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

JSPEC108KFA JKS J-Kontrol 3.5" Suspension System is engineered specifically for 2007–2018 Jeep Wrangler JK 4-Door models, delivering improved ground clearance, corrected suspension geometry, and enhanced on-road and off-road stability. Designed as a performance-focused step up from the J-Venture system, J-Kontrol adds key geometry-correcting components to provide better steering feel, improved caster, and more predictable handling after lifting. This true bolt-on system is ideal for drivers who want aggressive trail capability without sacrificing daily drivability.

At the core of the system are front and rear JSPEC dual-rate coil springs that provide a comfortable ride on pavement while transitioning to a firmer rate under load or during off-road articulation. Front control arm relocation brackets flatten the control arm angles and restore proper caster, improving tracking and steering response. The included HD drag link flip kit with integrated track bar bracket corrects steering geometry, reducing bump steer and maintaining factory-like steering angles even at increased ride height.

J-Kontrol offers a choice of custom-valved FOX shock options, including FOX 2.0 Adventure Series, FOX 2.0 Performance Series, FOX 2.0 Remote Reservoir, and FOX 2.5 Performance Elite shocks. Each option is tuned to complement the spring rates and overall system design for balanced compression and rebound control across varying terrain. A front-adjustable track bar and a rear track bar bracket properly recenter the axles, while Quicker Disconnect sway bar links increase articulation when the trail demands it. Front and rear bump stop extensions protect suspension components at full compression, making this system a well-rounded upgrade for JK owners seeking control, clearance, and confidence on and off the road.
