So my truck failed the emissions test and my shop says it's probably the cats. My truck has under 60k miles on it. Isn't that kinda quick for the cats to wear out? Can the o2 sensors go bad and not trigger the idiot lights?

I could be wrong but my understanding is that the age of a cat doesn't determine when they go bad. Running rich or lean will cause it to go bad... otherwise, mileage or physical damage to the cat's shell will also cause it to go bad.

If you have a 97, get the ODB read... is it throwing a code or did it fail the sniffer? Is "your shop" the same place that did the smog? The smog testers will have info on exactly why you failed.

Failed sniffer. Obd is clear. I will double check with shop to see what I failed on.

I've heard that coolant can also kill the cat. So if you have a head gasket leak, that'll do it. However when that happens, the exhaust becomes clogged (so I've heard from my mechanic).

You don't have any codes or check engine lights or anything like that?

as mentioned age and mileage do not determine failure.
what gases caused it to fail?

How long was the engine running before it was put up to the sensors? Drive around for a bit then while waiting run the engine at 2000 rpms for a couple and they should be nice and hot and then pass the emissions. How much do you drive your truck on a daily basis?

Provide your HC and CO readings. This will help in determining where to look.

I've also been told that changing your oil and filter before going in for the test will help. The logic is that there is gasoline in the oil (blow by) and this affects the test results.

Do like another has suggested, get the engine nice and hot before you go in for the test.

Bc is pretty stringent... Close if not equal to Cali standards...

It's the NO that is over by .3

Tried again with a set of used cats and it was better but still failed (.3 is from second reading)... Had oil change less then 200 Kim's ago... And it was hot...

Cats and oil have no effect on NO.
