When deciding which parts replacements you should buy for your suspensions & you must choose between OEM & aftermarkets parts. OEM stands for Equipment Original Manufacturer, which means that parts are manufactured by the selfsame company that produced your vehicle.
Aftermarket parts are designed by a different company & are intended to be compatible with a variety of makes vehicles & models. Aftermarket, parts although they are short costly than OEM parts, they are not designed to the exact specifications of your vehicle, so they will not 'fit' as well as OEM parts.
