Magnum Force Has better design and strength. After 4 years of checking around and comparing suspension of 5 choices, I went with the Transformer. Easy to assemble, improved geometry, track proven, k-member strength is like 5 times stronger than stock (and most others out there). Suspension parts are not the 'mustang II' style most shops use. I have two builds going on right now and using their parts on both of them. I even plan on using their lower control arms on a future off-road project in the future.
Better and stronger...by comparing all the manufacturers propaganda or as verified by a third party? Anyone can say anything and assign numbers to it from their solidworks program and then sell it so I'm always leery of big claims like 5 times stronger than stock.
The Transformer set up looks massive, yet they are also claiming lighter weight than stock. Looking at the shear size of those parts and combined with their lightweight claim, they must be constructed of some thin wall material. That would give me some pause for a street vehicle. Maybe they are great, maybe not. I really don't know since I've not used any of their stuff. One thing I do like about the XV set ups is they are using OEM proven components from C4 Vettes. GM put more R&D and testing into those than all the mopar aftermarket manufacturers combined. I'd tend to say they are pretty sound.
