4.5" 2018-2026 Jeep Wrangler JL (4 Door) J-Konnect Lift Kit by JKS

The JKS J-Konnect 4.5" suspension lift kit for Jeep Wrangler JL models delivers serious off-road capability with the clearance, strength, and suspension geometry required for aggressive terrain while maintaining controlled on-road manners. Designed as a complete bolt-on suspension system, this 4.5-inch lift provides clearance for up to 37-inch tires, increased suspension travel, and an aggressive stance suitable for both trail-focused builds and daily-driven Jeeps. The system is compatible with both 2-door and 4-door JL platforms.

At the core of the J-Konnect system are heavy-duty fixed-length lower J-Link control arms engineered to improve axle geometry and overall durability after lifting. These control arms are available with either factory-style rubber bushings to reduce noise, vibration, and harshness, or JKS Flex Ends for increased articulation and trail-focused performance. Spring options include standard-rate or heavy-duty dual-rate coil springs, allowing the suspension to be tuned for vehicle weight, accessories, and intended use. JKS dual-rate coil springs are specifically tuned for the JL platform to deliver a smooth, controlled ride on pavement while transitioning to increased stability and flex off-road.

To maintain proper suspension geometry and component alignment, the system includes front and rear track bar brackets, control arm correction brackets, extended sway bar links with front Quicker Disconnects, front and rear bump stop extensions, and brake line relocation brackets. Each component is engineered for bolt-on installation using factory mounting points, ensuring predictable handling, proper axle positioning, and long-term reliability at increased ride height.

The J-Konnect 4.5" suspension system is available with multiple FOX shock options to tailor damping performance and ride quality to specific driving styles and terrain demands. Shock options include FOX 2.0 Adventure Series, FOX 2.0 Performance Series, FOX 2.5 Performance Elite Series, and FOX 3.0 Factory Race Series shocks. With configurable shock options, spring rates, and control arm bushing styles, this suspension system provides a versatile, upgrade-ready foundation for Jeep Wrangler JL owners seeking confident trail performance and refined on-road control.
