Due to their unique design, the vehicle chassis and powertrain can be serviced or replaced without removal of the Radius Arm Drops. Constructed out of 1/4" Cold Rolled Steel and CNC formed, these precision components rotate your axle back to OEM settings, locating your lower coil perch angles where they were intentionally designed; this also alleviates the coil bowing that is encountered when you lift the front and don't address the coil bow issue, something that will never be truly addressed with a "coil only" approach. Carli Radius Arm Drops for 2013+ RAM trucks will keep your investment driving like the day it left the showroom floor. Fits 2014-2018 Ram 2500 4x4 Trucks & 2013-2018 Ram 3500 4x4 Trucks.
