JKS JSPEC185KFP J-Krawl 2.5in Lift Kit Jeep Wrangler JL 4-Door Fox 2.0 IFP HD Coils Rubber Bushings

The JKS JSPEC185KFP is a complete 2.5-inch J-Krawl suspension lift system engineered for the 2018–2023 Jeep Wrangler JL 4-Door. Designed for maximum articulation and adjustability, this full-system kit includes dual-rate heavy-duty rate coil springs, Fox 2.0 IFP Performance Series shocks front and rear, all eight control arms with factory-style rubber bushings, an adjustable front track bar, rear track bar bracket, front sway bar Quicker Disconnects, and bump stop extensions.

Key Features:

• Fox 2.0 IFP Performance Series Shocks — Front and rear shocks are specifically valved by JKS engineering for this suspension system, delivering improved compression and rebound response both on- and off-road
• Heavy-Duty Rate Dual-Rate Coil Springs — JL 4-door tuned JSPEC coil springs provide a smooth, controlled ride on pavement while delivering maximum off-road flex and axle stability
• Full 8-Control-Arm System — Front and rear, upper and lower J-Flex adjustable control arms built from 2-inch x .250-wall DOM tubing optimize driveline and suspension geometry for proper caster, pinion angle, and wheelbase
• Factory-Style Rubber Bushings — Maintenance-free rubber bushings come pre-installed at both ends of every control arm, engineered to reduce NVH (Noise, Vibration, and Harshness) for a quiet, controlled ride in any environment
• Adjustable Front Track Bar — Corrects axle centering under the vehicle after lift installation
• Rear Track Bar Bracket — Maintains proper rear axle positioning for safe, predictable handling
• Front Sway Bar Quicker Disconnects — Allow for increased off-road articulation and can be reconnected for on-road driving
• Bump Stop Extensions — Front and rear extensions properly limit suspension up-travel to protect shocks and other components
• USA Made — All JKS components are manufactured in the United States using premium-grade materials

The J-Krawl system builds off the Jeep's factory suspension mounting points and upgrades the entire suspension front to rear. The JKS engineering team carefully dialed in the Fox shock valving and spring rates to suit oversized wheels and tires, allowing fitment of up to 37x12.50 tires on Rubicon models or 35x12.50 tires on non-Rubicon models.
