Owning a 2017 Ford F-350 means dealing with a massive windshield that requires precise wiper coverage for safety. Using the wrong 2017 f350 wiper blade size leads to dangerous streaking, annoying chatter, or even damage to your glass. Factory specifications call for a 26-inch blade on the driver side and an 18-inch blade on the passenger side to ensure full visibility.
This guide details exactly which sizes fit your Super Duty truck and how to verify them before you buy. You will learn the difference between beam and conventional styles, how to install new blades in minutes, and common mistakes that ruin fitment. Follow these steps to restore clear vision during heavy rain or snowstorms without guessing at the auto parts store.
Exact Factory Wiper Dimensions for 2017 F350
Your truck uses two distinct lengths to cover the wide Super Duty windshield effectively. These measurements remain consistent across Regular Cab, SuperCab, and Crew Cab models.
Driver Side Requires 26 Inches
The driver’s side demands a 26-inch blade to sweep the large area directly in your line of sight. This longer length is critical for clearing heavy precipitation from your primary viewing zone. Installing a shorter blade here leaves dangerous unwiped spots near the A-pillar.
Passenger Side Needs 18 Inches
The passenger side utilizes a shorter 18-inch blade. This specific length matches the curvature of the glass on that side while preventing interference with the driver-side wiper. Using a longer blade here causes the arms to collide or the rubber to fold over.
Rear Wiper Availability and Size
Most 2017 F-350 models do not include a rear wiper as a standard feature. You typically only find a rear wiper on specific Crew Cab configurations equipped with a flip-up rear window and washer system. If your truck has this rare option, the rear blade is usually 12 inches, though you should measure it to be sure.
Methods to Verify Your Current Wiper Size
Factory specs are reliable, but previous owners may have installed non-standard parts. Always double-check your specific vehicle before purchasing replacements.
Inspect the Existing Blade Markings
Remove the current wiper arms and look closely at the rubber or metal frame. Manufacturers often stamp the size in inches directly on the blade spine or end cap. Look for numbers like “26” or “18” printed in white or embossed in the rubber.
Measure the Rubber Length Directly
If the markings are worn away, use a tape measure to find the exact length. Measure only the rubber squeegee portion from end to end, excluding the metal hardware or connectors. This ensures you get the active wiping length correct for your 2017 f350 wiper blade size needs.
Consult the Owner’s Manual
Page 247 of the 2017 F-350 owner’s manual lists the factory specifications under the maintenance section. This document confirms the 26-inch driver and 18-inch passenger requirements. It remains the most authoritative source if your current blades are missing entirely.
Choosing the Right Wiper Blade Style
The 2017 F-350 utilizes a bolt-on adapter system, often called a stud mount or pin mount. You must select blades that include this specific connector type for proper installation.
Benefits of Beam Blade Designs
Beam blades feature a frameless, aerodynamic design that applies even pressure across the windshield. They excel in snowy conditions by preventing ice buildup on the frame and reducing wind lift at highway speeds. Popular brands like Bosch and Rain-X offer beam styles with universal stud mount adapters.
Conventional Framed Blade Options
Traditional framed blades use a metal skeleton with multiple pressure points. While generally more affordable, they can trap snow and ice in the exposed frame links. These work well in mild climates but may require more frequent cleaning in winter months.
Winter Blades for Extreme Climates
Winter-specific blades come with a thick rubber casing that encloses the entire frame. This design prevents snow and ice from jamming the mechanism, ensuring consistent wiping in freezing temperatures. If you live in northern states, these are a worthwhile upgrade for your Super Duty.
Step-by-Step Wiper Replacement Process
Replacing wipers on your F-350 takes less than five minutes and requires no special tools. Follow this simple procedure to swap out old blades safely.
Lift the Wiper Arm Safely
Gently lift the wiper arm away from the windshield until it locks in an upright position. Place a towel on the glass beneath the arm if you are worried about it snapping back accidentally. This step gives you clear access to the blade connector.
Release the Old Blade
Locate the small release tab or clip where the blade meets the wiper arm. Press this tab firmly while sliding the blade downward off the hook. Some models require you to press a side button while pulling the blade away from the arm.
Secure the New Blade
Align the adapter on your new blade with the wiper arm hook. Slide the blade upward until you hear a distinct click or feel it lock into place. Give the blade a gentle tug to confirm it is securely attached before proceeding.
Lower the Arm Gently
Carefully lower the wiper arm back down to the windshield surface. Do not let the arm snap down unchecked, as the force can crack the glass or bend the metal arm. Repeat the entire process for the second wiper.
Avoiding Common Fitment Errors
Even with the correct 2017 f350 wiper blade size, simple mistakes can ruin your installation. Avoid these pitfalls to ensure quiet and effective operation.
Selecting the Wrong Connector
Many aftermarket blades come with multiple adapters, but not all fit the F-350. Your truck requires a stud mount or bolt-on connection, not a standard J-hook. Always verify the packaging explicitly states compatibility with Ford Super Duty trucks.
Swapping Driver and Passenger Sides
Installing the 26-inch blade on the passenger side creates a high risk of wiper clash. The longer blade will overlap the driver’s path, causing the arms to hit each other. Always match the 26-inch blade to the driver side and the 18-inch to the passenger side.
Trying to Cover the Center Gap
You will notice a small triangular area in the center of the windshield that the wipers do not cover. This is a normal design feature of the F-350. Do not attempt to fix this by installing longer blades, as it will cause mechanical failure.
Tips for Extending Wiper Life
Maximize the performance of your new blades with these maintenance strategies. Proper care extends the life of your wipers and protects your windshield.
Replace Blades in Pairs
Always replace both wiper blades at the same time, even if one looks better than the other. Old rubber hardens and cracks, leading to uneven wiping patterns. Fresh pairs ensure balanced pressure and a streak-free view.
Clean the Windshield Regularly
Road film, tree sap, and dirt accelerate rubber wear on your wiper edges. Clean your windshield monthly with a dedicated automotive glass cleaner and a microfiber cloth. A clean surface reduces friction and helps blades last longer.
Inspect Wiper Arms for Damage
Check your wiper arms for bends, corrosion, or weak tension. If an arm does not sit flush against the glass, it creates streaks regardless of blade quality. Replace bent arms immediately to maintain proper contact.
Signs It Is Time to Replace Wipers
Knowing when to change your blades is just as important as knowing the correct size. Watch for these indicators that your current wipers have failed.
Visual and Performance Warnings
- Persistent streaking or smearing across the glass
- Chattering, skipping, or squeaking noises
- Unclean patches remaining after a wipe cycle
- Visible cracks, splits, or missing chunks in the rubber
- Bent metal frames or exposed structural elements
Recommended Replacement Schedule
Ford recommends replacing wiper blades every 6 to 12 months. Vehicles parked outdoors or driven frequently in harsh conditions may need annual replacement. Proactive changes prevent sudden failure during a storm.
Frequently Asked Questions About 2017 F350 Wipers
Can I use a 24-inch blade on the driver side?
While a 24-inch blade might fit physically, it leaves a significant portion of the driver’s view uncovered. Stick to the factory 2017 f350 wiper blade size of 26 inches for maximum safety and coverage.
Do all 2017 F350 trims use the same wiper sizes?
Yes, all cab configurations including Regular, SuperCab, and Crew Cab use the same 26-inch and 18-inch front wiper sizes. The only variation is the potential absence of a rear wiper on most models.
How do I know if my wiper adapter is correct?
The 2017 F-350 uses a pin-style or stud-mount adapter, not a standard J-hook. Check the packaging for “Ford Super Duty” compatibility or visually compare the connector to your current wiper arm before buying.
Why do my new wipers still streak?
Streaking often results from a dirty windshield or improper installation rather than defective blades. Clean the glass thoroughly and ensure the blade is locked in at the correct angle. If streaking persists, the wiper arm tension may be too low.
Are beam blades better than conventional blades for trucks?
Beam blades generally perform better on trucks due to their aerodynamic design and resistance to ice buildup. They provide more consistent pressure on the large, flat surfaces of the F-350 windshield compared to traditional framed blades.
Key Takeaways for 2017 F350 Wiper Maintenance
