internal bypass technology allows oil to move around the piston during selected portions of the stroke, then generates increased pressure where additional support is needed. This progressive control helps protect the suspension from harsh bottoming while delivering a smoother, more controlled response over rough terrain. The integrated Internal Floating Piston (IFP) separates oil from high-pressure nitrogen gas to help maintain consistent damping performance and reduce aeration during extended use.
A ride-zone design combines race-developed piston technology, internal bypass control, and FOX suspension tuning principles to help optimize performance for vehicle weight, terrain, and speed. The aluminum body dissipates heat faster than steel, while black-anodized, CNC-machined aluminum components provide durable corrosion resistance and a clean, functional finish. Built for severe environments, the assembly includes robust construction intended to complement the strength and performance of FOX shocks.
