OpenAir Motorsports 99-18 Silverado/Sierra Shackles and Hangers have been designed with the ideal pivot location to allow the leaf springs to cycle smoothly from bump to droop without binding. They also feature a tab allowing them to be bolted to the bottom of the frame rails, for a total of (5) fastening bolts per side. This 5th bolt offers a significant amount of support to the shackle and hanger when side-loading the rear suspension.
