Dynatrac ProRock 44 Package - Assembled - JL Rubicon Width

The Dynatrac ProRock 44™ for the 2018 and newer Jeep Wrangler JL and the 2019 and newer Jeep Gladiator JT has significantly stronger axle tubes and end forgings. This serious upgrade in strength and durability, along with the elimination of the Front-Axle Disconnect (FAD), provides JL and JT owners with the Confidence to Explore® and the ability to run tires up to 38-inches tall without fear.

The ProRock 44™ is a direct replacement housing for the Jeep JL front axle. It is available in two widths to match the stock axle widths in Sport/Sahara/Overland models, as well as the wider Rubicon model. This axle is significantly stronger than the factory Dana 44, addressing the critical areas that fail when larger tires are installed and the vehicle is used regularly off-road.

ARB Air Locker’s patented design has proven to be an ultra-dependable product, even under the most arduous conditions. It’s strength lies within the simplicity of the design, the minimal the moving parts ensures maximum reliability. All structural components are manufactured from aerospace grades of high alloy steel, and where possible, they have increased the number of differential pinion gears to distribute torque loads evenly. Many recent Air Locker designs also utilize timed gear sets to further improve strength, a design feature that has led to a second US patent on the product.

Dynatrac HD ProSteer Ball Joint Kit Features:

Improved steering and driver control

Completely rebuildable

Heat-treated, precision ground stainless steel ball

High-strength billet bodies with chromoly stems

Snap ring design eliminates potential movement

Designed to meet exact OEM quality standards

Engineered to provide reliable performance

High-Quality Performance Ball Joint Kit Have you noticed your vehicle wandering on the road, a decreased steering feel, extra wobble, or tire-tread cupping and feathering? If so, it's time to upgrade to the Dynatrac HD ProSteer Ball Joint Kit as it features 4 balljoints, 4 nuts, 4 cotter pins, and 2 safety snap rings. With larger tires, factory balljoints can develop excessive play and movement in as little as 20,00 miles. In order to prevent this from happening, Dynatrac's ProSteer Ball Joint Kit will provide improved steering, strength, and control to your vehicle thanks to the hardcore construction of these ball joints. While the factory balljoints use a nylon insert to house the ball socket in the opening, Dynatrac's HD balljoints use a heat-treated, precision-ground stainless steel ball in a heat-treated, high-strength billet body. This reduces wear to the unit over time to provide impressive durability even during the most extreme applications. Premium Construction & Installation Info Your OEM balljoints often wear quickly with larger off-road tires, so Dynatrac designed their HD Balljoints using high-strength billet bodies and chromoly stems for maximum strength and long-lasting durability. Moreover, these ball joints are completely rebuildable without requiring the balljoint body to be removed from the axle housing. Dynatrac also makes their HD Balljoints with a snap ring to lock the bodies in position as an extra safety provision. Unique seals prevent contamination, and the balljoints have greaseable fittings and Teflon-coated wear points to provide a long, durable life. Installation is made simple an straightforward as these were designed as a direct replacement of your factory components.
