You can also check out the Kelderman air ride system with full 4 link. Several people who tow/haul heavy have installed this and found that it gave what they wanted.
Having said that a true 4 link can really help but can also be a real PIA if not built or adjusted properly. If not properly adjusted they can be miserable to drive. 4 lonks can bind easily. Adjusted properly traction can be awesome Or lost.
There are some things to consider, will it be a triangulated or parallel system? Will you run a panhard bar or Watts link? Desired ride height? Single or dual coil over? Progressive coils? Air suspension? Anti-dive? Anti-squat? Roll center? Instant center? Pinion angel? Heims, bushings or mix? Poly or solid bushing?
How much weight will you haul/tow? Driving style will have a huge influence on the adjustments and design.
I don't think you will be able to buy a complete turn-key system that requires no adjustment or setup. Just not the nature of a 4 link. If it doesn't weld in I wouldn't run it. If it can't be adjusted it will always be a comprimise. You may well need to ajust for empty vs loaded conditions.
I have no idea what your abilties are but there are many things to consider if you fab your own. Some use DOM I prefer 4130 seamless tube. I avoid Heims and like a mix of poly/rubber/solid bushings. I use adjustable ends on at least the upper bars. Prefer Watts link over panhard bar. I GTAW everything unless it is it just a bracket I might GMAW. Never SMAW.
Try some of the off road forums. Those guys have done amazing things.
