JKS JSPEC185KFA J-Krawl 2.5in Lift Kit with FOX 2.0 Adventure Series Shocks and HD Coils

The JKS JSPEC185KFA is a complete 2.5-inch J-Krawl suspension lift system for the 2018–2023 Jeep Wrangler JL 4-Door, configured with factory-style rubber bushings, FOX 2.0 Adventure Series shocks, and HD-rate dual coil springs. Engineered for maximum articulation, strength, and adjustability, the J-Krawl system delivers a comprehensive front-to-rear overhaul of your factory suspension using Jeep's existing mounting points.

The FOX 2.0 Adventure Series shocks are custom-valved specifically for this JKS lift to optimize compression and rebound performance across all terrain types.

HD coil springs utilize a progressive dual-rate design, meaning the spring rate increases as the spring compresses — delivering a plush ride at highway speeds with added support under heavier loads. HD-rate springs are ideal for Jeeps equipped with winch bumpers, full-size spare tires, roof racks, or other added accessories.

Key Features:

• 2.5-inch lift with full front-to-rear suspension geometry correction
• Eight J-Flex adjustable control arms (front/rear, upper/lower) for maximum articulation
• Factory-style rubber bushings for reduced NVH and maintenance-free operation
• FOX 2.0 Adventure Series IFP monotube gas shocks, custom-valved for this system
• HD-rate JSPEC dual-rate progressive coil springs, tuned for 4-door applications with added load capacity
• Adjustable front track bar and rear track bar bracket for precise axle positioning
• Front sway bar Quicker Disconnects and rear sway bar links for improved trail articulation
• Front and rear bump stop extensions to properly limit suspension up-travel
• Brake line brackets and all required hardware included
• Allows fitment of 37x12.50 tires on Rubicon models or 35x12.50 tires on non-Rubicon models

The J-Krawl system provides full adjustability to dial in front caster, rear pinion angle, and overall vehicle wheelbase. Note: an aftermarket front driveshaft is strongly recommended due to the additional suspension travel this system enables. Routine maintenance is required.
