This lift kit has never been used. I purchased this kit on eBay to install on my Toyota 4Runner with bigger tires but I decided to go the other direction. I purchased bigger wheels instead and didn't want to raise my 4Runner. Installation instructions are included in the kit. This lift kit is not limited to only the Toyota 4Runner, you can install this on your Toyota Tacoma or Toyota Tundra as well. Call the home# with any questions.
