Drop links are short metal rods with joints known as 'bushings' at each end. The purpose of drop links is to connect the anti-roll bar in a car's suspension to the rest of the suspension structure. Some important information for selecting the correct drop links is the type of links needed; fitment position, length, width and date limitation of the unit. As car manufacturers regularly update certain peripherals and design of their models, some drop links will only be suitable for particular models of certain years.
