Jeremy, I made some calls on your behalf, you can thank me later.
Called Ground Force and chatted with them about buying the front coils only from the 9984 kit. They will sell them for $186, p/n 11935. Call (724) 430-2068, ask for Daric. I told him I already bought some used BT rear coils and didn't want to spend $800 on the GF kit since I only needed front coils.

Then, Stylintrucks has the rear coils only for $137. That would pretty much cover it. My Belltech kit came with 4 coils and 4 bump stops, so you really don't need anything else. I assume you won't need front bump stops for the 4wd since GF doesn't include any bump stops. I would just cut down the factory rear bump stops if needed, the ones that came with my kit look like shorter versions of the stock ones. Rent you a spring compressor for the front and $60 for an alignment and you're dropped for about $400.
