3.5" 2020-2026 Jeep Wrangler JL Diesel / 392 (4 Door) J-Konnect Lift Kit by JKS

The JKS J-Konnect 3.5" suspension system for Diesel Jeep Wrangler JL 4-Door models increases ground clearance, supports larger tires, and delivers significantly improved off-road capability while maintaining excellent on-road manners. Designed as a bolt-on performance suspension, this system is engineered specifically to handle the added weight and demands of the diesel platform while providing a balanced upgrade for trail use and daily driving.

Positioned as a strength-focused step up from the JKS J-Venture lineup, the J-Konnect system replaces factory lower control arms with front and rear fixed-length J-Link lower control arms. These control arms add front caster and rear wheelbase while offering a substantial strength upgrade over OE components. Constructed from 2" x .250-wall DOM tubing and equipped with large factory-style rubber bushings, the J-Link control arms improve durability while maintaining street-friendly noise, vibration, and harshness characteristics.

Matched dual-rate front and rear coil springs are tuned to deliver smooth ride quality during daily driving while increasing stability and control as suspension travel increases off-road. An adjustable front track bar and rear track bar bracket are included to properly recenter the axles after lifting, while front sway bar Quicker Disconnects and rear sway bar links increase articulation when navigating uneven terrain. Front and rear bump stop extensions are included to properly manage suspension travel and protect critical components.

The J-Konnect 3.5" suspension system is available with multiple FOX shock options to tailor ride quality and performance to specific driving styles and terrain demands. Shock options include FOX 2.0 Adventure Series, FOX 2.0 Performance Series, FOX 2.5 Performance Series, and FOX 2.5 Performance Elite Series shocks. Tuned as a complete system, this suspension delivers aggressive off-road performance and strength while preserving the refined handling and drivability expected from a well-engineered diesel JL suspension upgrade.
