JKS J-Kontrol 3.5" Suspension Lift with Fox 2.0 Adventure Series Shocks for Jeep Wrangler JL 4-Door 2018-2025

Fits select 2018-2025 Jeep Wrangler JL 4-Door models including Unlimited Rubicon, Sahara, Sport, Willys, and High Altitude.

The JKS J-Kontrol 3.5" suspension system is engineered for Jeep owners who demand a balance between daily-driver stability and technical trail capability. Building on the J-Venture platform, the J-Kontrol system adds front control arm correction brackets. These brackets relocate the frame-side mounting points to flatten the upper and lower control arm angles, restoring factory-style geometry and correcting caster for significantly improved steering feel and reduced brake dive.

Damping is handled by Fox 2.0 Adventure Series gas shocks, specifically valved for this suspension system. Combined with JKS heavy-duty dual-rate coil springs, this kit provides a predictable, compliant ride on pavement while maintaining the travel and bottom-out resistance required for off-road obstacles. To ensure proper axle alignment, the kit includes a front adjustable track bar and a rear track bar relocation bracket.

• Fox 2.0 Adventure Series Shocks: Custom-valved gas shocks for superior damping performance on diverse terrain.
• HD Dual Rate Coil Springs: Designed for excellent ride quality and consistent handling under load.
• Control Arm Correction Brackets: Flattens control arm angles to correct caster and optimize suspension geometry.
• Front Adjustable Track Bar: Forged track bar allows for precise centering of the front axle.
• Quicker Disconnects: Front sway bar disconnects and rear links provide increased off-road articulation.
• Bump Stop Extensions: Front and rear extensions properly limit up-travel to protect suspension components.
