When I stole my 1948 Willys pickup from the wife's cousin for a song some months ago, I started planning its buildup using some of the biggest, baddest parts around. But big and bad doesn't need to mean heavy and bulky.
Enter the Currie Enterprises aluminum Rock Jock that's going under the front of this rig. Despite having 1 1/2-inch, 35-spline inner and outer 4340 alloy shafts, a Detroit Locker, 3-inch and 0.375 wall DOM axletubes, our front axle tickles the scales at a mere 344 pounds.
That includes the steering arms, spring pads, 1350 yoke, brakes, and everything else (minus the steering linkage). When you consider how strong the components are, the weight is insane. We visited the company's shop and looked over their shoulder as they assembled the front axle in a few hours.
With a WMS-WMS measurement of 70 inches, the axle looks like it belongs on a full-size more than a Jeep, but I'm building a low and wide wheeling monster, not a show queen. Tune in next issue to see what's going on in the rear.
