    • Great o2 sensor set.
Size: (Pack of 1)
You just can't go wrong with gearwrench. If you work in the industry professionally these are great. They have lasted me 6 years so far working in a dealership. Durability/Quality is great and the fact they come in a case that you can store in your box is also amazing. Overall highly recommend them.

    • Nice thickness, no sharp or rough edges, lifetime warranty.
Size: (Pack of 1)
Before purchasing I saw some reviews complaining that the set was made from CR-V. Why? These aren't impact rated sockets. CR-V is actually a harder and more expensive than CR-Mo and is the ideal material for non-impact sockets like these. The largest of the sockets is CR-Mo and would likely hold up to impact use, but again, these aren't impact rated sockets. Please at least have a basic understanding of what you're buying before complaining. These are solid. While these are one of those items that the average home user is going to use infrequently, you never know when you'll need them. I compared the GM oil pressure sending socket to a comparable one from Lisle and the quality was MUCH better. The Lisle socket is functional, but has rough and sharp edges inside. The Gearwrench socket is very well made and was actually cheaper when you factor in price-per-socket. The lifetime warranty helps give peace of mind. I'm overall very happy with these. If I have a longevity issue I'll update my review. ... show more

4 stars only due to not using them yet. The came with a film of oil to protect them from rust. The blow molded case is sturdy. GW makes good stuff I'm sure these will work as they should when I need them.

    • Great Value for the Money!
Size: (Pack of 1)
With the variety of Sensor Sockets in this kit your vehicle it should cover many of the Sensor fitments you will run into on vehicles today. Makes short work of removing and installing a faulty sensor. much easier than trying to use a wrench that is not intended for a sensor with a wire attached. It fits the sensor so there is no worry of rounding off the flats and making a nightmare out of what can be a quick and easy job! ... show more

    • quality, value, trusted brand,
Size: (Pack of 1)
Nice complete set. For the price I paid, it’s a five star value considering lifetime warranty. It’s about 4 Star quality. All the sockets are CrV except the biggest which is Chrome Moly. Would have preferred all Chrome Moly. One of the openings/grooves cut into a socket wasn’t finished well. Had a sharp metal burr I had to grind off. Another socket opening for your ratchet anvil was functionally fine but showed some marks. While you can get an identical set elsewhere, it’s not lifetime warranty. On sockets like these that can break, GearWrench is absolutely worth it. Best deal I’ve found for the complete set which will cover most applications on just about any make and model from the past 20 years or so. ... show more
