Rock Krawler 2018+ Jeep Wrangler JL 2DR 4.5in X Factor X2 (No Limits) Long Arm Suspension - Stage 1

The Rock Krawler X Factor X2 Long Arm system for your 2018+ Jeep Wrangler JL 2-door starts with 4.5 inches of lift, but it's the long arm geometry that really changes how your Jeep handles off-road. This Stage 1 kit is built around Rock Krawler's proprietary "No Limits" adjustable rear upper control arms, which allow for a wide range of pinion angle adjustments without needing to remove the arms. This is a huge help when setting up your driveline angles after a lift, especially with the increased travel these long arms enable.

This system uses heavy-duty, 2-inch diameter, 5/16-inch wall DOM tubing for the long control arms. DOM (drawn over mandrel) tubing is known for its strength and resistance to bending or kinking under stress, making it a solid choice for serious off-road use. The front arms are also adjustable, allowing you to fine-tune your caster for optimal alignment and steering performance. The kit includes all the necessary brackets and hardware to integrate the long arm setup, fundamentally altering the suspension geometry to provide a smoother ride on-road and significantly improved articulation off-road.

When installing a long arm kit like this, pay close attention to setting the correct pinion angles on your driveshafts. The adjustable nature of the Rock Krawler arms makes this process more manageable, but proper setup is crucial for driveline longevity. This Stage 1 kit is designed to be a foundational upgrade, and you can build upon it with additional Rock Krawler components later if you decide to go for more lift or advanced features.
