Like others mentioned I bench built my HP30 with 4.88's, ARB, Moog upper bushings, and Spicer ball joints. And when I was ready swapped front ends out and transferred over my shafts, hubs, and knuckles. I've got 4" Teraflex springs and have caster set to about 6.5*..... Drives fantastic down the highway and has a pretty much perfect pinion angle.
