Jeep XJ Long Arm Kits: Ultimate Guide

Are you looking to upgrade your Jeep XJ's suspension for improved off-road performance and ride quality? A Jeep XJ long arm kit is often the best solution. In this comprehensive guide, we'll dive deep into everything you need to know about long arm kits for your XJ, covering benefits, considerations, and installation essentials. Our analysis shows a properly installed long arm kit can transform your Jeep’s capabilities.

Why Install a Long Arm Kit on Your Jeep XJ?

A long arm kit replaces your Jeep XJ's factory short control arms with longer arms that offer a variety of performance benefits, making them a popular choice for serious off-road enthusiasts. Let’s explore the key advantages:

Enhanced Articulation

Longer control arms significantly increase wheel travel, allowing your Jeep to navigate challenging terrain with greater ease. This improved articulation keeps your tires in contact with the ground, maximizing traction and control.

Improved Ride Quality

By changing the suspension geometry, long arm kits generally improve ride quality both on and off-road. The longer arms reduce the harshness associated with short arm setups, providing a smoother ride.

Reduced Binding

Longer arms minimize the binding that can occur with short arm suspensions, especially during extreme articulation. This reduces stress on components and enhances the longevity of your suspension system.

Increased Ground Clearance

While not always a primary benefit, many long arm kits also provide a lift, increasing ground clearance and allowing for larger tires.

Superior Stability

The longer arms contribute to a more stable platform, particularly at higher speeds and when traversing uneven surfaces. — NFL Preseason Games Today: Schedule, How To Watch & More

Key Considerations When Choosing a Long Arm Kit for Your Jeep XJ

Selecting the right Jeep XJ long arm kit involves several critical factors to ensure you achieve the desired performance and maintain optimal safety. Consider these aspects:

Lift Height

Long arm kits are designed for specific lift heights. Make sure to choose a kit that matches your desired lift and tire size. Improper matching can lead to alignment issues and reduced performance.

Construction Materials

Look for kits made from high-quality materials like DOM (Drawn Over Mandrel) tubing or forged steel for maximum strength and durability. These materials are built to withstand the stresses of off-road use.

Suspension Geometry

Examine the design of the kit to ensure it corrects the suspension geometry and minimizes issues like caster and pinion angle problems. The best kits provide comprehensive adjustments.

Ease of Installation

Installation complexity varies between kits. Some are bolt-on, while others require welding and fabrication. Evaluate your own skill level and the tools available when making your choice. This is critical for a successful outcome.

Component Quality

Pay attention to the quality of included components, such as control arm bushings, joints, and hardware. High-quality components lead to increased longevity and improved performance.

Comparing Different Long Arm Kit Designs

Different long arm kit designs offer varied approaches to improving the XJ's suspension. Understanding these differences can help you make an informed decision.

Full Long Arm Kits

These kits typically replace all the factory control arms with long arms. They often offer the most comprehensive improvement in articulation and ride quality. However, they may require extensive modifications and installation time.

Mid-Arm Kits

Mid-arm kits use longer control arms but may retain the factory mounting points in the front. This design offers an easier installation compared to full long arm kits while still providing significant improvements.

Radius Arm Kits

Radius arm kits use a single, long arm per side, which connects to a single point on the axle. They are relatively simple to install, but may not offer the same level of articulation as a full long arm kit. These are often seen as an entry-level option.

Installation Process: Step-by-Step Guide

Installing a Jeep XJ long arm kit can be a complex project, especially for full long arm kits. Here’s a general overview of the steps involved: — Who Dakota Cheated On Taylor With? Season 3

Preparation

1. Gather all necessary tools and safety equipment (jack stands, wrenches, impact gun, etc.).
2. Read the kit’s instructions thoroughly. This is crucial for success.
3. Safely lift and secure your Jeep XJ on jack stands.
4. Remove the existing suspension components (control arms, shocks, springs).

Component Installation

1. Install the new long arm brackets onto the frame. This may involve welding, depending on the kit.
2. Attach the long control arms to the frame brackets and axle brackets.
3. Install new springs and shocks.
4. Re-install or replace any necessary components such as brake lines.

Alignment

1. After installation, you’ll need to have the Jeep professionally aligned to ensure proper handling and tire wear. This is essential for safety and performance.

Note: Always consult a professional if you're not confident in your ability to perform these steps. Improper installation can affect the performance and safety of your vehicle. Seeking professional help is always a good idea if you are in doubt. — Erin Moriarty's Transformation: Before & After Rumors

Maintaining Your Jeep XJ Long Arm Kit

Regular maintenance is crucial to ensuring your long arm kit performs optimally and lasts for many years.

Regular Inspections

Inspect all components (control arms, bushings, joints, and hardware) frequently for wear, damage, or looseness. Check the components every few off-road trips or every oil change.

Lubrication

Grease all greaseable components according to the manufacturer’s recommendations. This minimizes friction and helps prevent premature wear.

Hardware Checks

Periodically check all bolts and nuts for tightness, especially after off-road use. Torque them to the manufacturer's specifications.

Bushing Replacement

Bushings will wear out over time. Replace them as needed to maintain ride quality and prevent excessive play.

FAQs About Jeep XJ Long Arm Kits

What is the average cost of a Jeep XJ long arm kit?

The cost can range from $800 to $2500 or more, depending on the brand, features, and level of fabrication required. Some kits offer a better value proposition when considering the price, and the installation required.

Can I install a long arm kit myself?

Yes, but it depends on your skill level and the kit's complexity. Bolt-on kits are easier to install than kits requiring welding. A garage and good set of tools is essential. A great DIY guide is available on the Jeep XJ forums, and these can be invaluable.

Will a long arm kit improve my Jeep’s on-road handling?

Yes, in many cases, long arm kits improve on-road handling by enhancing ride quality and stability. However, the degree of improvement depends on the kit's design and your driving style.

Do I need to re-gear my axles after installing a long arm kit?

Re-gearing may be necessary if you install larger tires. The long arm kit itself doesn't require re-gearing, but larger tires change your gear ratios, so it becomes necessary. Always match your gearing to your tire size for optimal performance.

Where can I find reputable brands for XJ long arm kits?

Popular and reputable brands include Iron Rock Off Road, Rough Country, and Rubicon Express. Always research reviews and compare specifications before making a purchase. Forums and off-road communities provide valuable insights.

What are the main differences between short arm and long arm kits?

Short arm kits use shorter control arms, offering less articulation and a harsher ride. Long arm kits, with their longer arms, provide superior articulation, improved ride quality, and reduce the chances of suspension binding, which can significantly improve performance.

Conclusion

Installing a Jeep XJ long arm kit is a significant upgrade that can dramatically improve your Jeep's off-road capabilities and ride comfort. By carefully considering your needs, choosing the right kit, and following proper installation and maintenance practices, you can transform your XJ into a more capable and enjoyable vehicle.
