The lips and splitters listed on the website are designed to be compatible with the original body parts of the vehicle rather than aftermarket body parts. This means that they are intended to work seamlessly with the factory-installed components of your vehicle, ensuring proper fitment and alignment. It's important to consider this compatibility aspect when purchasing lips and splitters from KOCF. If you have aftermarket body parts installed on your vehicle, it's advisable to consult with KOCF's customer support or refer to the product descriptions to confirm compatibility with your specific setup.
