The Ray-Ban 4331 Original Replacement Arms-Temples are a pair of genuine Ray-Ban replacement arms, right and left, for the Ray-Ban 4331 frame. This is not a complete pair of glasses: you receive the two temples only, so you can replace a broken, bent or lost arm and keep wearing your own sunglasses. They are made of plastic, just like the arms fitted to this model at the factory.
These arms fit the Ray-Ban 4331 frame, the same model they are made for. If you are unsure about the model, length or color, send us a photo of the inscription on the inside of the arm and we will confirm which ones you need before you order.
As original Ray-Ban parts, they come with a 3-year warranty against manufacturing defects.

We only show reviews for this product. If you've already bought it, tell us how the fit, color and installation went.
The price is for a complete pair: original Ray-Ban right and left arms.
The length usually appears at the end of the inscription on the inside of the arm. Select the same measurement shown on your current frame.
No. Screws are offered as an optional add-on because many frames allow you to reuse the existing ones.
Original replacement arms may use a different manufacturing number, even though their shape, size, color and compatibility match the RB4331.
You can, but we recommend selecting the frame's color code to keep a uniform finish.
