Look closely at the photo. Do you know what axle it is? The spool permanently "locks" the 5.87s gears in the Dana 70. "Unfortunately," Kim says, "the inner axles are 30-spline, so I manage to snap one every couple of years." And because of the weak 30-spline inners, he's going to machine some new 35-spline axleshafts from chrome moly. Suspension mods include a total lift of 14 inches from 7 inches of National Springs, a 4-inch spring-over, and 3 inches from a self-fabricated body lift.
