The front wipers on a Jeep Wrangler JK are typically 22 inches on the driver’s side and 21 inches on the passenger side, while the rear wiper, if your model has one, is usually about 12 inches. For accuracy, always verify against your specific year and body style (2-door vs. 4-door) and check the current blades or owner’s manual.
The Jeep Wrangler JK, produced from 2007 to 2018, uses standard front blade sizes for most models, with a rear blade size that applies to the four-door Unlimited version. Replacement choices include OEM blades or high-quality aftermarket equivalents. Always confirm fitment for your exact vehicle configuration before purchasing.
Front wiper blade sizes (Jeep JK)
These are the typical front blade lengths for the JK’s two-front-wiper setup. Some aftermarket options may offer different styles, but the lengths above are the most common for stock and many aftermarket replacements.
- Driver-side blade: 22 inches
- Passenger-side blade: 21 inches
Using the correct front blade lengths helps ensure full coverage of the windshield and prevents streaking. If you replace blades with a different length, check for proper clearance and sweep pattern compatibility with your windshield and wiper arms.
Rear wiper blade size (Jeep JK)
Note: The rear wiper is only present on many four-door JK Unlimited models. If your Jeep does not have a rear window wiper, this section does not apply.
- Rear blade: 12 inches (if your model includes a rear wiper)
When replacing the rear blade, ensure you are selecting a blade designed for the JK’s rear window mounting and connector type. Some aftermarket blades come with adapters to fit the stock arm.
Additional considerations
Beyond the basic lengths, you’ll want to choose the blade type and installation method that best suits your climate and driving conditions. Forecasters of rain, snow, and dust may benefit from beam-style blades, which maintain consistent contact across the windshield, while conventional frames can be easier to replace and more affordable.
Blade types
Beam (or hybrid) blades offer better performance in some weather conditions due to continuous pressure distribution, whereas traditional framed blades can be compatible with a wide range of arms. Check compatibility with your Jeep’s wiper arm adapters when shopping.
How to verify size on your Jeep JK
If you’re unsure, measure the current blade length by extending the blade and measuring from the joint where the blade attaches to the arm to the far end of the blade. You can also consult your owner's manual or an online parts lookup using your VIN or year/model. When in doubt, bring the old blade to the store to compare lengths.
Summary
For a Jeep Wrangler JK (2007–2018), plan for front wipers of 22 inches on the driver’s side and 21 inches on the passenger side, with a rear wiper blade of about 12 inches if your model has one (primarily the 4-door Unlimited). Always confirm fitment for your exact vehicle configuration and consider blade type based on climate and maintenance preferences. Replacing blades in pairs for the front and selecting the correct size for the rear will help maintain clear visibility and optimal performance.
