Well I'm glad its helping some... I kept my bags isolated. Here's why: As much as I try to load the truck evenly, it doesn't always happen, esp with the fridge on one side. Isolated, I can get it perfectly level, side to side. I can see the argument with a solid rear axle, so you can get flex by stuffing one bag (inside the coil) and stretching out the flexed out side. With an indy rear, this doesn't happen right? Stuff one wheel, stuff both wheel? They are doing their own thing. Anyways, as Emerson said above, there is debate. I prefer keeping them separate.
I liked the ride of my gen2 but just wanted to improve towing and weight hauling. So I went with bags. Ditto for the gen3. I don't want to change the ride characteristics, just improve the load hauling. Now, if its lift you're after, bags are not a good way, IMHO to gain that. New coils or spacers are the answer. BTW, there is a different number if you're planning to go with longer than OEM coils, such as OME (lol, I love how old man emu and original equipment manuf get mixed up! Sometimes I think we throw it out there just for fun).
If I pull the trigger on the number I posted above, I'll follow up when I put them in. It may happen sooner rather than later. Ahem...
