Rod Hall once told us: "it takes two Hummers to go wheeling. If you get one stuck, only another Hummer is going to get you out again." Zach Harmon will tell you that Chevy Crew Cab 4x4 dualies on 38s should also adhere to Rod's rule. You see, Zach's '87 K30 is just about the biggest truck you're likely to find out in the mud and sand of Southern California.
Based on the heaviest pickup GM ever built, Zach's 454, TH400, NP205, Dana 60 front, Dana 70 rear package reads like a drivetrain wish list. To fit the 38s Zach lifted the truck with an 8-inch suspension lift and had the front fenders cut and recontoured to fit the tires. Zach is tough on his truck, and he can't afford a lot of downtime because he's a busy man. You see, Zach is Metallica's (yes, that Metallica) guitar technician and doesn't get a lot of time to go wheeling--as you can imagine, Zach's day job can be rather demanding. When you work with a rock band for a living you have to do some pretty extreme stuff to have fun. So when he does hit the trails he doesn't hold anything back--he goes where he wants to and plays as hard as he can. Slowly but surely this truck is evolving into a rig that can handle everything Zach can dish out. Now all he needs is a friend with a dualie on 40s!
