What fasteners do I need to install these fenders?

Over-fenders bolt to the existing body structure at factory mounting points. You'll need hardware appropriate to your OEM fastener size and thread pitch — refer to your vehicle's service manual or contact a dealer parts specialist to confirm the exact bolt specification for your installation.

Do these require painting before installation?

Yes. The panels ship in raw FRP condition, which means they have been prepared for finishing. Sand the surface with appropriate grit, apply your choice of primer, and topcoat to match your vehicle's paint. Finish them before final installation to avoid paint overspray on mounted panels.

Will these fit over my factory fenders without trimming or cutting?

Over-fenders are designed to bolt directly over the existing body without cutting the OEM panels. However, your tire size and suspension setup determine final clearance. Verify that your current wheel and tire combination has adequate space inside the expanded wheel opening before final fastening.
