Buy Ford F-350 Super Duty Side View Mirrors

Background Info

Ford's F-350 Super Duty truck uses large side-view mirrors-also called towing mirrors, door mirrors, wing mirrors or mirror assemblies-to give drivers a clear look down the tall body and past extra-wide trailers. Modern PowerScope units power-fold, power-telescope about 3 inches for towing, add heaters, LED signals, spotlights and Blind-Spot Information System (BLIS) alerts, all while meeting federal field-of-view rules (FMVSS 111) and commercial-vehicle guidelines. Keeping the glass clean, the motors working and the mounting bolts tight protects safety, avoids fines and helps the truck hit its class-leading 40,000-lb gooseneck-towing target.

Mirror Types

• Standard door mirror - fixed width, manual fold; best for daily driving.
• Trailer-tow PowerScope mirror - power-fold,telescopes out ~75 mm; includes lower convex "spot" lens. (Ford Service Content)
• Convex add-on lens - sticks to outer corner; widens rear view.
• Camera-integrated mirror - factory option pairs with 360-degree Trailer View so you can watch horse stalls or cargo. (MotorTrend)

Factory Features

• Heated glass & auto-defog tie into the rear-defrost button for frost-free mornings. (Ford Service Content)
• LED turn, puddle and security lamps built into the housing light the ground at night. (Ford)
• Blind-Spot Information System (BLIS) lights an amber icon in the mirror when radar sees a car or when trailer sensors detect a vehicle alongside your rig. (Ford Motor Company)
• Trailer-length blind-spot sensors plug into the 7-pin harness and extend warnings the full length of the trailer. (MotorTrend)

Safety Tech

FMVSS 111 says the driver must see a 20-degree horizontal field and a point 200 ft behind the truck; the F-350 mirrors exceed this by combining flat and convex glass. IIHS studies show blind-spot detection cuts lane-change crashes 14 percent. (IIHS-HLDI, IIHS-HLDI) MotorTrend notes Ford's long-trailer blind-spot kit eliminates common towing blind spots.

Legal Requirements

Federal Motor Carrier Safety rules treat a cracked or loose mirror as "disabling damage," meaning the truck must be removed from service until fixed. (FMCSA) Many U.S. states and Canadian provinces also require mirrors to extend far enough to see the entire lane behind a trailer wider than the truck. Check local commercial-vehicle codes before hauling.

When to Replace

• Broken glass, faded chrome or internal moisture.
• Motor won't fold/telescope or heater inoperative.
• Plastic shell cracked or vibrates above 50 mph.
• Upgrading from basic mirror to trailer-tow style for wider field of view or BLIS.

Replacement Tips

1. Disconnect the truck battery.
2. Pop off the interior trim cap; remove three 10 mm nuts; support the mirror.
3. Unplug the multi-pin connector (documented in Ford's 2022-2025 manuals). (Ford Service Content)
4. Reverse steps with new mirror; torque nuts to 80 in-lb.
5. Re-enable the memory presets through the driver-door module.

Upgrade Ideas

The 2024-2025 trailer-tow mirror adds LED spotlights, security approach lamps and built-in bed-camera feed. (Ford Motor Company, Ford Motor Company) Aftermarket shells can be paint-matched or wrapped, but ensure any add-on lights meet SAE/DOT labeling.

Care & Maintenance

• Wash glass with ammonia-free cleaner; avoid paper towels that scratch.
• Spray moving joints with silicone twice a year.
• Cycle power-fold and telescope weekly so the motors don't bind.
• Check BLIS sensor lens for mud; a dirty sensor can turn the system off. (Ford Media Center)

Environmental Note

Re-using intact housings and replacing only mirror glass saves plastic; Ford's parts catalog lists separate glass and motors, reducing waste. (Ford Motor Company)

Frequently Asked Questions

Q: How far do the PowerScope mirrors extend?
A: About 3 inches (75 mm) beyond the normal position, giving clearance for an 8-ft-wide trailer. (Ford Service Content)

Q: Will a 2024 F-350 mirror fit a 2019 model?
A: The three-stud mounting pattern matches, but you must update wiring if you want BLIS, cameras or power-fold to work.

Q: Does blind-spot detection really help?
A: Yes. IIHS found lane-change crashes drop roughly 14 percent when vehicles have blind-spot warning. (IIHS-HLDI)

Q: Can I fold the mirrors in manually?
A: Yes-if power-fold is installed, you can still press them in gently by hand without damage.

Q: Are the mirrors heated automatically?
A: They turn on with the rear-window defroster switch; no separate button is needed. (Ford Service Content)

Q: What torque do the three mirror nuts need?
A: 80 inch-pounds is the common spec shown in Ford service manuals for 2017-2025 trucks. (Ford Service Content)

Q: Is there a law about using towing mirrors?
A: Federal rules require mirrors that let you see the full width of the trailer and 200 ft back; many states fine drivers if their view is blocked. (FMCSA)

Q: How do I recalibrate power-fold after battery change?
A: Hold the fold switch for five seconds, release, then extend; the control module resets positions automatically.

Q: Can I replace just the glass?
A: Yes-snap-in replacement glass is listed in Ford's parts guide and keeps the factory housing in place.

Q: Does the Super Duty mirror include cameras?
A: 2023-up mirrors can carry a forward-facing bed camera and connect to the 360-Trailer View system. (MotorTrend, MotorTrend)
