Duraflex is the name of the material used for the body kit piece.
Duraflex combines fiberglass, plastic, and flex resins to obtain its unique features. Because of these features, Duraflex technology obtains a much higher durability rate than the average fiberglass product, resulting in reduced shipping damages up to 75%.
BUT, if you are talking about:
https://www. duraflexbodykits .com/
and
https://www. duraflexaero .com/
That is just a dot com name owned by Extreme Dimensions, which forwards to:
https://www. extremedimensions .com/
and
https://www. drivenbystyle .com
Which sells body kits using other peoples photos to sell their products because they cannot be bothered to use their own photos, or event recent photos. Some of the bodykit pictures they are using are over 15 years old. They first started selling low quality body kits under the name of Extreme Dimensions and got a bad name because their kits were a copy of a copy of probably another copy. They did not fit well.
They use multiple names:
drivenbystyle
duraflexaero
duraflexbodykits
extremedimensions
and probably other names.
I would use caution when buying from them.
But if you do buy from them, ask that they guarantee the bodykit they are selling to is made with duraflex material. Obviously the fitment cannot be guaranteed, so ask what they provide if the fitment is off by a lot vs being off by just a little.
