Product Description

The FOX98450359 is a FOX 2.0 Adventure Series IFP rear shock absorber custom-tuned by JKS for the 2007-2018 Jeep Wrangler JK with 2.5-3.5" of lift. Its IFP monotube design completely isolates the shock oil from the nitrogen gas charge, preventing aeration and maintaining consistent, fade-free damping across all terrain. At 26.35" extended and 16.75" collapsed, this shock is correctly length-matched for the increased rear suspension travel of a lifted JK - working in direct tandem with JSPEC dual-rate coil springs to deliver a balanced, well-controlled ride both on and off road.

Built with a 2.0" seamless steel body, thick silver powder coat, and a robust 5/8" chrome-plated heat-treated shaft, this shock is built to handle the stresses of daily driving and aggressive trail use without compromise. The BP18/EB1 mounting configuration installs directly onto OEM JK rear shock mounting points using factory hardware - no modifications required. It is a confirmed component of all JKS JSPEC "KFA"-suffix lift kits for the JK platform including J-Venture, J-Kontrol, and J-Krawl systems, for both 2-Door and 4-Door Unlimited models including RHD variants. The matching front shock is FOX98450351, sold separately. Two units are required for a complete rear axle installation.
