Hey everyone, Haven't been on here in awhile, which i guess is good as it means, i've had no problems with my truck. I want to replace the front and rear rotors this summer. They list 3 different rotor options for the rear rotors on my truck. Which one will fit my truck (2003 Silverado 1500 w/ 4.8L) Nothing HD that i know of. They list the following options.

1) 325MM X 85MM
2) 330MM X 95MM
3) 330MM X 96MM

how would i know which one to get? Thanx, Jim

 

your best bet is to measure the diameter of the center of your rotor and multiply your measurement by 3.14
85 millimeters = 3.34645669 inches
95 millimeters = 3.74015748 inches
96 millimeters = 3.77952756 inches
