The Rock Krawler Wrangler X Factor Long Arm Suspension System design dominates the professional world of rock crawling while still maintaining perfect drivability on the road. The front upper three link control arm is a full length link that keeps caster change to a minimum. The front upper bushing in the differential is replaced with a build a ball joint for maximum articulation and strength. This system features an independent 3 link assembly in the rear for the ultimate flex. The lower control arms feature a high clearance design to maximize ground clearance and cross over angles. All lower control arms are made of 2" O.D., 7/16” Wall DOM alloy steel. Our modular skid plate design clam shells the frame top and bottom. A weld in cradle made from thick laser cut steel will add structure to the rear axle. If you’re looking for the ultimate Long Arm System, look no further.
