Will these mount at my truck's factory attachment points?

Yes. These step bars are designed to mount at existing factory locations on extended-cab models. No drilling, frame welding, or custom brackets needed.

Do I need to install special fasteners?

The step bars use factory mounting points, but you'll want to verify bolt size and torque specs against your vehicle's service manual before final tightening to ensure safe, secure installation.

What's the difference between these and full-size cab step bars?

These are trimmed and positioned specifically for extended-cab geometry. The step height and mounting angle are optimized for that body style, so fitment and angle won't match a full-size cab version.
