3.5" 2018-2026 Jeep Wrangler JL (4 door) 4WD J-Venture Lift Kit by JKS

The JKS JSPEC119 J-Venture 3.5" suspension system for Jeep Wrangler JL 4-Door models increases ground clearance, tire clearance, and overall performance while maintaining a comfortable, low-maintenance driving experience. Designed as a complete bolt-on suspension lift kit, this entry-level performance system delivers a balanced combination of on-road comfort and off-road capability for daily-driven Jeeps that see regular trail use.

This suspension system features matched JSPEC dual-rate coil springs engineered using JKS J-Rated progressive spring technology to deliver a smooth, controlled ride during light-load driving while increasing spring rate as suspension compression rises. Available in standard or heavy-duty configurations, the coil springs provide predictable handling on pavement and improved control when navigating uneven or demanding terrain.

To maintain proper suspension geometry after lifting, the J-Venture kit includes a front adjustable track bar and rear track bar bracket to properly recenter the axles, along with front caster cam locks to restore correct steering feel and highway stability. Front sway bar Quicker Disconnects increase articulation during off-road driving, while extended rear sway bar links and front and rear bump stop extensions ensure correct component operation and controlled suspension travel.

The J-Venture 3.5" suspension system is available with multiple FOX shock options to tailor ride quality and performance, including FOX 2.0 Adventure Series, FOX 2.0 Performance Series, FOX 2.5 IFP Performance Series, and FOX 2.5 Performance Elite Series shocks. Tuned as a complete system by JKS engineers, this suspension delivers a refined driving experience on-road while providing the confidence and control needed to explore more demanding trails.
