The Currie Currectlync® Steering System is a heavy-duty upgrade for Jeep TJ, LJ, XJ, MJ, and ZJ models, designed to enhance steering stability, durability, and performance. This system replaces the stock tie rod and drag link with forged alloy components that are significantly stronger and more robust than the factory parts. According to the manufacturer, the Currectlync system is rated at 200% stronger than the stock components, with no changes to steering geometry that can lead to issues like bump steer. This article provides an in-depth overview of the installation process, key features, and important considerations based on the available documentation and user reports.
Key Features of the Currie Currectlync Steering System
The Currie Currectlync system is engineered to provide enhanced strength and reliability for off-road use. The system includes the following core components:
1 ¼” Diameter Forged Alloy Drag Link: This drag link is significantly thicker than the stock version, offering greater resistance to bending and deformation under stress. The forged construction ensures durability in rough terrain conditions.
1 ¼” Solid Alloy Steel Tie Rod: Unlike the stock tie rod, which is a thin-walled tube, the Currie tie rod is a solid bar with threaded ends. This design eliminates potential weak points and provides consistent performance over time.
7/8” Thread Tie Rod Ends with Boots: The tie rod ends are designed with larger threads for improved strength and are protected by boots to prevent contamination and wear.
Currie Heavy Duty Steering Stabilizer Bracket: This bracket allows for the attachment of a steering stabilizer, which helps reduce vibrations and improves overall steering control.
The system is a direct replacement for the stock parts, requiring no modifications to the vehicle. This makes the installation process relatively straightforward for experienced users or professional mechanics.
Installation Process
Based on multiple user reports and installation guides, the installation process for the Currie Currectlync system involves several key steps. The following sections outline the process in detail.
Step 1: Removing the Stock Components
Before installing the new Currie parts, the stock drag link and tie rod must be removed. This involves disconnecting the tie rod ends from the steering knuckles and removing the old drag link. A tie rod end puller is typically required to separate the ends from the steering components. Users should ensure that the suspension is in a stable position and that the wheels are turned to a neutral position to facilitate removal.
Step 2: Installing the New Drag Link and Tie Rod
Once the stock components are removed, the new Currie drag link and tie rod can be installed. The drag link is positioned between the steering box and the steering knuckle, while the tie rod connects the two front knuckles. It is important to ensure that the tie rod is threaded correctly and that the rod ends are fully seated before tightening.
Step 3: Torquing and Securing the Components
After the new parts are in place, the castle nuts at the tie rod ends must be torqued to the specified 55 ft. lbs. as per the manufacturer's instructions. Once torqued, cotter pins are inserted into the castle nuts to prevent loosening during use. This step is critical to ensuring that the components remain secure under the stresses of off-road driving.
Step 4: Adjusting Toe-In
Proper toe-in adjustment is essential for maintaining steering stability and tire wear. The Currie system allows for manual adjustment of the tie rod to achieve the desired toe-in. Users should measure the difference in length between the left and right sides of the tie rod and adjust until the difference is approximately 1/8 inch. This step may require multiple iterations to get the alignment just right.
During the adjustment process, users should also check for clearance between the tie rod and surrounding components. The Currie instructions advise ensuring that the passenger side clamp does not interfere with nearby brackets when the suspension is in motion. Some users have reported needing to slightly rotate the tie rod to avoid hardware collisions.
Step 5: Installing the Steering Stabilizer
Once the toe-in is set, the steering stabilizer can be attached to the drag link. The stabilizer is bolted to the bracket and loosely attached to the drag link before final positioning. The stabilizer should be adjusted so that approximately 1/4 inch of the shaft is exposed when the steering wheel is turned fully to the right. This ensures that the stabilizer functions correctly during extreme steering angles.
Step 6: Final Checks and Adjustments
After all components are installed and adjusted, a final inspection is recommended. Users should check that all bolts are properly tightened, that there is no interference between moving parts, and that the steering feels smooth and responsive. A test drive is also advised to ensure that the system functions as intended and that there are no unusual noises or vibrations.
Additional Considerations
Lift Requirements
The Currie Currectlync system is designed for vehicles with up to a 4-inch lift. However, it can also be used on vehicles with less lift, provided that a minimum of a 2-inch bump stop is installed. For vehicles without any lift, some users have found that the tie rod ends may need to be trimmed to achieve proper adjustment. This is an important consideration for users planning to install the system on a stock-height vehicle.
Grease Fitting Solutions
One common issue reported by users is the potential for clearance problems with the standard grease fittings on the tie rod ends. To address this, some users have opted to install a flush-style grease fitting from McMaster-Car. This fitting protrudes only about 1/8 inch and allows for easier access to the rod ends during maintenance. Users can remove the flush plug, temporarily screw in a standard grease fitting, and perform the lubrication task. This solution has been effective for avoiding interference with surrounding components.
User Experience and Performance
Several users have reported positive experiences with the Currie Currectlync system after installation. The system is praised for its robust construction and the noticeable improvement in steering stability. One user noted that the Currie drag link and tie rod were significantly beefier than the factory parts, with the tie rod measuring 1.25 inches in diameter compared to the stock 0.875 inches. The solid rod design is expected to provide long-term reliability and resistance to bending.
Users also appreciate the straightforward installation process, particularly for those with prior mechanical experience. The system requires minimal modifications and can be installed in a single day with the help of a partner. The use of a tie rod end puller and an alignment tool were cited as helpful tools during the process.
Conclusion
The Currie Currectlync® Steering System offers a reliable and durable upgrade for Jeep TJ, LJ, XJ, MJ, and ZJ models. With its 1 ¼-inch forged alloy drag link and solid steel tie rod, the system provides enhanced strength and steering stability compared to the factory components. The installation process is relatively straightforward, with detailed instructions available to guide users through each step. Proper toe-in adjustment and steering stabilizer installation are critical to achieving optimal performance. Additionally, users should consider lift requirements and potential clearance issues with grease fittings to ensure a smooth installation.
For off-road enthusiasts and Jeep owners looking to improve the durability and performance of their steering system, the Currie Currectlync system is a highly recommended upgrade.
