    Rock The Crate. Modifying your Jeep Wrangle for the great off-road is just as about fun as actually driving it on rocky terrain. However, if you’re looking to get up and over much more than just dirt trails, your Jeep is going to need a good amount of work. Enter the Currie RockJock 44 Front Crate Axle with Zip Locker - 4.56 Ratio. It is a direct bolt-in replacement to the factory axle with some serious hardware for the serious trails. 

    Zip Locker. The crate axle includes a zip locker, a new 4.56 ratio, and 4340 chromoly axles. This unit is twice as strong as the factory front end as it has a strengthened front housing and differential and utilizes a low-pinion, nodular iron-center section with thicker walls. If you’re worried about keeping your lift height intact, this crate axle has you covered as it can accommodate up to a 4-inch lift and 37-inch tires. 

    Hard Installation. A professional mechanic should be able to install the crate axle in about 6 hours. 

    Warranty Information. The front crate axles comes with a 2-year warranty. Please check the manufacturer’s site for more details.  

    Application. The Currie RockJock 44 Front Crate Axle with Zip Locker - 4.56 Ratio fits all 2007-2018 Jeep Wrangler JK models.
