3.5" 2020-2026 Jeep Wrangler JL Diesel / 392 (4 door) 4WD J-Venture Lift Kit by JKS

The JKS JSPEC158 J-Venture 3.5" suspension system for Diesel 4 Door Jeep Wrangler JL models increases ground clearance and tire clearance while delivering a balanced combination of off-road capability, on-road comfort, and low-maintenance performance. Engineered specifically to support the added weight and demands of the diesel platform, this suspension lift provides improved ride quality and predictable handling for both daily driving and trail use.

The J-Venture suspension system features dual-rate front and rear coil springs tuned for the diesel Wrangler JL to deliver a smooth, controlled ride on pavement with increased stability and control as suspension travel increases off-road. Designed as a matched system, these springs work in harmony with the rest of the suspension components to reduce body roll and maintain confident handling across varied terrain.

To maintain proper suspension geometry after lifting, the kit includes a JKS adjustable front track bar and rear track bar bracket to accurately recenter the axles. Front caster cam locks restore proper steering alignment and highway stability, while front sway bar Quicker Disconnects allow increased articulation during off-road use without sacrificing on-road control. Front and rear bump stop extensions and rear extended sway bar links are included to properly manage suspension travel and maintain correct sway bar geometry.

The J-Venture 3.5" suspension system is available with multiple FOX shock options to tailor performance and ride quality, 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. The result is a leveled stance, increased clearance, and a purpose-built suspension system that allows Diesel JL owners to explore confidently while maintaining comfort and control in everyday driving.
