Want to talk flotation tires? Zach runs four 38x12.5-16.5 Swamper TSLs to make sure he can pull his desert toys over any terrain in Southern California without sinking or getting stuck. The factory Dana 70 rear axle has been fortified with 4.88 gears, a Detroit Locker, and a Go Rhino axle truss, so the weak link in the rearend is now actually the U-bolts! How do we know? Zach's got home video that shows him turning all four of them into pretzels as the rear driveshaft went into orbit when he combined a little too much throttle with all that tire on a tough hillclimb.
