Basically what the thread is titled. I have a 1500 which right now has a leveling/coil spacer kit in the front but I've came across some 2500 diesel coil spring which should lift it but I'm not sure if they will work with the leveling kit. I'm looking at just adding the coil springs in front and blocks in back to get a little more lift. And if I do go blocks in the rear Ill get one solid block not stack. Figured I'd mention that before someone jumps on my back lol.

 

2500 springs will give you roughly 2" of lift. but keep in mind the higher you go the more your wheels will be pulled back because of your control arms. they may need to be lengthened. and some other things may need to be extended also, like pitman arm, panhard bar, etc...

oh and how does your leveling kit give you 6" of lift? you already have a lift kit on it. why not go with a body lift?

 

Keep in mind the 2500 diesel springs will probably ride like crap because they are meant to support the 1100 lbs cummins and not a V8... 2500 gas springs would be awesome if you could find some.

 

Yep, changing to diesel springs will give you more lift, but they will ride harsh. That being said, I can't say if they would work in combination with the spacers or not as it depends on the size of the spacers. If you go over 3" of lift you need to change out several more parts like the upper and lower control arms, trac bar drop bracket, and several other parts that I can't remember. It's been a while since I've messed around with it, so I can't remember what all you need to replace. So if you ran those coils with a 1" spacer you'd probably be fine. If you ran them with a 3" spacer, you need to put a lot more than just the coils and spacers on there.
