🔧 GearWrench KDS3925 3/8" Drive Low Profile Offset Oxygen Sensor Socket 7/8" (22mm) - 3925D Black - Enhanced SEO Review

Due to a 25 year old O2 sensor, this tool bent and did not remove the part. But you can't blame the tool for that. Overall the quality seems good for the price and I am keeping this tool for use on other not so neglected vehicles.

Worked great for installing new sensors, when removed after a few years they broke in half and almost gouged my eye out. I've never used a percussion gun with it, but used a regular brake rod (about 18 inches). I estimate I was about 125 ft/lbs when it broke.

A simple tool for easy oxygen sensor removal. Our Trailblazer is from 2006 and the original sensor was easy to remove with this tool. I sprayed some penetrating oil on the threads the night before and the sensor unscrewed with minimal effort.

This connector will save you a headache if you're changing the sensors yourself, just make sure you have a blowtorch handy. Sure, you could just cut the wire and use a regular wrench, but attaching an extended breaker might work better if you have the space.

The 3ft rod didn't do the trick but a few good hammer hits and then the breaker rod got it done in a short time. The tool withstood hits with hammer and crowbar masterfully, did not round or wear out.
