All our weather-strip parts are US made or Japanese OEM Original. NO other Asian suppliers or 3rd world manufacturers contracted or used EVER!
Understand that it cost us 10 times the amount of tooling charges to make your weather-strip parts here in the states. Why? One important reason is that we can and do receive certification of the materials used. You can't always trust overseas providers to guarantee the rubber compounds they use so we avoid using anyone overseas.
The 2nd reason is that we work very closely with the die cutters here in the US, sometimes even traveling long distances to their manufacturing plants, to make sure the parts will be faithful to the originals.
It is for these two reasons that some of our parts may cost more than what you may see from other vendors who are using overseas sources.
