Radius arms locate the front axle on a Ram HD solid-axle front end; tubular replacement arms correct caster/geometry after a 4.5-6in lift so the truck drives straight and tires wear evenly.

why this one — This kit is explicitly built to correct geometry on 4-6in lifted 2019+ Ram 2500/3500 trucks, complementing a lift kit in that height range from ReadyLift or another brand.
