The Jeep TJ Wrangler, a beloved off-road icon, is often modified for enhanced performance. One popular upgrade is a long arm suspension kit. But what exactly is a long arm kit, and why would you choose one for your TJ? This comprehensive guide will delve into the details, answering common questions and helping you decide if a long arm kit is right for your Jeep.
What is a Jeep TJ Long Arm Suspension Kit?
A long arm suspension kit replaces your Jeep TJ's short control arms with significantly longer ones. These longer arms offer several key advantages, primarily improving articulation and reducing suspension bind. Instead of the short arms' limited range of motion, long arms allow for much greater wheel travel, leading to a smoother ride and improved performance over rough terrain. This increased articulation means your tires maintain better contact with the ground, even when one wheel is significantly higher than the other.
What are the benefits of a Jeep TJ long arm kit?
The benefits of a long arm kit extend beyond just increased articulation. Let's explore some key advantages:
- Improved articulation: This is the most significant benefit. Long arms allow for greater wheel travel and maintain better tire contact with the ground, even on uneven terrain. This translates to significantly improved traction and stability.
- Reduced suspension bind: Short arms are prone to binding, restricting wheel travel and reducing efficiency. Long arms minimize this binding, allowing for a smoother, more controlled ride.
- Increased ground clearance: The longer arms contribute to increased ground clearance, making it easier to navigate obstacles and avoid damage to the undercarriage.
- Better handling on and off-road: The improved suspension geometry enhances both on-road handling and off-road performance. This results in a more predictable and controlled driving experience.
- Enhanced stability: Improved articulation and reduced bind lead to enhanced stability, particularly at higher speeds and on challenging terrain.
What are the drawbacks of a Jeep TJ long arm kit?
While long arm kits offer numerous benefits, it's crucial to acknowledge potential drawbacks:
- Increased cost: Long arm kits are significantly more expensive than short arm or other suspension lift kits.
- Increased complexity of installation: The installation process is more complex and often requires professional assistance.
- Potential for increased axle wrap: While long arms generally mitigate axle wrap, it's still a consideration, especially with larger tires and significant torque. This often necessitates additional upgrades like an anti-wrap bar.
- Increased vehicle height: The increased lift height can affect approach and departure angles, potentially requiring further modifications.
What are the different types of Jeep TJ long arm kits?
Several types of long arm kits are available, varying in features, components, and price:
- Basic long arm kits: These kits provide the fundamental long arm components, focusing on articulation improvement.
- Advanced long arm kits: These kits include additional features like adjustable control arms, higher-quality components, and improved geometry for enhanced performance.
- Kits with adjustable track bars: These kits include an adjustable track bar to center the axle and maintain proper alignment after installation. This is essential for maintaining proper handling and preventing premature wear on components.
How much does a Jeep TJ long arm kit cost?
The cost of a Jeep TJ long arm kit can vary significantly based on the brand, components, and features. Expect to pay anywhere from a few hundred dollars for a basic kit to several thousand for a high-end, fully adjustable system.
How difficult is it to install a Jeep TJ long arm kit?
Installing a long arm kit is significantly more complex than installing a short arm kit or a simple lift. It often requires specialized tools, mechanical skills, and a solid understanding of suspension geometry. Professional installation is highly recommended.
Do I need other upgrades with a long arm kit?
While a long arm kit significantly improves your Jeep's capabilities, complementary upgrades are often recommended for optimal performance and longevity. These might include:
- Larger tires: To take full advantage of the increased articulation.
- Stronger axles: To handle the increased stress from the enhanced wheel travel.
- High-clearance fenders: To prevent tire rubbing.
- Steering stabilizer: To improve steering response and stability.
Conclusion
A long arm suspension kit can transform your Jeep TJ's off-road capabilities, providing a smoother, more controlled, and more capable ride. However, it's a significant investment that requires careful consideration of the costs, installation complexities, and potential need for additional upgrades. Weighing the benefits against the drawbacks, and understanding your own off-roading needs, will help you determine if a long arm kit is the right choice for your Jeep TJ.
