Dynatrac ProRock 44 Unlimited Package - Assembled

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.

The ARB air locker differential is made from aerospace-grade high alloy steel for the ultimate in strength and durability. It is designed with simplicity in mind and features few moving parts for added reliability. This air locker differential provides excellent traction control both on the street and on the trail, so your Jeep can power through harsh road or weather conditions.

Please Note: This is not a direct fit to any OE applications.

The Eaton Elocker has been designed to handle a variety of assignments. Anything from towing, rock climbing, and everything in between. This has been a popular component among the 4x4 community for its smooth operation and reliable strength. These are available for both front and rear axles, and you will notice improvements in both traction, and maneuverability. 

These are controlled though a flip of a switch. When in the “off” position, the differential will be fully-open. When activated into the “on” position, the electronic mechanism will lock the internal differential gear case providing 100% axle lock.

Other features include:
•    Push-button operation.
•    Designed with four (4) alloy pinion gears to withstand high levels of torque.
•    Net forged gears provide greater strength over competitors machine-finished gears. 
•    Locking collar is timed for smooth, consistent engagement.

Please note that  the 2007+ JK uses the 3.73 & down carrier because of thick gears.

Part numbers:
•    3.73 and down gear ratio – 19977-010
•    3.92 and up gear ratio – 19969-010

NOT FOR RUBICON HOUSINGS

The Rancho® High-Steer Knuckles maintain steering geometry and add strength to the most vulnerable points within the steering envelope when off-road driving. The knuckles add an additional 1.5-inches of clearance within the tight space, helping to protect critical steering components, and their design also helps lift the steering linkage out of range from direct impact from off-road obstacles or impediments. The High-Steer Knuckles are precisely engineered and heavy-duty for Left Hand and Right Hand Drive, 3-inch and higher lifted Jeep Wrangler JK’s. The kit includes: a front left High-Steer Knuckle, a front right High-Steer Knuckle and 3-inch bump stops. This product offers a Limited Lifetime Warranty. A 3-inch Track Bar Relocation Bracket is required and is sold separately if your lift does not have one (RS62101). A flipped drag link is also required and is sold separately.

Fits JK Dana 30, JK Rubicon Dana 44

Adds critical strength and height to off-road JK’s

Aligns the geometry of the track bar and drag link to reduce bump steer

Constructed from high-strength steel

Compatible for left- and right-hand drive models

Limited Lifetime Warranty

Requires use of 3-in. track bar mount – (sold separately)

Requires use of a flip drag link – (sold separately)

The Reid 30/44 Left Side Steering Knuckle is designed for Dana 30/44 axles and are heavy duty stock replacement knuckles. Raised steering linkage, dual steering stops, and increased strength are a few of the key improvements made to these Jeep JK steering knuckles. The design allows for the OEM outers to be reused, which simplifies installation. The assembly uses stock brake rotors, calipers, stub shafts and U-joints and fits Mopar and aftermarket axles, as well. No machining is required for installation, allowing for the easy, bolt on install that off roaders have come to expect from Reid products. Aftermarket high strength axle shafts, U-joints/CV joints, and stub shafts can be used and the steering knuckle renders antilock brakes, traction control, and electronic stability control systems fully operational. The 30/44 steering knuckle allows the steering linkage to be raised significantly while retaining clearance for OEM Jeep and most aftermarket wheels. With installation of the steering knuckles, the tie rod gains 1.5 inches of clearance to minimize vulnerability to trail damage. When the drag link is flipped, the rig gains 3 inches of height to perfectly correct the steering geometry necessary to accommodate the typical 3-4 inch suspension lift. Requires an aftermarket drag link, and we recommend a track bar bracket to eliminate bump steer. The Reid steering knuckle is cast from high strength ductile iron and is beefed up with extra material and ribbing. Cast-in dual steering prevents bent stop bolts that can result in u-joint and axle failures. Tapered tie rod holes accept heavy duty one ton tie rod ends that are commonly used in most aftermarket steering linkage. Factory tie rod ends may require slight modification. The knuckle is powder coated bright orange for long lasting looks.

The Reid Dana 30 and Dana 44 Steering Knuckles are super heavy duty knuckles designed to replace your factory knuckles. The Reid knuckles feature raised steering linkage, as well as duel steering stops.  These are a complete bolt-on design to allow your factory antilock brakes, Electronic Stability Control systems, as well as your Traction Control to remain fully operational.

These have also been designed to accept aftermarket high strength axle shafts and U-Joints/CV joints. The steering linkage has been designed to be raised to accommodate aftermarket wheels.  And the clearance for the tie rods gain a 1.5 inch advantage. 

For those of you with a 3-4 inch suspension lifts, you will find that the drag link on Reid Knuckles have been flipped for a gain of 3 inches. This improves the steering geometry which allows minimal steering correction for taller lift kits. Aftermarket drag link is required, and a track bar bracket is recommended to eliminate bump steer. 

These have been crafted out of high strength ductile iron, and the cast-in dual steering stops are designed to prohibit bent stop bolts that can cause u-joint and axle failures. Lastly these have been powder-coated bright orange for years of protection against corrosion.

Equip your vehicle with this heavy-duty front track bar bracket from Synergy Manufacturing. This bracket centers the track bar near the axle centerline and raises the suspension roll center by up to three inches. This helps to reduce body roll, offering a smoother driving experience and better overall handling. The bracket can be trimmed to accommodate track bars up to three inches over stock height. This high-strength steel bracket is designed to be welded on for additional strength and durability.
