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 world of XJ long arm kits, answering your burning 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 much longer ones. This simple yet profound change drastically alters the suspension's geometry. Instead of short arms that create significant axle wrap and binding during articulation, long arms maintain a more consistent axle position throughout the suspension's travel. This leads to smoother, more controlled articulation, allowing for greater wheel travel and improved stability on uneven terrain.
What are the Benefits of a Long Arm Kit for my XJ?
The advantages of installing a long arm kit on your XJ are substantial:
-
Improved Articulation: This is the primary benefit. Long arms allow the axle to move more freely, significantly increasing the suspension's ability to flex over obstacles. This translates to better traction and less wheel lift.
-
Increased Ground Clearance: By repositioning the axle and offering increased suspension travel, long arm kits provide greater ground clearance, allowing you to tackle more challenging obstacles.
-
Reduced Axle Wrap: Axle wrap, where the axle twists under load, is a common problem with short arm suspensions. Long arms drastically reduce this effect, resulting in improved traction and handling.
-
Enhanced Stability: Improved articulation and reduced axle wrap contribute to better stability, both on and off-road. This makes for a more confident and comfortable driving experience.
-
Increased Wheel Travel: The lengthened arms allow for a greater range of suspension travel, which ultimately increases the vehicle’s off-road capability.
What are the Different Types of Long Arm Kits?
Several types of long arm kits cater to various needs and budgets. These can vary in materials used (steel vs. aluminum), adjustable features, and overall complexity:
- Budget-Friendly Kits: These kits offer a good balance between performance and price but may compromise on some features, such as adjustability.
- High-Performance Kits: These kits typically utilize higher-quality components and offer more adjustability and strength, enhancing durability and performance. Expect to pay a premium for these options.
- DIY Kits: Some companies offer kits designed for those comfortable with fabrication and installation. These often provide more customization but require mechanical skills and specialized tools.
How Much Does a Long Arm Kit Cost?
The price of a long arm kit for your XJ can vary wildly, depending on the brand, quality of components, and features included. Expect to spend anywhere from a few hundred dollars for a basic kit to several thousand dollars for a high-performance, fully adjustable system. Remember to factor in the cost of installation if you're not performing the work yourself.
What is the Best Long Arm Kit for my XJ?
There's no single "best" kit; the optimal choice depends on your budget, driving style, and desired level of performance. Researching different brands and reading reviews from other XJ owners is crucial to making an informed decision. Consider factors like build quality, adjustability, and customer support when making your selection.
How Difficult is it to Install a Long Arm Kit?
Installing a long arm kit is a significant undertaking, requiring mechanical skills, specialized tools, and potentially specialized knowledge of suspension geometry. Many consider it a challenging project best suited for experienced mechanics. If you're not comfortable with this type of work, professional installation is strongly recommended.
What Other Modifications Might I Need?
Installing a long arm kit often necessitates other modifications to optimize performance and safety. These can include:
- Longer Brake Lines: Extended brake lines are typically required to accommodate the increased suspension travel.
- Steering Modifications: Longer steering components may be necessary to avoid binding or interference with the suspension.
- Driveshaft Modifications: Depending on the lift height and amount of axle articulation, driveshaft modifications might be needed to prevent binding or vibrations.
This comprehensive guide should help you understand the intricacies of Jeep Cherokee XJ long arm kits. Remember to always prioritize safety and thorough research before undertaking any modification to your vehicle.
