JKS FOX98450828 FOX 2.0 Adventure Rear Shock 31.05in Universal

Vehicle Fitment

• Universal shock absorber; vehicle-specific fitment requires matching mounting dimensions, travel and suspension lift height.

Fitment Notes

• FOX98450828 is a FOX 2.0 Adventure Series shock sold by JKS Manufacturing/Zone Offroad.
• This component is used as a rear shock in documented Zone Offroad lift-system applications.
• Do not assign vehicle-specific fitment from the shock dimensions alone; verify the complete suspension configuration before installation.
• Documented Ford F-150 applications include lift-kit configurations using this shock on 2009-2024 F-150 4WD models.
• Documented 2021-2024 F-150 applications use the shock with approximately 3-4 inches of lift in applicable Zone Offroad configurations.
• Documented earlier F-150 configurations use the shock with approximately 2-3 inches of lift in applicable Zone Offroad configurations.
• Mounting orientation and compatibility must be confirmed against the specific lift kit and vehicle suspension geometry.

Features

• FOX 2.0 Adventure Series monotube shock absorber.
• Internal floating piston (IFP) design separates shock oil from pressurized nitrogen.
• Helps reduce oil aeration during repeated off-road suspension cycling.
• 2.0-inch smooth-bore, honed seamless alloy-steel body.
• Thick protective silver powder-coated body finish.
• 5/8-inch hard-chrome-plated, heat-treated alloy-steel shaft.
• Quiet nitrile rubber bushings support suspension articulation.
• Uses JM92 Advanced Suspension Fluid for temperature-stable damping performance.
• Non-adjustable damping configuration.
• Designed for on-road ride comfort and predictable off-road handling.
• Direct-replacement mounting design for compatible stock and lifted suspension systems.
• Application-specific valving is used to complement compatible suspension lift configurations.

Product Description

The JKS FOX98450828 is a FOX 2.0 Adventure Series monotube shock absorber designed to provide controlled suspension damping for compatible lifted truck and off-road applications. Its internal floating piston separates the shock oil from the high-pressure nitrogen chamber, helping reduce oil aeration and maintain consistent damping during repeated suspension movement.

The shock features a 2.0-inch smooth-bore alloy-steel body, protective powder coating, a 5/8-inch hard-chrome-plated heat-treated alloy-steel shaft and quiet nitrile rubber bushings. FOX's JM92 Advanced Suspension Fluid is used to maintain damping performance across varying operating temperatures, while the non-adjustable valving is configured for predictable on-road and off-road performance.

FOX98450828 measures 31.05 inches extended and 18.96 inches compressed, providing 12.09 inches of travel. It is supplied as one shock with mounting bushings. Although this shock is documented in several Zone Offroad Ford F-150 lift systems, it should not be treated as universally vehicle-specific; installation requires confirmation of mounting style, suspension travel and lift height for the exact vehicle and suspension configuration.
