"If you have lifted your truck more than 2.5"" and your lift kit didn't include radius arm drop brackets, then you'll want to get yourself a set of ReadyLIFT radius arm brackets. When you lift your truck past that 2.5"" mark, you change the radius arm angle which causes a conflict in spring position and axle positioning. ReadyLIFT has designed drop brackets to correct this problem. They even have a bracket kit that comes with a 1"" lower spring spacer to allow you to increase the lift height of a 2.5"" leveling or lift kit while maintaining the factory geometry. ReadyLIFT radius arm brackets are made from high quality steel and install using your existing frame pockets. This makes mounting very simple and easy. Just like all other ReadyLIFT suspension components, these radius arm brackets & spacers are made in the USA and backed by a limited lifetime warranty. | ReadyLIFT Radius Arm Bracket Kit 67-2550"
