The FOX 3.0 Factory Bypass shock is listed for JKS J-Krawl 3.5" 4-door Jeep Wrangler JL applications (2020-2021) where the kit calls for enhanced damping. As a 3.0 Factory bypass unit it is intended to work with J-Krawl’s high-articulation geometry, dual-rate springs and upgraded control arms to provide controlled compression and rebound through heavy off-road use and extended suspension travel scenarios when the application specifies factory bypass hardware.
