You've probably seen the seat belt extenders with a buckle on one side and a tongue on the other side. While convenient, that design is extremely dangerous and likely to fail in an accident. The problem lies in the mismatched buckle/tongue combo (aftermarket tongue used with an OEM buckle). Just because the tongue clicks into your factory buckle does not mean it will stay together under load. We don't offer that style. What we do carry is a bolt in extender that is certified to FMVSS 209/302 safety standards. This bolts in line with your seat belt's end fitting and is designed to survive an accident and keep you safe!
