The Jeep Cherokee XJ, a beloved classic, offers incredible off-road potential. However, to truly unleash its capabilities, many enthusiasts opt for a long arm suspension kit. This upgrade significantly improves articulation, ground clearance, and overall off-road performance. This guide will delve into the intricacies of Jeep XJ long arm kits, addressing common questions and providing valuable insights for those considering this modification.
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 dramatically alters the suspension geometry. Instead of the short arms' limited articulation, long arms allow for much greater axle movement, leading to superior wheel travel and improved traction on uneven terrain. This increased travel minimizes axle wrap and maximizes tire contact with the ground, resulting in a smoother, more controlled ride, especially over obstacles.
Why Choose a Long Arm Kit for Your XJ?
The benefits of a long arm kit extend beyond just increased ground clearance. Here's a breakdown of the key advantages:
- Improved Articulation: Long arms significantly improve the axle's ability to articulate, allowing for better wheel travel and traction over rough terrain. This means fewer instances of getting high-centered.
- Increased Ground Clearance: A long arm lift inherently provides more ground clearance, allowing you to tackle more challenging obstacles without scraping your undercarriage.
- Reduced Axle Wrap: The longer control arms help minimize axle wrap, a phenomenon where the axle twists under stress, reducing traction and potentially damaging components.
- Enhanced Stability: The improved geometry and increased stability translate to a more controlled ride, both on and off-road.
- Better Handling: While primarily focused on off-road performance, long arm kits can also subtly improve on-road handling, although this is less pronounced than the off-road benefits.
What are the Different Types of Long Arm Kits?
Several types of long arm kits cater to various budgets and needs:
- Basic Long Arm Kits: These kits usually offer the essential components – the long arms themselves, brackets, and necessary hardware. They typically require more fabrication and custom work.
- Complete Long Arm Kits: These are all-inclusive, providing everything needed for installation, including shocks, brackets, and hardware. This simplifies the process and reduces the need for additional parts sourcing.
- Budget-Friendly Kits: These kits may use less expensive materials or offer fewer features but provide a more affordable entry point into the world of long arm suspensions.
- High-Performance Kits: These kits employ higher-quality materials and offer superior performance and durability, often including features like adjustable links for fine-tuning the suspension.
How Much Does a Long Arm Kit Cost?
The price of a long arm kit varies greatly depending on the brand, features, and components included. Expect to pay anywhere from a few hundred dollars for a basic kit requiring extensive fabrication to several thousand dollars for a complete, high-performance system. Factor in additional costs for installation, if not performing the work yourself.
What are the Disadvantages of a Long Arm Kit?
While offering significant advantages, long arm kits also have drawbacks:
- Cost: As mentioned, they can be expensive, especially high-performance kits.
- Installation Complexity: Installing a long arm kit can be complex, requiring mechanical skills and potentially specialized tools. Professional installation significantly increases the overall cost.
- Increased Unladen Ride Height: Long arm kits typically raise the vehicle's ride height, which can affect handling and approach angles in some situations.
How Difficult is it to Install a Long Arm Kit?
Installation complexity varies significantly based on the kit's design and the installer's experience. A basic kit might require substantial fabrication and welding, while a complete kit simplifies the process. Even with a complete kit, it's a significant undertaking best suited for experienced mechanics or professional installers.
Do I Need to Replace Other Components with a Long Arm Kit?
Yes, installing a long arm kit often necessitates replacing other components to maximize its benefits. These may include:
- Shocks: Longer travel shocks are essential to accommodate the increased suspension travel.
- Brakes: Depending on lift height, brake lines may need to be extended.
- Steering: Steering components may require adjustment or replacement for proper alignment and geometry.
What are Some Popular Long Arm Kit Brands for XJ Jeeps?
Several reputable brands manufacture long arm kits for XJ Cherokees. Researching each brand's reputation and customer reviews before purchasing is crucial. It's important to note that I cannot provide specific brand recommendations here as this would constitute an endorsement.
This guide provides a foundational understanding of Jeep XJ long arm suspension kits. Always thoroughly research and choose a kit appropriate for your skill level, budget, and off-roading goals. Remember to consult with experienced Jeep enthusiasts and mechanics before undertaking this significant modification.
