Will these mount at the factory attachment points or do I need to drill?

These mount at factory rocker and upper fender points — no drilling required. Use existing bolt holes and fasteners rated for your vehicle's service manual specs.

Do I need to prep or paint the textured finish before installation?

No. The textured surface ships ready to bolt on. If you prefer a different color or finish, light sanding with 220-grit or higher prepares it for primer and paint.

What size tire and wheel packages will these support?

Clearance depends on your suspension setup and backspacing. Test-fit before finalizing your wheel and tire choice — pocket flares work best with modest lift kits and moderate offsets.
