What I want to know is are the bars the same? Are the packaged husqvarna bars that come from lowes or rural king the same as dealers? For example I'm thinking of buying a 72 links 18" .325 .050 bar and chain from lowes for my Husq 55, but would it be the same as say an 18" bar that comes on a new 562xp? Are they the same 18" bars everywhere or is it like comparing a power match to a low kickback?
