Product Description

The FOX98450327 is a FOX 2.0 Adventure Series IFP rear shock absorber custom-tuned by JKS specifically for the Jeep Wrangler JL and JLU platform with 2-3" of lift. Its monotube internal floating piston design completely isolates the shock oil from the nitrogen gas charge, preventing aeration and maintaining consistent, fade-free damping across all terrain. At 30.06" extended and 18.46" collapsed, this shock is correctly sized for the rear suspension travel of a JL or JLU at the 2-3" lift range - pairing precisely with JSPEC dual-rate coil springs for a balanced, well-controlled ride on and off road.

Built with a 2.0" seamless alloy body, thick silver powder coat, and a 5/8" chrome-plated heat-treated shaft, this shock handles the demands of lifted Jeep driving without compromise. Installation is a direct bolt-on using the factory EB1/EB1 rear mounting points and OEM hardware - no modification needed. It is a confirmed component of JKS JSPEC J-Venture, J-Kontrol, and J-Konnect "KFA"-suffix lift kits for the standard JL, JLU, diesel, and 4xe Wrangler variants. Sold individually - two units are required for a complete rear axle installation.
