High quality, high strength lowering shackles. They are a great upgrade to replace the factory shackles where the bushing is prone breaking down to failing. The shackles allow for additional down travel when paired with long travel leaf springs. They are CAD designed and constructed using 3/16" thick steel. The shackles drop the rear ride height 3 inches to help level the vehicle. They also have grease ports to easily service the polyurethane bushings.
