4" 2007-2018 Jeep Wrangler JK 4WD Coil Spring Lift Kit (w/Bilstein 5100 Shocks) by ReadyLift

The ReadyLIFT 69-6404 4" Lift Kit is a complete suspension solution designed for 2007–2018 Jeep Wrangler JK 2-door and 4-door models. Engineered for both on-road comfort and off-road capability, this system delivers a balanced lift, improved handling, and the clearance needed for larger tires.

This kit features four precision-crafted coil springs that provide approximately 4" of front lift and 3" of rear lift, resulting in a level, aggressive stance. Designed to maintain factory-like ride quality, these springs offer excellent road manners while increasing suspension articulation for off-road performance.

To ensure proper suspension geometry after lifting, the kit includes front caster correction brackets and an adjustable front track bar to properly center the axle. A rear heavy-duty track bar relocation bracket is also included to maintain correct rear axle positioning.

Ride quality and damping are handled by a full set of Bilstein 5100 Series shocks, known for their monotube design and digressive valving, delivering improved control both on-road and over rough terrain.

Additional components such as sway bar end links, bump stop extensions, and all necessary hardware ensure proper suspension function throughout the full range of travel. For 2012–2018 models, front exhaust spacers are included to maintain proper clearance during suspension articulation.

This complete kit allows you to confidently upgrade your JK with improved ground clearance, enhanced capability, and the ability to run up to 35" tires (or 37" tires with flat fenders) without sacrificing ride quality.
