Good product but not 100% correct
The product was high quality but unfortunently this did not work for all 4 sensors as the connectors were different. This is not 1As auto fault as Chevy trucks some have the flat connector on the pre cats and some have the square. Before purchasing this verify what you have.

Wrong part for truck
Complete wrong oxygen sensors for my truck, even though the listing said "guaranteed to fit". I found that out too late after I had already opened them. Going to try to salvage some of the cost by listing the new ncorrect parts on eBay. I don't know what these fit, but it wasn't my truck.
