The Jeep TJ Wrangler, a beloved icon of off-roading, can be further enhanced with a long arm suspension kit. This upgrade significantly improves articulation, ride quality, and overall off-road performance. But choosing the right kit can be daunting. This comprehensive guide will navigate you through the world of Jeep TJ long arm kits, answering common questions and helping you make an informed decision.
What is a Long Arm Suspension Kit?
A long arm suspension kit replaces the factory short control arms with significantly longer ones. This seemingly simple change drastically alters the suspension geometry. Longer arms allow for greater suspension travel, reducing axle wrap and improving articulation – the ability of the wheels to maintain contact with the ground even on uneven terrain. This results in a smoother, more controlled ride, especially on challenging trails. The increased travel also allows for the use of larger tires without compromising ground clearance or causing suspension bind.
What are the Benefits of a Long Arm Kit for my Jeep TJ?
The advantages of installing a long arm kit on your Jeep TJ are numerous:
- Improved Articulation: The longer control arms allow for significantly more wheel travel, improving articulation and keeping tires on the ground even when severely flexed.
- Reduced Axle Wrap: Axle wrap, where the axle twists under power, is greatly reduced, leading to better traction and control.
- Enhanced Ride Quality: The increased suspension travel absorbs bumps and irregularities more effectively, resulting in a smoother, more comfortable ride, both on and off-road.
- Increased Ground Clearance: A long arm lift typically provides more ground clearance than a short arm lift.
- Better Handling: While not always the primary focus, long arm kits can improve handling on-road, especially when combined with appropriate shock absorbers.
What are the Different Types of Long Arm Kits?
Long arm kits vary in design, materials, and features. Some key distinctions include:
- Material: Kits are typically made of steel or aluminum. Steel is stronger and more durable, while aluminum is lighter.
- Adjustability: Some kits offer adjustable control arms, allowing for fine-tuning of suspension geometry.
- Components: Kits may include various components such as shocks, brackets, and hardware. Consider whether you need a complete kit or just the arms themselves.
- Lift Height: Kits are available for various lift heights, ranging from mild to extreme. Choose a lift height that suits your needs and driving style.
How Much Does a Long Arm Kit Cost?
The cost of a Jeep TJ long arm kit varies significantly depending on the brand, materials, features, and complexity. Expect to pay anywhere from a few thousand dollars to well over $5,000 for high-end kits. Remember to factor in the cost of installation, which can be substantial, requiring specialized knowledge and tools.
What is the Best Long Arm Kit for a Jeep TJ?
There isn't a single "best" long arm kit, as the ideal choice depends on your specific needs, budget, and driving style. Research different brands and read reviews to find a kit that meets your requirements. Consider factors like the quality of the components, adjustability, and warranty offered.
How Difficult is it to Install a Long Arm Kit on a Jeep TJ?
Installing a long arm kit is a challenging project, requiring significant mechanical skills and expertise. It's generally recommended to have the installation performed by a qualified professional unless you have extensive experience with Jeep suspension modifications. Improper installation can lead to safety hazards and performance issues.
Do I need a Long Arm Kit for 35-inch Tires?
While not strictly required for 35-inch tires, a long arm kit is highly recommended, particularly for serious off-roading. The increased articulation and reduced axle wrap will prevent binding and improve overall performance with larger tires. Short arm lifts struggle with the increased stress of larger tires, making a long-arm setup a worthwhile investment for improved reliability and handling.
What are the Drawbacks of a Long Arm Kit?
While offering significant benefits, long arm kits do have some drawbacks:
- Cost: They are considerably more expensive than short arm kits.
- Complexity: Installation is more complex and often requires professional help.
- Ride Height: Depending on the kit, ride height can be affected.
This comprehensive guide should help you navigate the world of Jeep TJ long arm kits. Remember that thorough research and careful consideration are crucial before making a purchase. Consult with experienced Jeep mechanics and off-road enthusiasts to ensure you select a kit that matches your needs and budget.
