    Built for the Trail. The Currie RockJock 44 Front Crate Axle with Grizzly Locker - 4.88 Ratio is an ideal solution for upgrading your JK to tackle the most difficult trails. The reinforced axle assembly is far superior to the factory Dana 44 and comes with the reliable Grizzly locker and a set of 4.88 ratio gears.

    High Quality Construction. Currie made the the RockJock 44 to withstand a beating that the stock Dana 44 can't handle. It features a heavily reinforced center section, larger and stronger tubes, forged inner knuckles, and other features that help it deal with off-road hazards.

    Mechanical Expertise Required. The RockJock 44 is a complete axle-swap kit and requires expertise to install. Furthermore, a computer re-tune is required after installation.

    Two-Year Limited Warranty. The Currie RockJock 44 Front Crate Axle with Grizzly Locker - 4.88 Ratio 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 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, 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.
