All RAM mounts and cradles come standard with a one inch diameter double ball and socket system. These custom made cradles are designed to withstand more than 50g's of shock and will hold your hand held device rock solid, even in the harshest of conditions. The patented rubber ball and socket design will protect the electronics from damage due to vibration. All these RAM components are 100% interchangeable so if you decide to switch GPS units simply switch out the Gps cradle necessary to make the change. Additional components are available so that your GPS can be quickly and easily moved from your windshield, handlebar, deck, or any other location that you want. Convenience and quality without a big dollar expense is what RAM brings along with lifetime warranties, electronic protection, and perfect viewing angles.
