This fit my drivers side with a very slightly different angle. Not so much that I would care at all. The entire sweep of the entire wiper now remains on the glass.Before I purchased this, I thought I was getting deformed wipers that didn’t sweep the rain from the middle of the wiper. After switching brands of wipers, I still had this problem. Then it occurred to me that the 20 year old springs in the OEM wiper arms had lost strength. This replacement solved my problem!

was ship 2 days late end doesen’t fit the car
Larry Fitch –
Arm fit and was easy to install, I did bend the metal arm that wiper blade attaches to for a perfect fit. It would have worked fine without bending the arm. Price was right, compared to more expensive arms that were twice the price.

Works good looks good wipes the whole windsheild now instead of leaving a big spot of water on 1/3 of it. If you’re worried about fading paint spray some clear coat over it before you put it on

My Ford F450 Super Duty is my Bread and Butter. Without it I make no money and do not get any work done. The wipers were missing a 4 inch thick swath right in front of my face when driving in the Rain / Snow etc. No problem, I’ll just get new wiper blades right? Wrong, That didn’t work. It turns out that the springs inside the wiper arm are what holds the wiper up against the windshield, putting pressure as it wipes away the rain. When the springs get weak, the pressure decreases allowing the wiper blade to lose contact with the windshield surface in places. Some people try to bend the wiper arm to fix the problem. That is STUPID and DANGEROUS. Buy new Wiper arms and fix the problem correctly. These work GREAT and I can see clearly when the weather is Bad. Great Product – Works like it should !
