Yes, that is correct. And if you have all the added weight on your truck all the time, then they would recommend the HD rear springs to help get your lost ride height back.
How in the world are you guys getting decent MPGs? I have BFG 35s, I average 14.5-15 in town, easy on the gas pedal, and hwy (@75-80MPH) I might see 16, I do get better if going 65, I can see 18 MPGs at that speed. I did notice a huge drop in mileage when I went from the GY tires to these...
I know this, but you replied asking if I was looking for the "E" version, but in my question above that you replied to, I was asking for the non HD rear springs part number without having to buying the "kit", and so my answer to your question was no, that is not the part number for the rear only...
No, the non HD versions is F31-35-056-01-RA, I ordered from Eibach directly by calling. ($99 plus shipping)
Here is my write up on my lift. Just scroll further down and I have before and after pics along with measurements of the before and after lift...
I repaced my rear HOSS 3.0 springs to Eibach since the rear would sag so much with added weight. At first the rear was a bit stiffer and I was a bit bummed on the ride, especially when I went over a speed bump, but after roughly 2500 miles of driving, the Eibach spring broke in and I can fly...
Oh wow, I didn't know that, well, now I know lol.
Yeah, more than likely, like you said, you will have to reapply a 3M trim panel adhesive backing to the removed lights to install in a new slot location. Then you will have to clean the old adhesive that may have stayed behind on the grille...
Simply uninstall two lights and reinstall into a different slot. I wouldn't think it's that difficult. Not sure how these ones are installed, but I would assume pretty simple to remove and replace if needed.
