JB3 vs JB5

[mrnapolean1]

Whats the difference between JB3 and JB5?

Im needing front rotors and autozone calls for two different kinds: JB3 and JB5.

IIRC, the difference is the thickness of the rotors. JB5 is .25 thicker to the best of my knowledge. As far as diameter, I think they are the same and also use the same pads.

Maybe someone else can confirm.

For purpose of getting parts, you should be able to measure the diameter of the rotor and the thickness. Of course the thickness could be off a bit due to being turned, but you should still be able to figure out if you have a 1 in or 1.25 in thick rotor.
