Do these fenders require drilling or modification to the original chassis?

No. These fenders are engineered to utilize factory mounting points. Before installation, verify that your vehicle's factory hole locations are clear and in spec, then test-fit the first fender to confirm alignment before final fastening.

What prep work is needed before painting?

Sand and prep the surface with standard automotive preparation steps before applying your chosen finish. This ensures proper paint adhesion and a smooth final appearance.

Will these affect wheel fitment or tire clearance?

The AM-S profile adds width to the fender area. Verify your current wheel and tire package will clear the new bodyline — measure from the wheel center to the new fender edge, then confirm your tire sidewall height maintains adequate clearance under full suspension compression.
