The Jeep TJ Wrangler, a beloved off-road icon, has captivated enthusiasts for its rugged capability and customizability. One popular modification to enhance its performance and articulation is installing a long arm suspension kit. This guide delves into the world of Jeep TJ long arm kits, exploring their benefits, considerations, and installation aspects.
What is a Long Arm Suspension Kit?
A long arm suspension kit replaces the factory short control arms with significantly longer ones. These longer arms offer several advantages, primarily by improving suspension geometry and articulation. Instead of the short arms' tendency to bind and restrict wheel travel, long arms allow for greater suspension droop and flex, resulting in smoother rides over rough terrain and improved stability at high speeds.
Why Choose a Long Arm Kit for Your Jeep TJ?
Choosing a long arm kit for your Jeep TJ offers several compelling benefits:
- Improved Articulation: The most significant advantage. Long arms allow for greater wheel travel, enabling the tires to maintain contact with the ground even on uneven surfaces. This leads to improved traction and climbing capabilities.
- Reduced Axle Wrap: Axle wrap, a common issue in high-torque situations, is significantly lessened with long arms. The longer arms provide better leverage against the twisting forces on the axle, preserving traction.
- Enhanced Stability: The improved suspension geometry enhances stability at high speeds, both on and off-road. The controlled suspension movement reduces body roll and improves handling.
- Increased Ground Clearance: Long arm kits typically provide additional ground clearance, allowing you to tackle more challenging obstacles.
What are the Different Types of Long Arm Kits?
Several types of long arm kits cater to different needs and budgets:
- Basic Long Arm Kits: These kits typically offer the core components – longer control arms, brackets, and hardware. They’re a good starting point for those looking for a performance upgrade without breaking the bank.
- Full Long Arm Kits: These comprehensive kits include all necessary components, often including upgraded shocks, links, and potentially even a new steering system. They represent a significant investment but offer a complete solution.
- Custom Long Arm Kits: These kits are tailored to specific needs and preferences, offering maximum adjustability and customization. They are often the most expensive option.
What are the Drawbacks of a Long Arm Kit?
While offering significant performance improvements, long arm kits also come with some drawbacks:
- Cost: Long arm kits are a substantial investment, significantly more expensive than short arm lifts.
- Complexity: Installation is more complex than a short arm lift, often requiring specialized tools and expertise.
- Increased Ride Height: Increased ride height can affect the vehicle's center of gravity and potentially handling on paved roads.
How Much Does a Jeep TJ Long Arm Kit Cost?
The price of a Jeep TJ long arm kit varies considerably depending on the brand, components included, and level of customization. Expect to pay anywhere from several hundred dollars for a basic kit to several thousand for a high-end, custom-designed system.
How Difficult is it to Install a Long Arm Kit?
Installing a long arm kit is a complex undertaking, best suited for those with mechanical experience and the right tools. It often requires extensive disassembly of the suspension, careful measurements, and precise alignment. Many enthusiasts choose to have professional installers handle the installation.
Do I Need to Adjust the Steering After Installing a Long Arm Kit?
Yes, proper steering adjustment is crucial after installing a long arm kit. The change in suspension geometry may necessitate adjustments to the steering linkage to ensure proper alignment and prevent binding. This often requires specialized tools and knowledge.
What are the Best Jeep TJ Long Arm Kits?
Choosing the "best" long arm kit depends largely on individual needs, budget, and driving style. Research different brands and read reviews to find a kit that best suits your specific requirements.
Conclusion
A long arm suspension kit significantly upgrades the off-road performance of a Jeep TJ Wrangler. While it requires a substantial investment and installation expertise, the improved articulation, stability, and ground clearance make it a worthwhile upgrade for serious off-road enthusiasts. Thorough research and careful planning are essential before embarking on this modification. Remember to consult with experienced Jeep mechanics for advice tailored to your specific needs and vehicle.
