The front wiper blades are 24 inches on the driver’s side and 18 inches on the passenger side; there is typically no rear wiper on the 2020 Challenger.
Wiper sizes can vary by market and trim. The sizes below reflect the common specification for U.S.-market Challengers and most trims, but you should verify against your owner’s manual or the blade you purchase if in doubt.
Front wiper blade sizes
Before listing the sizes, note that the Challenger uses distinct sizes for the two front blades.
- Driver-side blade: 24 inches
- Passenger-side blade: 18 inches
These sizes apply to the factory equipment and typical aftermarket replacements. If your Challenger is a special export version, double-check the exact lengths with the manual or dealer.
Rear wiper and maintenance notes
The 2020 Dodge Challenger sold in North America generally does not come with a rear windshield wiper. If you have an aftermarket rear wiper or a market variant that includes one, consult the owner's manual for the correct blade size and installation instructions. Regular replacement and proper blade choice help maintain visibility in all weather conditions.
Summary
Bottom line: For a typical 2020 Challenger in the U.S., use 24-inch driver-side and 18-inch passenger-side front wiper blades; there is usually no rear wiper. Always verify with your manual or dealer if you’re unsure.
