I'm going to need new rotors soon and am confused by the specs I'm finding. There are apparently two rotor sizes:

1.) 11.61" diameter with a 1.04" thickness, and a height of 4.19"

2.) 11.63" diameter with a 1.29" thickness, and a height of 4.55"

I'm particularly confused by the "height" spec.

I would rather not disassemble everything to measure what I currently have installed when there may be a logical answer based on the VIN number, or something. Also, it could be the previous owner installed the incorrect size at some point and I'd like not to repeat his mistake.

Any thoughts?

Thanks!

probably depends on VIN number, could be different for a tow package, etc. i know with my 05 its a pain to get brake parts, my truck has some Frankensteined parts from the factory, some HD some 1500..i would verify with the dealership what part number you need first
