The tubular rear lower control arms are made out of two inch DOM tubing and are tig welded. Spherical aircraft bearings on the frame side and a Del-A-Lum bushing on the rear end side. This allows the rear end to pivot without bind due to the bearing being installed on the frame side. Del-A-Lum bushings provide lateral control. Rear adjustable upper arm makes setting pinion angle easy. Linear rate 3/4" drop springs offer: Consistency - As a linear is compressed, the resistance increases per inch equal to that of the rate. For example, if a spring is rated at 300 pounds per inch, for every inch of travel the spring compresses, the resistance increases 300 pounds. Therefore, one-inch of compression will provide 300 pounds of resistance, two-inches 600 pounds, and three-inch 900 pounds. OEM springs, however, do not increase in the same fashion. Tubular Rear Adjustable Frame Supports mean you can add support between the upper frame cross-member and lower arms pivot point for extra rigidity! Finally, dual adjustable High Performance Shocks Feature 19 positions of compression and 19 positions of rebound adjustment for a total of 361 different valving combinations! 1-1/8" Rear Stabilizer Bar.
