King Ranch seats have always been some of the nicest seats that Ford has produced. On day one the seats were bright, soft, and had a natural feel. Fast forward 10 or 15 years and the seats have begun their unsightly exquisite aging process losing their original appeal. After years of use the seats can become quite seasoned, and without proper care the seats are sure to become worthless. Check out these photos below showing what CAN happen to King Ranch leather if it's left untreated.

Whether you are a current owner, or if you're just looking into doing a King Ranch Conversion, there are a few basics to King Ranch Care that you need to know.

  1. The product you use matters. There's a big difference between the Brands you find at Walmart and the specialty products you can find online. King Ranch even sells their own special King Ranch Leather Conditioner, we tried it but it is over priced and didn't give us the expected results.
  • Our recommendation: Chemical Guys Leather Care Products. The Cleaner & Conditioner are used first, and then use the Protective Serum to finalize the job.
  • This isn't a once a year deal. We recommend a good cleaning every 3-6 months depending on use and climate.
  • While you're conditioning your seats, they may change color. 1999-2007 Super Duty and 1997-2008 Ford F-150 King Ranch leather will turn almost black. This is normal until they dry.
  • If your leather has a red hue to it, as seen in the 2008-2011 Super Duty, it will darken but it won't turn black.

Here is an actual excerpt from a 2005 F250 King Ranch Owners Guide:

Your vehicle is equipped with seating covered in premium, top-grain
leather which is extremely durable, but still requires special care and
maintenance in order to ensure longevity and comfort.
