    Ready for Rock Crawling. Hit the trails with confidence with the Currie RockJock 44 Front Crate Axle with Detroit Locker. This full axle swap kit is designed to provide superior strength and durability fit for heavy off-road use.

    Legendary Currie Quality. The RockJock 44 is designed and built to be far superior to the stock Dana 44 axles. The kit features heavily reinforced center section, thicker tube walls, and outstandingly strong Chromoly Axles.

    Professional Installation Recommended. The RockJock 44  is designed as a complete axle-swap kit and requires mechanical expertise. A computer re-tune is required after installation to adjust for the new gearing.

    2-Year Limited Warranty. The Currie RockJock 44 Front Crate Axle with Detroit Locker is warranted to be free of defects in materials and workmanship. Any alteration or improper use voids the warranty. Other exclusions will apply.

    Application. The  Currie RockJock 44 Front Crate Axle with Detroit Locker and 4.88 gear ratio is designed to fit 2007-2018 Jeep Wrangler JK models.

    Application Note. Recommended for optimization of 4 inch lifted vehicles is to set pinion angle to 5 degrees to reduce driveshaft angle. Additionally, 5 degrees of caster for improved steering. Due to limitations of the stock brakes, bearings, and wheel u-joints, maximum tire size is 37 inches.

    Please Note. Currie's RockJock Crate Axles are built to order for our customers and because of this, there can be a 3 to 4 week lead time on orders once your information is received.
