R2 means 2.56:1 gear ratio.
Since you are wanting to install a posi and 3.42 gears, you can either get a new carrier/gears and have them installed in your axle or you can buy a complete axle with posi/gears. I think it is easier to buy a complete rear with the gear ratio you want as opposed to buying a carrier, gears, installation kit, and paying someone to put it together (it's not a job many people can do themselves). Just my opinion.
