    Ideal for Extreme Trails. The Currie RockJock 44 Front Crate Axle with Grizzly Locker - 5.38 Ratio is a great solution for making the JK ready for off-road adventures. Not only can this kit endure conditions that will break the factory Dana 44, it reduces costs by reusing the outer knuckle assemblies. Furthermore, the kit includes the reliable Grizzly locker and a set of 5.38 ratio gears for improved performance.

    Superior Currie Standard. Currie is renowned for its high-quality and the RockJock 44 is a fine example of their expertise. Every component is made with precision from high-grade materials to deliver strength, toughness, and durability fit for heavy off-road usage.

    Mechanical Expertise Required. Swapping out the front axle requires expertise and the services of a professional mechanic are recommended. Additionally, a computer re-tune must be performed for 2012 and newer JKs.

    Two-Year Limited Warranty. The Currie RockJock 44 Front Crate Axle with Grizzly Locker is warrantied 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 Grizzly Locker and 5.38 gear ratio is designed to fit 2007 to 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, set 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.
