Description

The Rock Krawler 4.5" X-Factor X2 Long-Arm (Diesel) System is engineered for Jeep Gladiator JT Diesel owners who demand exceptional articulation and hardcore off-road performance. This system boasts an independent 3-link design for both the front and rear, maximizing suspension travel. It incorporates double adjustable front and rear upper control arms, featuring upsized 14mm hardware and robust 1.25" Pro Krawler joints at each end. The control arms themselves are constructed from chromoly solid steel, designed to withstand significant suspension forces. The rear suspension features adjustable anti-squat with X2 rear suspension geometry, enhancing both rear instant and roll centers for improved performance. The system is meticulously designed to provide a stable, safe, and strong feel whether traversing highways or tackling challenging trails, accommodating both stock and high-horsepower drivetrains.
