Big guy-first off, a hearty welcome to The 'Bolt...

That said, The biggest recommendation I would make is
stick with products from the same manufacturer. Sounds obvious, but you'll be sure to have a pile of stuff that will all work together if you buy all from the same place. Next thing to do is come up with a game plan for your project
and stick with it! Do you "just" want a basic MII I.F.S.? Do you want a full-blown adjustable airbag suspension setup? Again, compatibility is the big issue here-in most cases, if you buy an airbag setup, then decide you just want coils or coilovers, you'll be SOL-the stuff won't be compatible, as the airbag crossmember was engineered for use with airbags.
As for different manufacturers, as you say lots out there. We used to have a pro rod builder here who
hated Fatman Fabrications and swore by Heidt's Hot Rod Shop stuff. I'm sure you'll get many posts from different folks here who've done this conversion and their thoughts on the different kits available.
By the way,
what kind of truck do you have?! :confused: That tidbit will be helpful for future postings.

Best of luck with your project.
Regards,
Wannabe
