<div style="font-family:inherit;font-size:inherit;color:inherit;">My BN2
has matching front Armstrong 6075 shocks. I received a rebuilt 6075
that has the shock body also stamped 6075, but it does not have the
"RX" on the one side as my current ones do. On FB someone suggested
they were made in different countries, one suggested the "RX"
is double action shocks, and another that the "RX" was for
prescription only! Anyone know what the "RX" is? Just
curious.</div>
