Large Metal II is the RB3026's designation, and its aviator front takes a 140mm metal temple arm to match. A compatible replacement needs to hold that length precisely, since this larger aviator size makes an undersized arm more noticeable than it would be on a smaller frame.

As with other aviator styles in this range, the temple tip on the RB3026 tends to wear through or chip before the main arm shows real damage. That small part failing first is usually what pushes people to replace the whole arm rather than patch just the tip. A compatible 140mm aftermarket arm handles both issues at once, without needing a separate tip repair. Checking the tip specifically, rather than assuming the whole arm needs replacing, can save an unnecessary order in some cases.

Frequently asked questions

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

These arms are made specifically for the 3026, matching its 140mm length and Aviator hinge design, so they attach to your existing screws and hinge without any filing or adjustment needed.

My hinge feels loose — will new arms fix that, or is it the frame that's worn?

A new 140mm arm includes its own hinge barrel, so if the wobble is coming from worn threading on the arm side of the 3026, replacing it usually restores a snug, tight fold.

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 3026 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 3026 frame — the whole swap usually takes under five minutes.
