Front rotor size

[FloridaBoy]

Hey all need to know what is the rotor size on a 2005 V8 size 17 inch rims. Is it a 13.30 or 12.6. Please help.

Early on it was only the Sport Edition that had 13.3 but I have them on my 05 V8 LE.

It's not hard to pull the wheel and measure. Kind of hard to be real precise but with a .7 inch difference between the two it's easy make a determination. There are probably better ways but you can lock a tape and set it on the ground so the top of the tape is level with the top of the rotor, then get eye level with the bottom of the rotor to get a reading.

Limited ? SR5? Sport? What model truck do you have?

Its super rare that a non-Sport model truck had the 13.3 rotors.

If you have a Limited or SR5 I'd wager you have the 12.6 ones.

Do these two different sizes require different caliper / pads ?

13wh calipers take the bigger rotors

That's how I determined that my Limited has the bigger rotors. I used a bubble level to eliminate any tilt in the level that might give a false reading/reference point.
