No stranger to leading the market in innovation and design, Currie Enterprises is at it again. Its latest industry-first is the Rock Jock 60, an aluminum high-pinion Dana 60 axlehousing. Barely tipping the scales at 25 pounds, the Rock Jock 60 is ideal for competition rockcrawling vehicles, but it's also a great upgrade for weight-conscious trail rigs. However, the Rock Jock 60 is more than just a lightweight axlehousing. With its 60-degree cover angle to maximize ground clearance and unique flow-through oiling system, the Rock Jock 60 offers strength, function, and reliable performance all in one package.
The Rock Jock 60 high-pinion differential housing is constructed from 206T6 aluminum, which is commonly used in aircraft applications. This superior-grade aluminum offers less porosity, allowing for fewer air bubbles throughout the casting and for the surface to maintain its polish for a longer period of time. The Rock Jock also uses an oversized pinion bearing and billet aluminum bearing caps. The high-pinion design accepts all reverse-rotation Dana 60 gearsets and stock and aftermarket differential covers.
Currie offers the Rock Jock to fit many applications and can outfit the new differential with the proper suspension brackets for a bolt-in installation. The Rock Jock also features threaded mounting holes to accommodate top-mounted controls arms and triangulated suspension configurations. To protect the underside of the new lightweight housing, Currie includes its Jock Strap skidplate, constructed from AR400 heat-treated carbon steel. The Jock Strap is bolted to the housing via threaded holes in the casting.
As with all of its custom differentials, Currie offers the Rock Jock 60 fully assembled or in parts. Assembled units accept 3x0.3125-inch or 3x0.375-inch wall axle tubes and include the Jock Strap skidplate and a heavy-duty steel differential cover.
