yeah the bead rim is continuous
But the lock ring has a gap
The bead rim and lock ring and the main rim part makes it 3 piece rim not a two piece rim which I’m also familiar with
The AR type has 3 parts to it
Front bead rim, the main back part and the square cross section lock ring
A RH-5 is the two part rim and they separate in the center of the rim behind the center portion so when bolted to the truck there are no parts that could go flying into the street if they fail
