they run the same frame. they don't have a 'suspension lift'. and they don't have a front 'axle'. they're IFS with Fox 2.0 Coilovers, and huge lower a-arms. the a arms, and rear diff widen the truck, and with the extra length you get way more travel. the truck, due to its design, sits ~3" higher than a comparable f series.
the rear is running remote reservoir foxs again, and have progressive bump stops. Looking at the truck in 'after' pics, she's still sitting at ride height all around...
these trucks are capable of a lot. i've gotten a few feet of air and it doesn't feel like it....but to attempt to blast over this hill at the speed he did....well....he should just give me his truck for parts.
