Frequently Asked Questions
Do these mount at factory rocker points with no drilling?
Yes. These bolt to the existing Super Duty extended cab mounting locations — no modification needed. You'll use your truck's factory attachment points.
Will these fit a crew cab instead of extended cab?
No. These are sized for extended cab geometry only. Crew cab Super Duties require a different mounting pattern and step length.
What hardware is needed for installation?
The listing doesn't confirm included fasteners. Have metric bolts and washers on hand, and refer to your vehicle's service manual for torque specs before final install.
