They call iit the Magnum because of it's rugged design. Every component has been beefed up. Unlike other flimsy mirrors, ours are made super-tough. Head size is: 5-1/2" x 3". Magnum Mirrors have a beautiful chrome-plating & a style all their own. (Mirrors sold in pairs).

Note: Mirror adapters (STR-0SS56-10-99) are required for installation and sold separately.
