Rock Krawler JL45X2PLA-4 4.5 Inch X Factor X2 Pro Long Arm Suspension System

The Rock Krawler JL45X2PLA-4 is a 4.5-inch X Factor X2 Pro Long Arm Suspension System engineered for serious off-road performance. Rock Krawler's X Factor long arm platform dramatically extends the radius arm geometry, delivering superior axle articulation, improved approach and departure angles, and a smoother, more controlled ride on and off the trail.

The X2 Pro series builds on Rock Krawler's proven long arm architecture by incorporating heavy-duty components designed to handle extreme trail abuse. The long arm design repositions the control arms for a flatter arc of travel, which reduces pinion angle changes and bind throughout the suspension cycle — a critical advantage when navigating rock crawling terrain.

Key Features:

• 4.5-inch lift height for increased ground clearance and larger tire fitment
• Long arm design for dramatically improved axle articulation and geometry
• X2 Pro-grade components for heavy-duty off-road use
• Engineered to reduce driveline vibration and pinion angle issues
• Designed for use with aftermarket shocks (shock options may vary by configuration)
• Precision-engineered brackets and hardware for a secure, reliable fit
• Rock Krawler's industry-recognized suspension geometry expertise built in
