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.
