RB8041 Aviator is built entirely in metal, front and arms, with 140mm temples curved to the classic aviator sweep. This aftermarket pair matches that curve and length precisely, so it hinges into the front the same way it did from the factory, rather than the straighter profile used on Ray-Ban's square or rectangular sunglasses. Getting the sweep right matters more on an all-metal aviator than on a plastic-front model, since there's no softer material to disguise a slightly off curve.

All-metal aviators like the 8041 are simple to maintain but rely entirely on the hinge screw staying tight, with no plastic bushing to absorb play. If the arms have started to droop below level, that screw is almost always the cause, and tightening or replacing the arm is a quick fix rather than a sign the frame is worn out. Keeping both arms folded evenly when the sunglasses are in their case also reduces the hinge strain that leads to this kind of wear over time.
