I have a 2001 Suburban 1500 LT w/ 5.3L motor and LSD. How do I find out which diameter rear rotors I need? There is more than one size.

count the # of wheel lugs

6

or

8

that'll give the parts counter guy the proper rotor for the rears...

I'm ordering them online. According to the website there are 13" and 12" both with 6 lugs.

Thanks. I took them off already. Thought I might find someone who knew the difference here.

If you vehicle is 7200 lb GVWR then they would use the 12 13/16" rotors

If it is the 9000 GVWR then you need the 13" rotors.

As mentioned though, seeing how you have them off, measure the diameter to be sure.
