Vehicle Fitment: Optimized for the Jeep JL Platform
This complete system is engineered for the 2018–2025 Jeep Wrangler JL 4-Door with a gas engine and 4WD driveline. The setup is a direct bolt-on replacement that delivers an aggressive stance and improved suspension geometry without compromising OEM ESC functionality.

Progressive Dual-Rate Coil Springs
Skyjacker’s coil spring design is more than just a lift—it’s a dynamic two-stage performance enhancement. The first stage, or Flex Rate, expands under full droop, keeping the coil seated and tires engaged with terrain. The second stage, or Ride Rate, activates only after the coil compresses beyond the flex rate, enhancing stability during high-load driving.
Coil Spring Benefits
- Dual-rate long-travel design for balanced flex and ride quality
- Flex Rate keeps springs seated at full droop
- Ride Rate adds control under compression and improves handling
- Side-specific rear coils tuned for Jeep JL geometry
ADX 2.0 Remote Reservoir Shocks
At the heart of this system are the ADX 2.0 Aluminum Monotube Shocks with External Remote Reservoirs. Using race-derived technology, these shocks feature full-displaced valving, Teflon-banded pistons, and Internal Floating Piston (IFP) technology to eliminate cavitation under high-speed or high-stress conditions.
Shock Technology Highlights
- Aluminum monotube body ensures superior heat dissipation
- Remote reservoir separates oil and gas via IFP for stable damping
- Ideal for high-speed off-roading and low-speed crawling
- Teflon-banded piston provides smooth response and long service life
- Quick-reacting damping improves handling and terrain response
Extended Sway Bar End Links and Bump Stop Spacers
Included in the system are extended-length sway bar end links with HD OEM-style rubber bushings and bolt-on front/rear bump stop spacers. These components ensure safe suspension travel while preserving factory safety systems like ESC (Electronic Stability Control).
Added Suspension Components
- Front and rear sway bar end links for full suspension articulation
- Pressed-in heavy-duty rubber bushings for longevity and strength
- Bolt-on axle bump stop spacers protect shocks and mounts
- Maintains suspension geometry within OEM specs
