This heavy duty truss system is designed to take serious abuse and reinforce your entire axle while also providing a flat surface to mount your upper links. The 1/4" thick truss top incorporates a unique design to strengthen both the axle and provide a low profile link mounting surface. The base truss itself spans about 32.5 inches across the center of your axle. The Jeep Wagoneer Rear Dana 44 has about 18 inches of axle tube on the driver side and about 20 inches of passenger side axle tube. The axle tube diameter is 2.75 inches. Other Dana 44's will measure differently and have differing axle tube diameters. Please ensure your axle meets these dimensions prior to ordering. This kit requires general welding and fabrication skills. This product ships in approximately 1 days
