3.5" 2007-2018 Jeep Wrangler JK (4 Door) J-Konnect Lift Kit by JKS

JSPEC113KFA JKS J-Konnect 3.5" Suspension Lift Kit is engineered for 2007–2018 Jeep Wrangler JK 4-Door models seeking increased ground clearance, improved suspension geometry, and serious off-road capability. Designed as a performance-driven upgrade over the J-Venture platform, the J-Konnect system adds reinforced components and steering correction to create a balanced suspension solution that performs confidently on rugged trails while maintaining composed on-road manners.

At the core of the system are front and rear JSPEC dual-rate coil springs paired with your choice of FOX shock options, including 2.0 Adventure Series, 2.0 Performance Series, 2.0 Remote Reservoir, and 2.5 Performance Elite. Each shock option is specifically valved to complement the spring rates and overall suspension geometry, delivering controlled damping, improved stability, and consistent performance whether navigating highway miles or technical terrain.

Strength and geometry correction are enhanced through front and rear fixed-length J-Link lower control arms constructed from 2" x .250-wall DOM tubing. These heavy-duty arms improve front caster and rear wheelbase while retaining factory-style rubber bushings to maintain controlled NVH characteristics. A heavy-duty drag link flip kit with integrated track bar bracket flattens steering angles for improved handling and reduced bump steer, while front and rear track bar support braces add reinforcement and protection.

Rounding out the system are a front-adjustable track bar, rear track bar bracket, front sway bar Quicker Disconnects, and front and rear bump stop extensions to properly recenter the axles, maximize articulation, and protect suspension components. The result is a complete 3.5-inch lift system that delivers aggressive trail performance, improved steering geometry, and reliable daily drivability in one cohesive package.
