Description

This 3.5-inch X-Factor Lift Kit System from Rock Krawler Suspension is designed to enhance the off-road capability and appearance of your vehicle. It provides a 3.5-inch lift while maintaining proper suspension geometry and handling. Key features often include high-clearance lower control arms, adjustable track bars, and various mounting brackets. Proper installation requires blocking and securing the vehicle, wearing safety glasses, and using Loctite on all hardware. Limiting straps are recommended to prevent over-extension of the suspension. The system balances on-highway ride quality with off-road articulation.
