Upgrade your Jeep Wrangler JL with the JKS J-Konnect 4.5” Suspension Lift Kit, engineered to deliver serious off-road performance without sacrificing on-road comfort. This complete system provides enough lift to clear up to 37” tires, giving your JL a more aggressive stance and increased ground clearance. At the heart of the kit are heavy-duty fixed-length lower J-Flex control arms with factory-style rubber bushings or JKS Joints. These arms are designed to improve axle geometry and enhance overall durability. JKS's Dual-rate coil springs, specifically tuned for the JL platform, ensure a smooth ride on the pavement while allowing maximum flex on the trail.

To keep your suspension properly aligned and functioning, the kit includes front and rear track bar brackets, extended sway bar links, bump stop extensions, and brake line relocation brackets. Everything is engineered for bolt-on installation and long-term reliability. Whether you're hitting hardcore trails or commuting daily, the J-Konnect system delivers the perfect balance of control, comfort, and clearance. Compatible with both 2-door and 4-door JL models, and upgrade-ready for those looking to fine-tune their build further, this kit is the ideal foundation for any serious Jeep Wrangler build. Choose JKS for proven performance, trusted quality, and trail-tested design that takes your Jeep to the next level.
