The Jeep Cherokee XJ, a beloved classic, is renowned for its off-road capabilities. However, to truly conquer challenging terrains, many enthusiasts opt for a long arm suspension kit. This upgrade significantly improves articulation, handling, and overall performance, transforming your XJ into a capable trail warrior. This guide delves into the world of Jeep XJ long arm kits, exploring their benefits, considerations, and installation aspects.
What is a Jeep XJ Long Arm Kit?
A long arm suspension kit replaces the factory short control arms with significantly longer ones. These longer arms extend from the axle to the frame, providing increased suspension travel and improved articulation. Unlike short arms which are more prone to binding and limiting suspension movement, long arms allow the axle to move more freely, preventing suspension binding even on uneven terrain. This translates to smoother rides and dramatically improved off-road capability.
Benefits of Installing a Long Arm Kit on Your Jeep XJ
The advantages of installing a long arm kit on your Jeep XJ are numerous:
- Increased Suspension Travel: This is the primary benefit. Longer arms allow for a much greater range of suspension movement, resulting in better articulation over obstacles.
- Improved Articulation: This means your wheels can maintain contact with the ground even when one side is significantly higher or lower than the other. This is crucial for traversing rough terrain.
- Enhanced Handling: While primarily designed for off-road use, a well-installed long arm kit can also improve on-road handling by reducing body roll and providing a more stable platform.
- Increased Ground Clearance: Although not always a direct result, the increased suspension travel often leads to greater ground clearance.
- Reduced Axle Wrap: Long arms help minimize axle wrap, a common issue in high-torque situations where the axle twists under power, reducing traction.
What are the Different Types of Jeep XJ Long Arm Kits?
Several types of long arm kits cater to various needs and budgets:
- Basic Kits: These kits provide the essential long arms, brackets, and hardware for the upgrade. They often require additional components, such as shocks and bushings, to complete the installation.
- Complete Kits: These include everything needed for installation, including shocks, bushings, and other necessary parts. This is often the preferred option for ease of installation.
- Adjustable Kits: These kits offer adjustable control arm lengths, allowing for fine-tuning of the suspension geometry and caster angle to optimize handling and performance. This provides greater customization.
What is the Cost of a Jeep XJ Long Arm Kit?
The cost of a Jeep XJ long arm kit varies considerably depending on the brand, features, and components included. Expect to invest anywhere from a few hundred dollars for a basic kit to several thousand for a high-end, fully adjustable kit. It's essential to research and compare different brands and kits before making a purchase.
How Difficult is it to Install a Jeep XJ Long Arm Kit?
Installing a Jeep XJ long arm kit is a challenging project that requires mechanical aptitude, patience, and the right tools. It's generally considered an intermediate to advanced mechanical task. Many enthusiasts tackle the installation themselves, while others opt for professional installation. Proper alignment is crucial after installation, requiring specialized equipment.
How Much Does it Cost to Install a Jeep XJ Long Arm Kit?
The cost of professional installation can range significantly depending on the location and the shop's labor rates. Expect to pay a substantial amount for professional installation, possibly exceeding the cost of the kit itself.
What are the Common Problems with Jeep XJ Long Arm Kits?
Potential issues include:
- Improper Installation: Incorrect installation can lead to poor handling, premature wear, and even damage to components.
- Component Failure: Like any automotive part, components in the kit can fail over time, requiring replacement.
- Alignment Issues: Incorrect alignment after installation can significantly impact handling and tire wear.
Conclusion
A Jeep XJ long arm kit represents a significant upgrade for serious off-roaders, offering substantial improvements in articulation, suspension travel, and overall performance. However, careful planning, research, and potentially professional installation are crucial for a successful outcome. Remember to weigh the benefits against the cost and complexity before undertaking this modification.
