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

JSPEC154KFA JKS J-Lander 3.5" Suspension System for 2007–2018 Jeep Wrangler JK 4-Door models is engineered to create a capable, load-ready overland build without sacrificing daily drivability. Designed for adventure-focused JK owners, this complete bolt-on system increases ground clearance, improves ride quality under added gear weight, and delivers the balanced performance needed for long-distance travel and off-grid exploration.

The J-Lander system combines front and rear JSPEC dual-rate coil springs with rear ACOS adjustable coil spacers, allowing ride height to be fine-tuned based on cargo, bumpers, roof racks, and overland equipment. The front receives 3.5" dual-rate coils, while the rear utilizes 2.5" coils paired with ACOS spacers to dial in stance and load compensation. This configuration provides a comfortable on-road ride while maintaining stability and control when fully loaded.

Shock options include FOX 2.0 Adventure Series, FOX 2.0 Performance Series, and FOX 2.5 Performance Elite Series, each custom-valved to complement the J-Lander spring rates and designed for overland use. These premium monotube gas shocks deliver controlled damping, improved heat management, and confident performance across washboard roads, rocky trails, and highway miles alike.

Additional components include a front adjustable track bar and rear track bar bracket to properly recenter the axles after lifting, front sway bar, Quicker Disconnects for increased articulation off-road, front and rear lower J-Link control arms for added strength and caster correction, and bump stop extensions to properly manage suspension travel. Purpose-built for reliability, adjustability, and low maintenance, the J-Lander 3.5" Suspension System is ready to take your JK further—wherever the road ends.
