Rock Krawler JL45NL-4D 4.5 Inch X Factor No Limits Mid-Arm Lift Kit for Jeep Wrangler JLU 4-Door

The Rock Krawler JL45NL-4D 4.5-Inch X Factor No Limits Mid-Arm Suspension System is a complete front and rear lift kit engineered specifically for Jeep Wrangler JLU 4-Door Rubicon owners seeking maximum articulation, a bolt-in installation, and proven off-road performance. This system delivers 4.5 inches of lift and is designed to accommodate up to 42-inch tires, depending on model configuration.

The "No Limits" name refers to the specially designed front sway bar links that are fully compatible with the factory electronic sway bar disconnect feature found on Rubicon models. These links feature factory-sized hardware, a CNC-machined billet aluminum center section, and Made in USA FK Bearing heim joints — simply press the button and hit the trail.

Key Features:

• X Factor Series Adjustable Control Arms — Adjustable lower control arms offer 90 degrees of total misalignment, drastically reducing the bind inherent in JL factory lowers
• High Misalignment Adjustable Upper Control Arms — Allow precision caster tuning both front and rear
• Triple Rate Coil Springs — Industry-leading design that provides improved on-road ride quality over factory linear rate springs while maintaining proper free-length for off-road articulation
• No Limits Sway Bar Links — CNC billet aluminum with FK Bearing USA-made heim joints; fully compatible with factory Rubicon electronic sway bar disconnect
• Spring Correction Pads — Included on all Rock Krawler JL systems to reduce spring bow inherent in the factory setup
• Front and Rear Track Bar Geometry Corrections — Perfectly centers the axles for no compromise in on-road handling
• Bolt-In Installation — Complete system designed for a clean, straightforward install
