Below are the configurations you’re most likely to encounter.
Here are the blade lengths you’re most likely to encounter on Ram 2500 pickups, by era and configuration:

How to confirm the exact size for your Ram 2500
To ensure you purchase the correct blades, use these verification methods before buying:
- Check the owner’s manual or the vehicle’s window sticker for the recommended blade lengths on each side.
- Inspect any labels under the hood near the wiper linkage area; many Ram models print the driver and passenger blade sizes there.
- Measure the current blades if you can access them: measure tip-to-tip for both sides or note the blade part numbers stamped on the blades themselves.
- Use a VIN-based parts lookup through a dealer, Mopar, or reputable parts retailer to pull the exact blade sizes for your specific configuration.
With the exact size confirmed, you can confidently purchase the correct wiper blades, ensuring proper fit and performance.
Summary
The Ram 2500 does not have a universal front wiper blade size. While 24-inch driver-side and 18-inch passenger-side blades are common across many years, variations exist by model year and market. Always verify using the owner’s manual, under-hood labels, current blade measurements, or a VIN-based parts lookup to ensure an exact match.
