So question for you F250 7.3 Tremor guys. That article says the F250 7.3 Tremor has the smaller spring pack. Every video I've seen shows otherwise and that "every" F250 7.3 Tremor has the same heavy duty spring pack. Can you F250 7.3 Tremor guys confirm? Here is a video for reference that shows an F250 7.3 Tremor with the heavy duty pack. Also, when you try to build a package on ford's website, it wont let you build a F250 7.3 and select the camper or snow plow package or even the high capacity package. This is probably because the Gas Tremor comes standard with the heavy duty rear spring pack. Maybe the author of that article is just misinformed.... or maybe I am!
