Rock Krawler 2019+ Jeep Wrangler JT 4.5in X Factor X2 (No Limits) Trail Runner Long Arm System

Rock Krawler is known for building serious suspension components for off-road vehicles, and this X Factor X2 (No Limits) Trail Runner Long Arm System for your 2019+ Jeep Wrangler JT is a prime example. This is a comprehensive long arm upgrade designed to give your JT significantly improved suspension geometry and articulation for tackling challenging trails.

This system includes their X Factor front and rear long arms, which are built from solid 1.75 inch OD x .375 inch wall DOM tubing for exceptional strength. The X Factor arms utilize Rock Krawler's proprietary RRD (Rock Ready Double) adjustable lower flex joints, offering a wide range of motion and durability. The 'No Limits' designation means this system is designed for maximum travel and articulation, often requiring modifications for full potential. The Trail Runner aspect highlights its focus on off-road performance, providing a more comfortable and controlled ride over rough terrain compared to stock or basic lift kits. This kit is engineered to work with 4.5 inches of lift, allowing for larger tires and increased ground clearance.

When installing a long arm system like this, expect a significant transformation of your Jeep's suspension. The longer control arms correct caster and pinion angles, which are crucial for proper driveline operation and on-road manners after a lift. This system is designed to be a complete solution, but always refer to the manufacturer's installation instructions for specific details and any additional components that may be recommended for your build.
