RigidWire Windshield Wiper Arm Pair for Ford Super Duty & Excursion 1999-2007 - Direct OEM Fit, Corrosion-Resistant

If your Super Duty or Excursion wiper arms are bent, corroded, or no longer hold the blade securely against the glass, this RigidWire replacement pair provides a precise fit and durable construction engineered to match the original factory geometry. These arms are designed to reconnect your existing wiper blades and pivot hardware without modification, giving even pressure and steady motion across the windshield so visibility improves in rain, sleet, and light snow.

Will these wiper arms fit my Ford Super Duty or Excursion?

Yes — these parts are specifically manufactured to match the factory fit for many Ford trucks and SUVs from the listed years. They are intended as direct replacements for OEM reference numbers, so installation uses the original mounting points and hardware.

• Compatible models: Ford F250, F350, F450, F550 Super Duty (1999–2007) and Ford Excursion (2000–2005).
• Direct-replacement part numbers: 42647 & 42648 replacing F81Z17527AA and F81Z17526AA.
• No drilling, trimming, or special adapters required — mounts to original pivot studs.

How does the RigidWire arm improve wiping performance?

The arm's geometry and firm mounting restore the blade's intended contact across the windshield, which reduces streaking and chatter. A consistent, even downforce helps the blade clear water and debris more effectively at different speeds.

• Engineered to maintain OEM blade angle and pressure distribution across the glass.
• Stable motion prevents skipping and reduces wind lift at highway speeds.
• Works with your original wiper blades — change blades without replacing arms.

What are these arms made of and how long will they last?

RigidWire builds these arms from corrosion-resistant, high-strength materials to withstand road salt, moisture, and daily use. The materials and finish slow rusting and help preserve the accurate shape and spring tension so the arms stay functional for many seasons.

• Durable metal alloy with protective coating for corrosion resistance.
• Robust construction resists bending and fatigue from repeated use.
• Designed to retain OEM pivot alignment for long-term reliability.

How difficult is installation and what should I check before buying?

Installation is straightforward for anyone comfortable with basic hand tools: remove the old arm from the wiper pivot, position the replacement, and secure the retaining nut. Confirm year, model, and which side (driver/passenger) if applicable to ensure exact fitment prior to purchase.

• Typical installation time: 10–20 minutes per arm with common tools.
• Verify vehicle year and OEM part numbers (F81Z17527AA / F81Z17526AA).
• Keep original blade assemblies or replace blades after arm installation for best results.
