I asked my local dealership if I needed a 2.5" lift and they wanted me $900 to install these spacers to calculate. I decided to save my money and let them do the work themselves. They are perfect for those who want to use slightly larger tires on their Jeep and are not looking for a functional change but more of an aesthetic modification. In fact, they're relatively easy to fit without the lift kit, but that makes them a bit more labor intensive. I switched from the stock 255/75 R18 to 285/65 R18 - so although it looks like there's only a minor change from the photos, there is actually quite noticeable in person or when trying to jump in. Now it looks like a bad @ss tank and I love it.
