Great o2 sensor set.
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.
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.

Better then tool brands trucks
I highly recommend this My co worker but a cornwell set And I bought these Compared them and tested them on a seized up inlet nox and gear wrench did not slip in fact took it right out like no tommorow Compared to the cornwell set which slipped it and round it out a bit even tho it damaged it but gear wrench still over took it and I am amazed by the price for the quality and strength they have well worth trusting it for the price

Waiting to use them
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!
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!

Typical Gearwrench with good build quality. Nice storage case. Good to have in the tool arsenal.

quality, value, trusted brand,
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.

Essential for modern cars
This is a fairly oddball set compared to normal sockets. Impact safe these are good sockets that make it much easier to get O2 sensors out of cars.

Great Set
My oil pressure sensor went on my 2007 Chevrolet Avalanche and was looking to replace it and need a special socket to replace it. I was looking to buy just the socket for the oil pressure sensor but for the price of just the socket itself you are almost close to buying an entire kit. I was also looking to replace my 02 sensors in my truck so I thought buying the entire kit is the best option and most affordable. When I was looking at this kit, I couldn’t find what size of the sockets that the kit came with so I had to go the Gear Wrench website of find out. If anyone else is wondering what the kit comes with, I listed it below: - 1/2’’ Drive Oil Sensor Socket 1-3/16’’ (29mm) - 3/8’’Drive Slotted Socket for PVS, TVS. & 02 Socket (7/8”) - 1/2’’ Drive Thermal Sensor Socket 1-1/16’’ - 3/8 Drive Oxygen Sensor Socket 7/8’’ (22mm) - 3/8’’ Drive Deep Oil Pressure Sending Socket 1-1/16’’ - 1/2’’ Drive Oxygen Sensor Socket 7/8’’ (22mm) - 3/8’’ Drive Low Profile Offset Oxygen Sensor Socket 7/8’’ (22mm) Now you are only going to see at 7 different sockets listed and the kit comes with 8, I really didn’t understand because the picture shows 8 sockets but I didn’t know what the 8th socket was until it arrived. It was a mystery and didn’t know what they didn’t list it. When did it arrive, I immediately used the oil pressure sensor for my truck which worked perfectly. Now after going through the sockets the 8th socket is: - 3/8’’ Drive Short Access Socket 1-1/16’’ (For Some Chrysler Vehicles) Conclusion, I would say all the sockets are high quality and work well for the application. I would say for the price the set it great because it contains a common sockets for different applications. The case is great because everything stores nicely and is blow molded in case it’s dropped. I would recommend this to anyone!
