Very slight convex glass inserts for a little larger field a view with very little distortion. The Axia Alloys 5″ convex side mirrors feature a fully adjustable billet arm so that they can be mounted on both horizontal and vertical bars of any angle. This is the 1.5″ extended arm version of these mirrors for a total arm length of 4.25″ to the center of the 5″ Diameter mirror. These extended arm mirrors work great on the Cages that have the narrow A pillars with wider B an C pillars behind them. The Black e-coat, clear anodized, and satin mirrors are now ALL supplied with a black powder coated mirror body. We no longer sell the chrome mirror bodies. Only the mirror arms are changed when you select a specific color.
