1. Loctite and tighten all bolts and nuts. They are not tight from factory, only loosely put together.

2. Try not to release pressure from the brake system. They are not easy to bleed the air out of them. There are tricks to make it easier, but it's best to just avoid depressurizing.

3. If you have any questions about installation please contact us. It's best to play with the spacing and see how everything goes together. If there are any issues or things that don't seem straight forward let us know.

4. This is a custom part, we cannot guarantee fenders will fit unmodified, other wheels will fit, original OEM risers will fit, tires will fit, etc.
