2020 Subaru Crosstrek — Wiper Blade Sizes

Quick reference

Best aftermarket replacements

• Bosch ICON (premium, $$$): Front 26" driver and 16" passenger. Excellent longevity and all-weather performance. For the rear, use a 12" rear-specific Bosch blade.
• Rain-X Latitude/Latitude Water Repellency (upper mid-range, $$): Front 26" and 16". Leaves a hydrophobic coating. Matching 12" rear available in their rear line.
• Trico Force/Trico Titan (mid-range, $$): Front 26" and 16" beam blades with wind spoiler. Trico Exact Fit/Rear line covers the 12" rear.
• Michelin Stealth Ultra (mid-range, $$/$$$): Hybrid front blades in 26" and 16" provide good windshield contact. Pair with a 12" Michelin rear blade.
• PIAA Si-Tech (premium, $$$): 26" and 16" silicone beam blades for the front; silicone refill tech resists UV. Use a brand-matched 12" rear blade where available.

Tip: Many front beam blades ship with multi-adapters that fit Subaru’s push-button top-lock arms. Verify the package lists “Top Lock/Push-Button (19mm)” compatibility. Rear blades are vehicle-specific; choose one listed for the 2020 Crosstrek.

Attachment style

Most 2020 Subaru Crosstrek front wiper arms use a push-button “top lock” connection (often referred to as Top Lock 19mm). This differs from the older J-hook style. You’ll find a small release button on the upper side of the blade where it meets the arm. The rear uses a model-specific rear arm with a small push-tab/integrated connector—use a rear blade made for the Crosstrek.

Common attachment types you might see across vehicles include:

• J-hook
• Side pin
• Bayonet
• Push-button (top lock)

For this model, expect push-button (top lock) up front and a dedicated rear connector in back.

How to install

1. Protect the glass: Lift the wiper arm and place a towel on the windshield in case the arm snaps back.
2. Remove the old blade (front): Press the small release button on the top-lock connector and slide the blade toward the arm tip to disengage.
3. Fit the adapter (if needed): Choose the “Top Lock/Push-Button” adapter included with your new blade and snap it onto the blade body.
4. Attach the new blade: Align the adapter with the arm’s top-lock channel and push until it clicks. Tug gently to confirm it’s locked.
5. Rear blade: Lift the rear arm, press the tiny tab on the hinge-side of the blade, and slide it off. Install the new 12" rear blade in reverse until it clicks.
6. Test: Lower arms carefully, then run the washers to confirm quiet, streak-free operation.

Note: If your blade/arm uses an unusual adapter, refer to the instructions included with the blades—manufacturers include clear diagrams for each connector style.

When to replace

• Time: Every 6–12 months is typical, sooner in extreme heat/cold or heavy use.
• Symptoms: Streaking, chattering, squeaking, missed patches, or cracked/ragged rubber edges.
• Visibility: If rain performance worsens or the blades leave haze, replace promptly for safety.
