We sell SRS roof airbags for most if not all current vehicles and have one of the largest inventories of left side roof airbags in the industry. All the airbags we sell are OEM (Original Equipment) used airbags that are in class A condition. In addition we certify all airbag parts by our own internal inspection and certification process. We carry OEM manufactured curtain airbags for two door or four door model and for all types of truck cabin, like regular, extended or crew cabs. The airbags will have different lengths if you have a regular, extended or crew cab truck. When these options are available you will see the details defined in the description for each part. In most cases there is only one curtain airbag on each side of the vehicle. However, there are limited models, such as extended SUV 's where they will also have a separate rear curtain airbag to cover the extended portion of the vehicle. In this scenario you will need to purchase both the front and rear curtain airbag if both deployed.
