One of the most important components to be included in our systems, Carli's Radius Arm Drops maintain your vehicle's critical caster and coil geometry. RAM's new suspension setup has proven itself to be quite complex in its idiosyncrasies, and as a result we have engineered a simple solution to overcome the less-desired nuances of the new trucks. Using Chrysler CAD files, we developed a simple-to-install Drop that is truly bolt-on with no welding required. 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.
