RX6489 Aviator brings the classic aviator curve to a prescription frame, with an all-metal front and 140mm arms shaped to follow that sweep. This aftermarket pair keeps the same curve and length, so the temple meets the front the way it did from the factory, rather than the straighter arm used on Ray-Ban's square eyeglass models. Matching that curve is the detail that matters most here, since a straighter substitute would sit oddly against an aviator front.

Because the aviator curve runs the length of the arm rather than just at the hinge, a slightly different bend is more noticeable here than on a boxier frame. If the metal has lost its shape or discolored near the hinge, replacing the arm restores the aviator line without needing new lenses. Eyeglass frames like this one also see more daily wear than sunglasses, so it's worth checking the hinge tension every few months rather than waiting for a visible problem.

Frequently asked questions

Are these official Ray-Ban replacement parts?

These are compatible aftermarket arms, independently produced to match the 6489's hinge and 140mm length. They aren't manufactured or supplied by Ray-Ban, just built to the same measurements so they attach correctly.

What if the arms arrive and the hinge doesn't line up with my frame?

Because each pair is listed against a specific model, in this case the 6489, mismatches are rare, but you're covered by a 14-day return window if the 140mm arms don't align with your hinge.

What material are the arms made from, and will the color match my frame?

The arms are molded in an acetate or metal finish that matches the Aviator style of the 6489 closely, though very slight shade variation is possible since they're independently produced as separate aftermarket parts rather than cut from the same batch as the frame.

Do I need a specific screwdriver to attach these myself?

You'll need a small eyeglass screwdriver, typically included in basic repair kits, to remove the old hinge screw and attach the new 140mm arm to your 6489 frame — the whole swap usually takes under five minutes.
