One important but often overlooked maintenance task is replacing your windshield wiper blades regularly.

Worn out or incorrectly sized wiper blades can significantly reduce visibility and your safety in poor weather conditions. So you’ll want to know the precise factory wiper blade sizes for your 2018 Wrangler, and how to find perfect replacement blades when it’s time.

In this comprehensive guide, we’ll answer the key question:

What are the correct wiper blade sizes for a 2018 Jeep Wrangler, including driver’s side, passenger side, and rear wiper lengths?

The short answer is:

• Driver’s side blade length: 28 inches
• Passenger side blade length: 24 inches
• Rear wiper blade length: 19 inches

Below, we’ll go into greater detail on exactly why having properly sized wiper blades matters, how to find the right replacement blades for your 2018 Jeep Wrangler, step-by-step blade replacement instructions, and tips on prolonging the life of your new wipers. Let’s dive in!

Why Does Wiper Blade Size Matter on Your 2018 Jeep Wrangler?

Beyond just keeping your windshield clear of rain, snow and debris, your wipers play a crucial role in safety. According to the Bureau of Transportation Statistics, over 1.7 million vehicle crashes per year in the United States occur in inclement weather. Having wiper blades that are precisely matched to the curvature and surface area of your Wrangler’s windshield ensures maximum contact and clearing capability.

Conversely, incorrectly sized wiper blades can lead to a few frustrating problems:

• Streaking and smearing – blades don’t fully contact the windshield, leaving unwiped areas that reduce visibility.
• Chattering and squeaking – misaligned blades cause skip and drag on the windshield as you drive.
• Poor cleaning performance – blades don’t clear water, snow or debris effectively from the windshield.

The factory equipped wiper blades on your new 2018 Jeep Wrangler are engineered specifically for each placement on the windshield to provide flawless wiping and visibility. Using this same OEM sizing when replacing your blades ensures you get that same level of windshield contact and wiping performance.

What Are the Wiper Blade Sizes on a 2018 Jeep Wrangler?

Now that you know why using the proper OEM blade lengths matters, let’s look at exactly what those sizes are for the 2018 Jeep Wrangler:

Driver’s Side Blade Size

The driver’s side windshield wiper blade on all 2018 Jeep Wrangler models measures 28 inches long. This provides full edge-to-edge clearing coverage on the driver’s side of the windshield.

Passenger Side Blade Size

The wiper blade length on the passenger side of a 2018 Jeep Wrangler is 24 inches long. The passenger side blade is a few inches shorter than the driver’s to match the slightly smaller windshield area on that side.

Rear Wiper Blade Size

Finally, the rear wiper blade on the 2018 Wrangler measures 19 inches long. This rear wiper clears the back window for improved visibility when backing up in rainy or muddy conditions.

Knowing these precise lengths for each blade is invaluable when searching for direct replacement wiper blades for your 2018 Jeep. Let’s look at how to find perfectly matched blades using just your model year and wiper sizes.

Finding the Right Replacement Wiper Blades

When those factory blades eventually wear out or streak, replacing them with equivalent models ensures your Wrangler’s windshield remains crystal clear and safe in all conditions. Here are some tips for finding properly sized replacement blades:

• Search by vehicle year and model – Many online stores like Amazon allow you to input your 2018 Jeep Wrangler’s year and model to show guaranteed fit replacements. This takes any guesswork out of finding the right part numbers.
• Search by blade lengths – Alternatively, you can search directly by “28 inch wiper blade”, “24 inch wiper blade”, etc. to pull up blades of the exact length needed. Brands like PIAA list the lengths right in the product names too.
• Stick with premium brands – For optimal wiping, go with top rated blades from trusted manufacturers like Bosch, Anco, or PIAA. You’ll pay slightly more but get a more durable blade with superior wiping performance.
• Avoid cheap no-name knockoffs – Many low cost universal fit blades may claim to fit but don’t actually contour properly to your Wrangler’s windshield. Stick with major brands designed specifically for your vehicle.
• Check connections – Ensure any replacement blades have the correct attachment type and size to snap securely onto your 2018 Jeep’s wiper arms. You usually want a universal adapter for easy install.

Taking a few quick measurements of your existing blades or simply inputting your Wrangler’s details during your search makes it easy to order up the right replacement wiper blades every time. Next let’s go over how to actually replace the blades on your Jeep.

Step-by-Step Guide to Replacing Wiper Blades

Once you’ve purchased replacement blades for your 2018 Jeep Wrangler, swapping them out is a quick and simple job you can tackle right in your own driveway. Here is a step-by-step DIY guide to safely removing the old blades and installing your new ones:

Gather Tools and Supplies

You’ll need a few basic items:

• New replacement wiper blades (for driver’s side, passenger side, rear wiper)
• Clean rag or paper towel
• Isopropyl alcohol cleaning solution

Lift Wiper Arm Off Windshield

• Turn wipers to the off position before raising blades off windshield.
• Gently lift the wiper arm to raise the entire blade off the glass.

Locate Release Tab

• Look for a small tab somewhere along the wiper blade housing.
• This tab must be depressed to detach blade from the arm.

Depress Tab and Slide Out Old Blade

• Press and hold tab while carefully sliding the wiper blade down toward the base of the arm.
• The entire blade housing will detach from the arm.

Align and Insert New Wiper Blade

• Take your new replacement blade and orient it to slide into the now empty wiper arm.
• There may be ridges or notches to align the blade housing properly.
• Slide the blade fully upwards into the arm until it clicks into place.

Test New Blade Fitment

• Lower reattached wiper arm and blade back onto windshield.
• Turn wipers on to ensure new blade makes full, consistent contact across entire windshield.
• Repeat steps for installing remaining new blades on other arms.

And that’s all there is to it! In less than 30 minutes you can install fresh, perfectly sized wipers on your Jeep Wrangler for crystal clear visibility once again. Just be sure to dispose of old blades properly.

Why It’s Important to Replace Worn Out Wipers?

Putting new blades on your 2018 Jeep Wrangler before the existing ones are fully worn out has some big benefits for performance and safety. Here are key reasons you’ll want to swap in new wipers regularly:

• Prevent streaking and smearing – Fresh rubber blades glide smoothly over the windshield without skipping or dragging. Old blades lose contact with glass.
• Maintain better wiping capability – Worn blades won’t clear water as effectively. New ones easily sweep moisture from the windshield.
• Avoid cracked rubber tearing – Blades become brittle and can tear over time. Tiny tears spread and obstruct visibility.
• Retain friction for ice/snow clearing – Worn rubber loses grip needed to scrape frozen precipitation from windshield.
• Maintain windshield coating – Cracked blades can scratch glass over time, damaging UV or rain repellent coatings.

For optimal visibility and safe driving, be sure to inspect blades every few months and replace any that are worn, damaged or streaking across your line of sight.

Extend Wiper Blade Life with Proper Care

Your wiper blades work hard keeping your view unobstructed in all sorts of conditions. Taking good care of them ensures they last their full lifespan. Here are some tips for maintaining your 2018 Jeep Wrangler’s wiper blades:

• Regular cleaning – Wipe blades and windshield down regularly with isopropyl alcohol solution to remove dirt buildup.
• Avoid using blades to clear ice – Scraping frozen windshields damages rubber. Defrost first or use deicer spray.
• Check and replace worn blades – Inspect for cracks or fraying every 6-12 months and replace sooner if needed.
• Flip blades up when not in use – This takes tension off the rubber and prolongs blade life in hot climates.
• Park out of the sun – Avoid prolonged sun exposure which can bake and dry out rubber blades prematurely.
• Top off wiper fluid – Keep fluid reservoir full to prevent blades from smearing dust and dirt on dry windshield.

With proper care and regular replacement of worn blades, you can enjoy crystal clear visibility through your Wrangler’s windshield for years of fun open air Jeep driving.
