Temple length on the Ray-Ban 4298 Aviator runs 140mm, with metal arms curved into a plastic front — this aftermarket pair matches that curve and length, so the hinge seats the way it did from the factory, rather than the straighter geometry found on square Ray-Ban sunglasses. Matching the plastic-hinge fit is as important as matching the curve, since a metal arm sized for an all-metal frame won't necessarily turn smoothly in a plastic socket.

The metal-to-plastic hinge on frames like the 4298 tends to wear at the plastic side first, since it's the softer material of the two. If the arm feels like it's grinding rather than pivoting smoothly, that's the socket wearing rather than the metal arm itself, and a replacement arm alone usually restores a clean action. A dry, gritty feel right after fitting is often just built-up residue in the socket rather than a fault with the new arm.

Frequently asked questions

How do I know these arms will fit my Ray-Ban frame?

These arms are made specifically for the 4298, matching its 140mm length and Aviator hinge design, so they attach to your existing screws and hinge without any filing or adjustment needed.

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 4298 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.

Is it worth buying new arms instead of a whole new frame?

Replacing both arms on the 4298 costs from €26.95 with free worldwide shipping, far less than a new frame, and it's backed by a 3-year warranty against manufacturing defects on the 140mm hardware itself.

Can I replace just one arm, or do I have to buy both?

You can order a single side if only one arm on your 4298 is broken or scratched, or buy the pair if both need replacing — either way they match the 140mm length exactly.
