Replacement Temple Arms for Ray-Ban RB3578 – Metal 140mm
Replacement Temple Arms for Ray-Ban RB3578 - Metal 140mm

The SunglassRevivers standard

compatible lenses, built like they belong there

We obsess over one thing: that your revived sunglasses look, fit and perform like the day you bought them. Every lens leaves our workshop only when we would wear it ourselves.

01

Optical-grade clarity

Distortion-free lenses cut from hard-coated polycarbonate (CR39 for clear options) — crisp edges, true colours, zero eye strain.

02

Cut to your exact model

Precision-machined to the curve and bevel of this frame model, so they click in at home and sit flush — no gaps, no rattle.

03

100% UV400, every colour

Full UVA/UVB protection is built into the material itself — and polarized options cut reflected glare from roads, water and snow.

04

Backed for 3 full years

Quality-checked before shipping and covered by our 3-year warranty against manufacturing defects — at a fraction of the price of a new pair.

Independently manufactured compatible parts — not products of the frame brands. That independence is what lets us focus everything on quality and price.

DETAILS

about this product

The RB3578 pairs an aviator-style metal front with a 140mm temple arm, and a compatible replacement has to match both to sit correctly. Because the front is metal too, a mismatched finish on the arm tends to be more noticeable here than on frames with a plastic front.

A bent or loose temple is the most common issue on aviator frames like the RB3578, while the front lens and bridge usually stay in good condition through years of use. Swapping the arm on its own is normally all it takes to get back to a proper fit. An aftermarket 140mm arm matched to the metal finish keeps the repair simple and avoids replacing parts that are still working fine. Checking both arms together, rather than just the one that feels loose, avoids having to repeat the same repair again a few months later.
