    All In One. The Jeep Wrangler has always been known to be able to go just about anywhere and do just about anything. However, if you’re looking to crawl over some of the steepest inclines and the largest boulders, then some significant modifications are in order. A good place to start would be completely replacing the rear axle with the Currie RockJock 60 Rear Crate Axle with Eaton Locker - 4.56 Ratio. 

    Great Crate.  The crate axle is comes with beefed up components including 4340 chromoly axles, a strengthened 60 rear axle, AR400 rear skid plate and a new 4.56 ratio, all of which make it twice as strong as the factory rear axle. The crate axles also incorporates a high-pinion radius bottom center and a larger diameter out pinion to make it better suited for the off-road while allowing for up to a 4-inch lift and 37-inch tires.  

    Hard Installation. The rear crate axle can be installed by a professional mechanic in about 6 hours. 

    Warranty Information.  The rear crate axle is backed by a 2-year warranty. Please check the manufacturer’s site for more details.  

    Application. The Currie RockJock 60 Rear Crate Axle with Eaton Locker - 4.56 Ratio fits all 2007-2018 Jeep Wrangler JK models.
