JKS JSPEC108KFP J-Kontrol 3.5" Lift Kit for Jeep Wrangler JK 4-Door

The JKS J-Kontrol 3.5" suspension lift kit is a complete bolt-on system designed to increase ground clearance and enhance both on-road handling and off-road performance for 2007-2018 Jeep Wrangler JK 4-Door models. This premium system represents a significant upgrade from the J-Venture series by incorporating geometry-correcting components that restore factory-like handling characteristics while providing the lift needed for larger tires and improved trail capability.

Key Features:

• JSPEC dual-rate progressive coil springs (front and rear) for smooth highway cruising with increased load capacity under compression
• Choice of FOX shock options specifically valved for this system (Adventure Series, 2.0 Performance Series, or 2.5 Elite Series)
• Front control arm relocation brackets that flatten control arm angles to correct caster and improve handling
• Heavy-duty drag link flip kit to restore proper steering geometry and eliminate bump steer
• Adjustable front track bar and rear track bar bracket for proper axle centering
• JKS Quicker Disconnect sway bar links with greasable poly-flex ball and high-misalignment ends
• Front and rear bump stop extensions calibrated for optimal suspension travel
• Brake line relocation brackets designed to utilize factory mounting points
• Rubicon-specific sway bar link hardware included for electronic disconnect compatibility

This comprehensive kit provides exceptional stability for daily driving, beach cruising, and regular trail use. The control arm relocation brackets are engineered to JKS's high standards for durability and can withstand serious off-road abuse while maintaining refined on-road manners. Requires 17" or larger wheels with 4.5" backspacing (or smaller) for proper steering clearance. Note: 2012-2018 models with 3.6L Pentastar engines may require exhaust modifications for driveshaft clearance at full droop.
