Hd or normal duty?

[bambam78]

Went to replace my rotors and brakes today and i had two options the heavy duty option and the light duty option, my trucks a 91 rclb 4x4 1/2ton, just wondering if it would matter which rotors i went with, or how you could tell its a hd? thanks

If it's a 1/2 ton then it's not HD.
