Do these fenders require modification to my door jambs or rockers?

These are designed as over fenders to mount cleanly to existing factory attachment points. Before installation, verify your vehicle's mounting locations match the standard door jamb and rocker line. Minor adjustments to fastener placement may be needed depending on your specific setup — test-fit first and measure twice.

What prep work is needed before painting?

Sand the surface with appropriate sandpaper and wipe clean before applying your base coat and clear. FRP requires proper surface preparation to ensure paint adhesion — do not skip the sanding step. Once prepped, treat these like any factory panel.

Will these affect my tire clearance?

The Black Series profile extends the wheel arch outward, so verify your current tire and wheel dimensions will clear the inner edge of the fender. If you're running wider wheels or aggressive offsets, check clearance before committing to installation — these are designed for stock or moderately aggressive setups.
