JKS JSPEC109KFP J-Kontrol 3.5 Inch Lift Kit with FOX 2.0 Performance Shocks

The JKS J-Kontrol 3.5" Lift Kit is a complete bolt-on suspension system designed to enhance both on-road handling and off-road capability. Building upon the proven J-Venture platform, the J-Kontrol system adds geometry-correcting components for superior driving dynamics while maintaining exceptional trail performance.

Key Components:

• Front and rear JSPEC dual-rate progressive coil springs for smooth ride quality across any terrain
• FOX 2.0 Performance Series gas shocks with custom valving optimized for this suspension system
• Front control arm correction brackets to restore factory geometry and improve caster angles
• HD drag link flip kit to flatten steering angles and eliminate bump steer
• Adjustable front track bar and rear track bar bracket for proper axle positioning
• Front sway bar Quicker Disconnects for enhanced articulation on the trail
• Front and rear bump stop extensions to maximize suspension travel safely
• Brake line relocation brackets for proper clearance
• All necessary hardware for complete bolt-on installation

Performance Benefits:

The control arm relocation brackets work to flatten the control arm angles, closely mimicking factory suspension geometry while correcting caster for improved handling characteristics. Combined with the drag link flip kit that optimizes steering angles, this system delivers exceptional on-road manners without sacrificing off-road capability. The JSPEC dual-rate coil springs provide a plush ride during highway cruising while offering progressive support as compression increases during heavy loading or aggressive trail use.

2012-2018 models with 3.6L Pentastar engines require exhaust modification for driveshaft clearance at full suspension droop (JKS8150 exhaust extensions recommended). Rubicon sway bar link hardware included. Requires 17-inch or larger wheels with 4.5-inch backspacing or less for proper steering clearance. Maximum recommended tire size is 35x12.50 on 16x8 wheels with 4.5-inch backspacing.
