Perfect Fit and Great Performance
Size: 15"+15"+13"
These 5 PLUS wipers fit my Wrangler JK perfectly and were super easy to install. The front and rear blades wipe clean with no streaks, even in heavy rain. They feel just like OEM quality but cost a lot less. Great value for a full 3‑blade set. Highly recommend for any 2007–2018 JK owner.

Excellent replacement blades
Size: 26"+16"+14"(B)
Fit my 2023 Mazda CX-30 perfectly. Challenging removing the original Mazda front blades. Very easy installing these new blades. I had to remove the rear wiper arm to install the new rear blade. first, lift the cover at the wiper arm pivot point to access the fastening nut. Loosen and remove the nut and washer with a 13mm socket. Replace the wiper and fasten the wiper arm with the original washer and 13mm nut. Snap down the pivot cover. The new blades operate quietly and thoroughly remove water from the front and rear windows.
