Do I need fasteners to mount these, or are they included?

Hardware is not included with this set. You'll need to source fasteners compatible with your existing factory mounting holes. Refer to your vehicle's service manual for the correct bolt specifications and torque values.

What prep work is required before painting?

Sand and prep the surface with standard automotive sandpaper before applying your chosen primer and topcoat. Follow your paint manufacturer's instructions for surface prep—clean off any dust and ensure the surface is dry before finishing.

Will these fenders affect my wheel fitment or tire clearance?

The 2-inch width increase is designed to accommodate stock and moderately wider wheel setups. Verify your specific wheel and tire combination against the new fender opening before final installation to ensure adequate clearance during suspension compression.
