Quick reference

Best aftermarket replacements

These lines fit the 2018 Ram 3500 using the common J-hook (9x3) connector. Order two 22-inch blades for the windshield.

• Bosch ICON: Premium beam blade; excellent all-weather performance and longevity. Typical price: $25–35 each.
• Rain-X Latitude (or Latitude Water Repellency): Popular mid/premium beam blade with built-in water repellent on some versions. Typical price: $18–30 each.
• Trico Force (or Trico Ultra/Trico Titan): Aerodynamic beam options that perform well at highway speeds. Typical price: $20–30 each.

• PIAA Si-Tech: Silicone beam blade that lays down a water-repellent layer; long service life. Typical price: $30–40 each.

Tip: Choose the package variant that lists “J-hook” or “9x3 hook” compatibility. Many blades include multiple adapters—use the standard hook adapter for this truck.

Attachment style

• Primary: J-hook (9x3). This is the traditional curved hook on the end of the wiper arm found on most Ram HD trucks of this generation.
• Less common: Some aftermarket arms use different adapters (side pin, bayonet, push-button). If your arm does not have a curved hook, match the arm style to the adapter included with the blade or consult your parts counter.

How to install

1. Protect the glass: Lift the wiper arm away from the windshield. Place a towel on the glass in case the arm snaps back.
2. Release the old blade: On a J-hook arm, press the small tab where the blade meets the arm and slide the blade downward to unhook it. Then pull it off the arm.
3. Prep the new blade: Select the J-hook adapter if the blade includes multiple adapters. Confirm the blade length (22 in).
4. Attach: Slide the hook through the blade’s opening, then pull upward until it clicks/locks into place. Tug gently to verify it’s secure.
5. Repeat for the passenger side and lower the arms carefully.
6. Test: Spray washer fluid and run the wipers to ensure smooth, quiet operation and full sweep coverage.

Note: If your arm uses a side pin, bayonet, or push-button style, follow the brand’s included adapter instructions—steps differ slightly for the locking clip or button release.

When to replace

• Interval: Every 6–12 months is typical. Replace sooner in harsh climates or if the truck sits outside.
• Signs it’s time: Streaking or haze, chattering/skipping, squeaking, split or jagged rubber edges, missed spots, or poor performance in rain/snow.
• Pro tip: Clean the rubber with a damp paper towel and mild glass cleaner during fuel stops to extend life. Replace as a pair to maintain even performance.
