JKS JSPEC189FRS J-Krawl 3-Inch Lift Kit with FOX 3.0 Factory Race Series IBP Shocks & Standard Rate Coils

The JKS JSPEC189FRS J-Krawl 3-Inch Suspension Lift Kit is a complete, top-tier off-road suspension system engineered for the 2018–2023 Jeep Wrangler JL 2-Door. Designed for maximum articulation, strength, and adjustability, this kit represents a full overhaul of the factory suspension from front to rear using factory mounting points as its foundation.

At the heart of this build are the FOX 3.0 Factory Race Series (FRS) Internal Bypass (IBP) shocks — the pinnacle of FOX's off-road shock technology. The front position features a Remote Reservoir (R/R) setup with Dual Speed Compression (DSC) adjustment, while the rear uses a Piggyback (P/B) reservoir with DSC adjustment. Position-sensitive internal bypass technology delivers a plush, controlled ride under normal conditions while ramping up damping force to prevent harsh bottom-outs during extreme off-road use.

FOX 3.0 FRS IBP Shock Features:

• Large 3-inch diameter hard-anodized aluminum bodies with 7/8-inch shafts
• Race-bred pistons and valving for superior compression and rebound response
• PTFE-lined spherical bearings, proprietary racing oil, and high-temp Viton® seals
• Separate high- and low-speed compression adjustments via DSC for precise tuning
• Finned reservoir bodies to dissipate heat and maintain optimal fluid temperature
• Specifically custom-valved by JKS Engineering for this suspension system and oversized tire combinations

The J-Krawl system includes all eight adjustable control arms — front and rear upper and lower — built from 2-inch x .250-wall DOM tubing with factory-style rubber bushings to reduce Noise, Vibration, and Harshness (NVH) for a quiet and controlled daily driving experience. Coil springs are standard-rate dual-rate units specifically wound and tuned for the 2-door JL application.
